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

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

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
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
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

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

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

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

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
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

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
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

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

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
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 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

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
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
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
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

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

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

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
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

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

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

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

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

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
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

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

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

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

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

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

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

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
