STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

WATER PUMP

16

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

TO REMOVE BRASS COUPLINGS FROM OLD HOSE

1 Lock hose in vice and remove screw

2 Unscrew the brass coupling from hose turning counter-clockwise Use a bar or rod as needed

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

ENSURE A FLUSH SQUARE CUT TO HOSE A ROUGH CUT CAN RESULT IN SPRAY BACK OR EXPLOSION

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

Troubleshooting

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

SAFETY CHECKLIST (Before you drive away)

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

WATER PUMP

16

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

13

Unlock Abrasive LeverPress the Toggle

to Blast

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

SAFETY CHECKLIST (Before you drive away)

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

TO REMOVE BRASS COUPLINGS FROM OLD HOSE

1 Lock hose in vice and remove screw

2 Unscrew the brass coupling from hose turning counter-clockwise Use a bar or rod as needed

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

ENSURE A FLUSH SQUARE CUT TO HOSE A ROUGH CUT CAN RESULT IN SPRAY BACK OR EXPLOSION

18

CONSULT YOUR APPROPRAITE COMPRESSOR MANUAL FOR MAINTENANCE OPERATION AND SAFETY REQUIREMENTS

REPLACEMENT SCHEDULES ARE JUST A SUGGESTION BASED ON TYPICAL USE IN A CONTROLLED ENVIRONMENT AIR FILTER MAINTENANCE IS CRUCIAL FOR MACHINE PERFORMANCE REGULARLY CHECK YOUR SYSTEM AND REPLACE PARTS AS NEEDED

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

Troubleshooting

Please call the manufacturer directly with any additional maintenance questions1-800-727-5707 | supportdustlessblastingcom

YOUR SAFETY IS IMPORTANT TO US ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT BE AWARE OF YOUR SURROUNDINGS NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

WHEN STORING THE MACHINE REMOVE WATER AND MEDIA TO AVOID DANGEROUS CLOGGING AND DAMAGE DUE TO SOLIDIFICATION OR BUILDUP OF MEDIA

22

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

SAFETY CHECKLIST (Before you drive away)

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

WATER PUMP

16

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

WATER PUMP

16

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

13

Unlock Abrasive LeverPress the Toggle

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

SAFETY CHECKLIST (Before you drive away)

Trailer is evenly loaded

If carrying a pallet of media in the trailer the water tank should always be filled to evenly distribute weight

Toolboxes are latched and secured

Compressor canopy is lowered and secured

Loose objects are secured down with ratchet straps

Fill funnel and accessories are put away

Hoses are coiled and secured

TRAILER HOOKUP PROCEDURES

1 With the winding crank lower the trailer onto the 2 516rdquo ball hitch until the foot is just off the ground

2 Ensure the hitch is latched and safety pin behind the collar is installed

3 On the foot remove the pin raise the drop foot and pin it again at the highest setting

4 Retract foot the rest of the way with the winding crank

5 Hook up safety chains crossing them to make a cradle

6 Pull emergency brake clip out of its box

7 Loop the emergency brake clip through the safety chain receiver

8 Run this wire through the safety pin on the hitch to prevent slack from dragging on the ground

9 Plug the brake clip back into its box

10 Plug in lights and make sure they work

Towing Safety and Hookup Procedures

ALWAYS ENSURE TRAILER JACK IS IN THE PROPER POSITION

ALWAYS PARK IN A CONTROLLED SAFE ENVIRONMENT ON LEVEL GROUND BE AWARE OF YOUR SURROUNDINGS WHEN PARKING AND BLASTING

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

WATER PUMP

16

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

17

The pinch hose can be rotated and positioned in 4 ways1 Starting position 2 Rotate hose 180ordm (Figure A)3 Flip hose around (Figure B)4 Rotate hose 180ordm again

BLASTING WEAR PARTS

TO REMOVE BRASS COUPLINGS FROM OLD HOSE

1 Lock hose in vice and remove screw

2 Unscrew the brass coupling from hose turning counter-clockwise Use a bar or rod as needed

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

ENSURE A FLUSH SQUARE CUT TO HOSE A ROUGH CUT CAN RESULT IN SPRAY BACK OR EXPLOSION

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

If leaving unit for extended period of time you should blast the water and media out of machine OR

1 Fully depressurize machine 2 Remove 2 bolts from bottom flange of machine 3 Remove 2 lugs from bottom flange 4 Push casting and air hose out of the way 5 Remove air inlet jet and gasket 7 Flush out inside of equipment with water

Once media and water are out of machine reverse procedure

1 Put gasket on air inlet jet 2 Insert air inlet jet and gasket 3 Put casting up to bottom of machine 4 Use lugs and bolts to secure casting

Cold weather Considerations

Storing Machine

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

BEFORE BLASTING INSPECT MACHINE TO ENSURE COMPONENTS ARE APPROPRIATELY TIGHTENED

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

ENSURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

NEVER BLAST IN UNSAFE CONDITIONS AT 32degF RUBBING ALCOHOL CAN BE ADDED TO THE WATER TANK AT ROUGHLY A 1100 GALLON RATIO MORE ALCOHOL CAN BE ADDED IF NECESSARY UP TO 120 RATIO

IF STORING YOUR MACHINE IN FREEZING TEMPERATURES TAKE PRECAUTIONS TO PREVENT DAMAGE FROM FREEZING OPEN ALL OF THE BALL VALVES ON YOUR UNIT TO PREVENT MOISTURE FROM FREEZING AND EXPANDING IN THE VALVE

WHEN STORING THE MACHINE REMOVE WATER AND MEDIA TO AVOID DANGEROUS CLOGGING AND DAMAGE DUE TO SOLIDIFICATION OR BUILDUP OF MEDIA

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

13

Unlock Abrasive LeverPress the Toggle

to Blast

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

SAFETY CHECKLIST (Before you drive away)

If carrying a pallet of media in the trailer the water tank should always be filled to evenly distribute weight

Toolboxes are latched and secured

Compressor canopy is lowered and secured

Loose objects are secured down with ratchet straps

Fill funnel and accessories are put away

Hoses are coiled and secured

TRAILER HOOKUP PROCEDURES

1 With the winding crank lower the trailer onto the 2 516rdquo ball hitch until the foot is just off the ground

2 Ensure the hitch is latched and safety pin behind the collar is installed

3 On the foot remove the pin raise the drop foot and pin it again at the highest setting

4 Retract foot the rest of the way with the winding crank

5 Hook up safety chains crossing them to make a cradle

6 Pull emergency brake clip out of its box

7 Loop the emergency brake clip through the safety chain receiver

8 Run this wire through the safety pin on the hitch to prevent slack from dragging on the ground

9 Plug the brake clip back into its box

10 Plug in lights and make sure they work

15

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

WATER PUMP

16

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

2 Unscrew the brass coupling from hose turning counter-clockwise Use a bar or rod as needed

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

ENSURE A FLUSH SQUARE CUT TO HOSE A ROUGH CUT CAN RESULT IN SPRAY BACK OR EXPLOSION

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

Troubleshooting

Please call the manufacturer directly with any additional maintenance questions1-800-727-5707 | supportdustlessblastingcom

If leaving unit for extended period of time you should blast the water and media out of machine OR

1 Fully depressurize machine 2 Remove 2 bolts from bottom flange of machine 3 Remove 2 lugs from bottom flange 4 Push casting and air hose out of the way 5 Remove air inlet jet and gasket 7 Flush out inside of equipment with water

Once media and water are out of machine reverse procedure

1 Put gasket on air inlet jet 2 Insert air inlet jet and gasket 3 Put casting up to bottom of machine 4 Use lugs and bolts to secure casting

Cold weather Considerations

Storing Machine

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

BEFORE BLASTING INSPECT MACHINE TO ENSURE COMPONENTS ARE APPROPRIATELY TIGHTENED

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

ENSURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

NEVER BLAST IN UNSAFE CONDITIONS AT 32degF RUBBING ALCOHOL CAN BE ADDED TO THE WATER TANK AT ROUGHLY A 1100 GALLON RATIO MORE ALCOHOL CAN BE ADDED IF NECESSARY UP TO 120 RATIO

IF STORING YOUR MACHINE IN FREEZING TEMPERATURES TAKE PRECAUTIONS TO PREVENT DAMAGE FROM FREEZING OPEN ALL OF THE BALL VALVES ON YOUR UNIT TO PREVENT MOISTURE FROM FREEZING AND EXPANDING IN THE VALVE

WHEN STORING THE MACHINE REMOVE WATER AND MEDIA TO AVOID DANGEROUS CLOGGING AND DAMAGE DUE TO SOLIDIFICATION OR BUILDUP OF MEDIA

22

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

13

Unlock Abrasive LeverPress the Toggle

to Blast

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

SAFETY CHECKLIST (Before you drive away)

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

TO REMOVE BRASS COUPLINGS FROM OLD HOSE

1 Lock hose in vice and remove screw

2 Unscrew the brass coupling from hose turning counter-clockwise Use a bar or rod as needed

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

ENSURE A FLUSH SQUARE CUT TO HOSE A ROUGH CUT CAN RESULT IN SPRAY BACK OR EXPLOSION

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

Troubleshooting

22

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

13

Unlock Abrasive LeverPress the Toggle

to Blast

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

TO REMOVE BRASS COUPLINGS FROM OLD HOSE

1 Lock hose in vice and remove screw

2 Unscrew the brass coupling from hose turning counter-clockwise Use a bar or rod as needed

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

ENSURE A FLUSH SQUARE CUT TO HOSE A ROUGH CUT CAN RESULT IN SPRAY BACK OR EXPLOSION

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

Troubleshooting

Please call the manufacturer directly with any additional maintenance questions1-800-727-5707 | supportdustlessblastingcom

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

13

Unlock Abrasive LeverPress the Toggle

to Blast

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

SAFETY CHECKLIST (Before you drive away)

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

TO REMOVE BRASS COUPLINGS FROM OLD HOSE

1 Lock hose in vice and remove screw

2 Unscrew the brass coupling from hose turning counter-clockwise Use a bar or rod as needed

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

ENSURE A FLUSH SQUARE CUT TO HOSE A ROUGH CUT CAN RESULT IN SPRAY BACK OR EXPLOSION

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

Troubleshooting

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

13

Unlock Abrasive LeverPress the Toggle

to Blast

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

SAFETY CHECKLIST (Before you drive away)

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

TO REMOVE BRASS COUPLINGS FROM OLD HOSE

1 Lock hose in vice and remove screw

2 Unscrew the brass coupling from hose turning counter-clockwise Use a bar or rod as needed

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

ENSURE A FLUSH SQUARE CUT TO HOSE A ROUGH CUT CAN RESULT IN SPRAY BACK OR EXPLOSION

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

Troubleshooting

22

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

13

Unlock Abrasive LeverPress the Toggle

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

SLOWLY

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

SAFETY CHECKLIST (Before you drive away)

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

TO REMOVE BRASS COUPLINGS FROM OLD HOSE

1 Lock hose in vice and remove screw

2 Unscrew the brass coupling from hose turning counter-clockwise Use a bar or rod as needed

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

Open Blow Down ValveClose Air Inlet Valve

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

Close Blow Down ValveOpen Air Inlet Valve

STEP 5 Filling the blast pot with abrasive The DB500reg is designed to hold bull 20 gallons of clean water bull 200 lbs of abrasive (~4070 mesh size) bull 28 oz of Rust Inhibitor

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

ENSURE A FLUSH SQUARE CUT TO HOSE A ROUGH CUT CAN RESULT IN SPRAY BACK OR EXPLOSION

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

GETTING STARTEDSTART UP amp SHUT DOWN PROCEDURES

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

12

Connect Electric LineConnect Blast Hose

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

CAREFULLY READ ALL BLAST POT AND COMPRESSOR INSTRUCTIONS BEFORE BLASTING

WHEN FILLING THE WATER STORAGE TANK BEFORE TRAVELING ENSURE YOU IMPLEMENT A SAFE COUNTERWEIGHT TO EVENLY DISTRIBUTE THE WEIGHT BALANCE

STEP 8 Shutting DownWhile the compressor is running close the air inlet valve and open the blow down valve to release the pressure then close the compressor service valve Let the blast pot fully depressurize before turning off the compressor

STEP 7 Start Blastingbull Make any necessary adjustments to abrasive lever by

rotating the levers adjusting screw

bull Adjust the operating pressure with the valve behind the lower gauge

bull Adjust the vibrator petcock valve so that you feel maximum vibration at the head of the machine

bull To activate blast hose slowly start pressing the toggle switch of the red head controller

Note For best results try different blast patterns and angles to find the best work flow

Close Service Valve

Remove the fill cap by pulling the paddle up and turning the cap counter-clockwise Place the fill funnel in the opening and pour the proper amount of abrasive or rust inhibitor Once complete remove the funnel and replace the fill cap Everything will mix together during the blasting process

Remove Fill Cap

STEP 6 Pressurize the blast potBefore you start blasting you will need to pressurize the blast machine Make sure the abrasive lever is unlocked then close the blow down valve and open the air inlet valve When the machine pressurizes you will see the abrasive lever on the blast pot pop up

Note A valve is in the open position when it is aligned with the fixture that it controls

Note The air inlet valve and blow down valve will always be in opposite positions of each other

The DB800reg is designed to hold bull 30 gallons of clean water bull 300 lbs of abrasive (~4070 mesh size) bull 42 oz of Rust Inhibitor

ALWAYS USE THE PROVIDED MEDIA FILTER TO REDUCE THE LIKELIHOOD OF CLOGGING DEBRIS IN THE SYSTEM IS EXTREMELY DANGEROUS DO NOT OVERFILL

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT

YOUR MACHINE CAN USE A WIDE VARIETY OF NON-SOLUBLE ABRASIVE AND CLEANING MEDIUMS THAT SINK IN WATER PLEASE OBSERVE ALL RELEVANT SAFETY PRECAUTIONS FOR YOUR MEDIA OF CHOICE IMPROPER HANDLING OF MEDIA CAN BE DANGEROUS TO EQUIPMENT OPERATOR OR BYSTANDERS

IF YOU TURN THE COMPRESSOR OFF FIRST THE PRESSURE IN THE POT WILL BACKFLOW AIR WATER AND MEDIA INTO OTHER PARTS OF THE SYSTEM CAUSING THEM TO FAIL

OPEN AIR INLET VALVE SLOWLY TO AVOID SENDING LARGE AMOUNTS OF COMPRESSED AIR INTO THE MACHINE TOO QUICKLY THIS WILL CAUSE UNNECESSARY WEAR ON THE SYSTEM

14

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

WATER PUMP

16

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

YOUR SAFETY IS IMPORTANT TO US CAREFULLY READ ALL INSTRUCTIONS BEFORE BLASTING IMPROPER HANDLING CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

WATER PUMP

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE

TO REMOVE BRASS COUPLINGS FROM OLD HOSE

1 Lock hose in vice and remove screw

2 Unscrew the brass coupling from hose turning counter-clockwise Use a bar or rod as needed

TO ATTACH BRASS COUPLINGS TO NEW PINCH HOSE 1 Wrap the end of the hose in several layers of friction tape slightly beyond the point the brass will cover

2 Place coupling over friction tape and hose screwing clockwise until hose end pushes against inside brass ridge of coupling Use a bar or rod as needed to tighten

3 Wrap screws with Teflon tape and screw into designated holes Ensure components are secure

PINCH HOSE MAINTENANCE GUIDE

Rotate the pinch hose every 10-15 hours of blasting Regularly perform a visual and physical inspection to insure integri-

ty Look and feel for signs of wear softness or bulges Completely replace pinch hose before it fails or at least every 40

hours of use or 4 rotations

DO NOT SHAKE THE BLAST POT TO LOOSEN MEDIA

NOZZLE WEAR IS EXPECTED INSPECT YOUR NOZZLE FOR WEAR AND REPLACE AS NEEDED

NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT

REPLACEMENT IS TYPICALLY RECOMMENDED AT 400 HOURS OF DRY BLASTING AND 2000 HOURS OF WET BLASTING HOWEVER THE RATE OF WEAR DEPENDS ON ABRASIVE USED AND BLASTING METHOD REGULARLY INSPECT FOR DAMAGE OR WEAR AND REPLACE AS NEEDED

A B

FAILED PINCH HOSE CAN RESULT IN DAMAGE TO MACHINE SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS

ENSURE A FLUSH SQUARE CUT TO HOSE A ROUGH CUT CAN RESULT IN SPRAY BACK OR EXPLOSION

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

STEP 1 Connecting blast hose and electric line Connect the blast hose to the pinch hose at the top of the blast pot and insert the safety pins (there should be 2) Connect the electric line of your red head controller to the control box on the back of the blast pot

Getting Started

STEP 2 Open path from water tank to blast potThe water storage tank must be filled before you can start filling your blast pot Once the tank is filled open the water tank valve the water inlet valve and the overflow valve

You will need to turn on the compressor before you can activate the water pump to fill the blast pot

STEP 4 Filling the blast pot with waterOnce these valves are all opened and your compressor is turned on and warmed up you are ready to activate the water pump To do this turn on the cooler fan by flipping the toggle switch located on the back of the fan unit Next open the Air Pilot Valve on the MT1 (DB500) or MT2 (DB800) located near the pressure gauge

Fill the blast pot with clean water until the overflow valve starts to drain At this point close the air pilot valve to stop the flow of water Allow the overflow valve to finish draining then close it

Open Water Tank Valve

Open Water Inlet Valve Open Overflow Valve Open Air Pilot Valve

Open Service Valve

Allow the compressor to idle and warm up for about 15-30 seconds You will know the compressor is ready when you hear the engine sound change and see the pressure gauge climb Once fully warmed up go ahead and open the compressor service valve all the way

STEP 3 Starting the compressorBefore turning on your compressor make sure the service valves are in the closed position Start the compressor according to the manufacturers instructions

ALWAYS WEAR APPROPRIATE PROTECTIVE EQUIPMENT WHILE MAINTAINING OR OPERATING BLASTING EQUIPMENT NEVER ATTEMPT MAINTENANCE ON PRESSURIZED EQUIPMENT ALWAYS INSPECT MACHINE NOZZLES HOSES AND COUPLINGS PRIOR TO BLASTING

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

MEDIA BUILD UP INSIDE POT - ADJUSTING VIBRATOR VALVE

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

On the left side of your control box a small brass petcock valve controls the vibrator speed This vibrator valve must be open during blasting Adjust it so that you feel maximum vibration at the head of the machine This will insure that all of the media gets ldquoshakenrdquo to the bottom of the tank

Over time you could experience abrasive buildup inside the pot which actually changes the harmonics of the pot If the system is not feeding right adjust the valve allowing the pot to rattle more

ABRASIVE NOT FLOWING CORRECTLYbull Ensure proper Installation air pressure and abrasivebull Check media quality Your machine is made to run with clean high quality abrasive or media

NOTHING IS COMING OUT OF THE NOZZLE

The blast nozzle may become clogged with debris or blast media If this occurs shut down the machine then remove the nozzle and inspect for a rock or other foreign material

PINCH VALVE MALFUNCTIONING

1 Put the machine in the blowdown position2 Does the pressure gauge on the bottom left side of the control box read 903 Are all fittings tightly secured to the deadman and the back of the box4 Test the solenoid valve inside the control box

PROCEDURES FOR REMOVAL

You will want to unload the blast pot while it is empty of media or water Use caution when removing from the trailer as

the blast pot is very heavy Do not attempt in an unsafe environment or without adequate manpower

To remove blast pot from trailer

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Remove any remnant media or water from the blast pot

3 Disconnect the air hose electrical power line and water inlet hose from blast pot

4 Remove bolts and washers that connect the blast pot to the trailer The bolts have a thread-locker applied and

may require heating up before loosening Be sure to put these in a safe place so you can find them when it is time to

put the blast pot back on the trailer

5 Carefully and with team effort ndash remove the empty blast pot from the trailer

6 You will need to extend your current air hose and electrical power line with extensions as needed and reconnect

them to your blast pot

7 We recommend using a water hose to fill your blast pot instead of extending the water inlet hose

To load blast pot back onto trailer after work is complete

1 Make sure all water pressure and air pressure has been released from the blast pot

2 Completely empty out the blast pot of remnant water and media

3 Disconnect the air hose and electrical power line from blast pot

4 Carefully and with team effort ndash place the empty blast pot back onto the trailer This may be difficult as the blast

pot is very heavy

5 Once on the trailer and in the correct position Add a thread-locker to the mounting bolt threads and install the

mounting bolts and washers that connect the blast pot to the trailer Torque these mounting bolts to approximately

75 lb-ft

6 Reconnect the air hose electrical power line and water inlet hose to the blast pot

7 Any threaded fittings removed will require a thread sealing compound or tape upon re-installation

8 Remember to save and re-install any safety-clips that may have been removed during blast pot removal

Dustless Blastingreg Blast PotCONTROL BOX MAINTENANCEThe control box has its own pressure regulator This is already set properly from the factory and should not be tampered with under normal circumstances However if it gets changed accidentally make sure you readjust it to 90 PSI

CONTROL BOX VALVE (LOCATED IN CONTROL BOX) MAINTENANCEIt is time to service your control box valve when the shutoff time is longer than usual or the valve is not actuating properly

To service the control box valve (located in the control box) follow these steps or checkout our online academy

1 Depressurize the machine

2 Label each endcap left or right

3 Remove the 2 (two) screws and set endcaps aside

4 Remove piston

5 Lightly lubricate piston with supplied grease or install new piston

6 Install or replace any damaged gaskets or O-rings

7 Re-install both endcaps

PRESSURE REGULATOR

You rarely have to adjust the pressure because it is better to adjust with stand off distance Occasionally you should lubricate the threads on this knob with a lubricant such as lithium grease

REGULATOR

You will find the filter regulator on the left side of control box Like the moisture trap you should leave it cracked open so it can always drain to avoid water entering your control box valve

CONDENSING FAN

The condensing fan cools the hot air that comes out of the compressor You donrsquot really need the fan if yoursquore wet blasting but itrsquos very important if yoursquore dry blasting You should also turn it on when using a paint spray gun with your compressor

MOISTURE TRAP (MT1 or MT2)

The moisture trap collects water from the air running through the system Periodically drain it by opening the lever on the bottom Alternately open the lever on the bottom so it can constantly drain slowly

On the moisture trap you will find a regulator for the water pump We pre-set these regulators to about 80-90 PSI You may use the regulator for a painting setup but be sure to return it to 80-90 PSI when yoursquore done

WATER PUMP

16

Best Practices for Maintaining your MobileALWAYS DEPRESSURIZE THE MACHINE BEFORE PERFORMING ANY MAINTENANCE

MAKE SURE ALL GASKETS ARE PROPERLY REPLACED TO PREVENT LEAKS

TURN OFF CONDENSING FAN WHEN NOT IN USE TO AVOID BATTERY DRAIN

PERIODICALLY CHECK THE TORQUE SETTINGS ON THE VARIOUS WATER PUMP BOLTS THIS WILL ENSURE YOU DONrsquoT LOSE ANY AIR THROUGH THE WATER PUMP AND GET OPTIMAL PERFORMANCE
