OPERATING INSTRUCTIONS All operators must read this Owner’s Manual completely and thoroughly before operating the GPS-5K. They must be familiar with operating instructions and safety precautions. Unpacking the Sprayer In the shipping crate there should be one GPS-5K™ sprayer, one handgun in a box, and one handle. A box is attached to the hose reel with wire ties. The sprayer is fastened to the crate with 2 5/16”-18 threaded rods which run through the bottom of the sprayer frame. Unthread the top two nuts on each threaded rod with a ½” wrench. Remove the threaded rods from the sprayer frame. The sprayer is fastened to the crate with strapping material as well. Cut these remaining straps. The handgun box is fastened to the belt guard with 2 retaining straps; cut these straps. Carefully open the handgun box, remove the handgun, and unwrap the bubble wrap from the handgun. Check to make sure the serial number engraved on the handgun is the same as the number written on the outside of the box. If the numbers are different please contact the factory. Inside the box you should find the following: owner’s manual, handgun battery re-charger, and a handgun shoulder pad. Store the box and bubble wrap for future shipping. Place the handgun in the holster. A bag containing 1 extra flow disk, and 1 extra strainer is stapled to the cover of the manual; store it in a safe place for future use. These extra parts are in case of loss or damage to the original parts. See “The Air Filter” on p. 13 to replace the air filter. See “The Liquid Filter” on p. 14 to replace the flow disk and the strainer. A warranty registration card is also stapled to the front cover of the manual. After unpacking the sprayer, take time to fill this card out and send it in to ESS. This will insure your warranty protection in the event anything may happen to your sprayer or handgun.

Before Use The engine and the air compressor have been filled with the proper lubricant at the factory. However, their lubricant levels must be checked before the GPS-5K™ is operated. If they need to be replenished, use 30 weight compressor oil in the compressor and 10W-30 oil in the engine. Fill the gasoline engine tank with unleaded gasoline. About the Sprayer The GPS-5K™ is a self-contained unit. The engine provides power to the compressor to produce pressurized air. This air passes through the radiator, is cooled, and follows two different routes from a black iron tee. One route goes to the hose reel and in the red hose of the twin-line hose. The other route goes to the tank pressure regulator and then to the tank. When the engine is on and the tank pressure regulator is set between 12-15 psi, the tank is continuously pressurized and agitated to prevent separation and settling of the chemical. From the tank, the line goes to the hose reel and in the gray hose of the twin-line hose. The twin-line hose, which carries pressurized liquid and air lines, feeds into the handgun. The liquid combines with the pressurized air and atomizes into 40 micron VMD (volume mean diameter) drops. The droplets are electrostaticly charged and sprayed from the nozzle assembly. The droplets are attracted to all plant surfaces in the direction that the handgun points, including the back of leaves and foliage deep within the canopy, by means of an electrostatic charge.

REFERENCEThe Engine The GPS-5K™ uses a 5 horsepower gasoline engine (item 13) to power the air compressor. Before each spray operation, the gas and oil levels should be checked. Use lead-free gasoline and 10W-30 detergent oil. See “Regular Maintenance” on page 10 for periodic engine maintenance procedures.

To start engine: 1. Set the run/choke control to

choke (to the right). 2. Set the engine speed control to

fast (to the right). 3. Pull the starter cord. 4. After the engine engages,

move the run/choke control to run.

To stop engine: Move engine speed control to off (to the left). Note: Do not use choke to stop engine, as a backfire or engine damage may result.

To disconnect the quick connects: 1. Slide the sleeve on the quick

connect socket up. 2. While holding the sleeve up, pull the

socket off the quick connect plug. To connect the quick connects: 1. Slide the sleeve of the quick connect

socket up. 2. While holding the sleeve up, push

the socket onto the quick connect plug.

3. Release the sleeve. 4. Pull on the socket body to ensure

that it is properly seated and cannot be pulled off the plug when the sleeve is down.

The Compressor The compressor produces pressurized air which is used to atomize and propel the liquid. The oil level should be checked before each spray application. Only use 30-weight compressor oil in the compressor. See “Regular Maintenance” on page 10 for periodic compressor maintenance procedures. The Tongue Handle The tongue handle can be pulled by hand or attached to a small motorized vehicle for towing. In order to pull the sprayer, the vehicle must have a hole in the back end for a pin. Place a pin through the hole in the tongue handle and through the hole in the vehicle to pull the sprayer. ESS will not be held responsible for accidents which occur as a result of hazardous operations.

The Quick Connects There are four sets of quick connects (plug and socket) on the sprayer: tank inlet (items 57, 90), tank outlet (items 69, 77), handgun liquid inlet (items 76, 18-pg 21), and handgun air inlet (items 75, 20-pg 21).

The Hose Reel The hose reel contains the twinline hose running from the main unit to the handgun. Air (red hose) and liquid (gray hose) are plumbed into the hose reel from the compressor and liquid tank. There is a filter attached to the liquid inlet on the hose reel. The lifter consists of a strainer (item 93), o-ring (item 92(), and bowl. Periodically check and clean filter to clear any debris that may accumulate there. The Tank When the compressor is operating and the tank pressure gauge (item 49) is set between 12-15 psi, the liquid in the 5 gallon stainless steel tank (item 81) is continuously agitated. This helps prevent separation and settling of the chemical. There is a pressure valve lever on the tank lid which allows the operator to release pressure in the tank before opening. When the lever is

10

horizontal, the tank is pressurized; when the lever is vertical, the tank is not pressurized. You will hear a small amount of air escaping from the tank lid even when the lever is horizontal due to agitation. The tank should be thoroughly cleaned immediately after each use by triple-rinsing the tank; a commercially available tank cleaner may be used and is recommended when the XT™ is used to spray wettable powders on a regular basis.

To open the tank: 1. Push up the pressure valve lever on

the tank lid so it is vertical. This depressurizes the tank.

2. Pull the handle of the tank lid up. 3. Holding on to the handle, rotate the

tank lid 90° clockwise. 4. Pull out the tank lid. Notice the

direction of the tank lid in relationship to the tank opening.

To close the tank: 1. Slide the lid into the tank opening,

using the same direction as when it was removed.

2. Rotate the lid 90° counterclockwise. 3. While pulling the lid up to seal it

against the tank opening, push down on the lid handle until it is parallel with the tank lid.

4. Push the pressure valve lever down so it is horizontal.

To increase pressure: Turn the tee on the side of the regulator clockwise. To decrease pressure: Turn the tee on the side of the regulator counter-clockwise. Note: For best results, set the pressure from a lower pressure to a higher pressure. If the pressure is set too high, adjust the regulator below the desired pressure then adjust it up to the desired pressure.

Note: Do not operate the sprayer when the tank lid is not securely closed. Tank agitation is powerful and liquid may splash out if the lid is not closed.

The Tank Pressure Regulator The tank pressure regulator controls the amount of pressure in the tank pressure line. Optimum tank pressure is 15-15 psi.

The Pop-Off Valve The GPS-5K™ has a 100 psi spring-loaded pop-off valve which is connected to the tank pressure regulator. The valve relieves pressure greater than 100 psi to protect the sprayer from damage by extreme air pressure.

11

The Handgun The handgun is held by the operator during spraying. Activation of the trigger causes liquid to spray. The handgun has the following user-serviceable parts: the air filter, the liquid filter assembly, the nozzle assembly, and the batteries. Except for the batteries, which are accessed by removing the battery cover, nothing inside the handgun shell is user-serviceable. Do not open the handgun shell; doing so will void the warranty on the handgun.

To clean the air filter: 2. Unthread the casing from the cap

using a ¾” wrench on both parts. Be careful not to lose the spring or the air filter inside of the casing.

3. Check inside each part for debris. Clean any dirt out with compressed air or warm, soapy water.

4. Reassemble the air filter, making sure to put it together as in Diagram 2.

To engage/disengage the trigger: 1. Pull the trigger up towards the body

of the handgun to start spraying. 2. To keep spraying, either keep

holding the trigger or lock it in place by pulling up the lock and hooking the trigger.

3. To stop spraying when the trigger is not locked, let go of the trigger.

To clean the trigger: 1. Unthread the brass bolt on the top of

the handgun with a 5/8” socket wrench. Be careful not to lose the spring, plunger, copper washer, and small brass bushing inside the trigger. Note how they fit inside so they may be replaced properly.

2. Check inside the trigger for blockage. Clean out any debris with compressed air or warm, soapy water.

3. Replace the spring and plunger; rethread the brass bolt into the top of the handgun until tight.

The Air Filter The air filter is located outside the base of the handgun in the air hose. It filters dirt out of the air lines. There is an extra air filter in the bag which is stapled to this manual in case the original is lost or damaged.

Replacement parts for the air filter assembly are available as a kit. The kit includes a filter, and large and small o-rings. Order using ESS part number 231. The Trigger The trigger turns the spray on and off. It can be continuously held for operation or it can be locked in place. When it is on, the charging indicator on the top of the handgun shell glows red to indicate that the nozzles are charging.

Diagram 3. The Air Filter

Diagram 2. The Handgun

The Liquid Filter Assembly The liquid filter assemby is located outside the base of the handgun. It is composed of these parts: a 1/8” NPT body (item 10), a strainer (item 11), and a cap (item 12). The

strainer is the active filtering element in the volume of liquid that flows through the line. There is an extra flow disk and an extra striner in the bag which is stapled to this manual in case the originals are lost or damaged.

To disassemble, clean and reassemble the liquid filter assembly: 1. Using a 13/16” wrench on the cap and and 11/16” wrench on the 1/8” NPT body,

unthread them. Note: When you disassemble the liquid filter assembly, notice how the parts fit together in order to reassemble them properly. Be careful not to lose any parts, particularly the flow disk which is inside the cap. The sprayer will not function correctly without the flow disk.

2. Remove the strainer from the 1/8” NPT body. 3. If the 1/8” NPT body contains residue, clean it with compressed air or clean water. 4. Clean the strainer with compressed air or clean water. If residue still remains in the

50 mesh screen, disassemble the Strainer. Unscrew the top brass part from the bottom brass part. The 50 mesh screen slides off the brass body and can be cleaned with compressed air or clean water. If residue still remains, soak the 50 mesh strainer in water. If necessary, scrub it with a soft toothbrush to remove stubborn residue. Replace the 50 mesh screen and screw the top brass part back on the lower brass part.

5. If the flow disk is still in the cap, remove it. Check the aperture of the flow disk for blockage. If there is any, clean it with compressed air or clean water. Replace the flow disk so that the numbers on the disk face the strainer.

6. Replace the strainer in the 1/8” NPT body. 7. Rethread the 1/8” NPT body and the cap.

Diagram 4: The Liquid Filter Assembly

13

The Nozzle Assembly The nozzle assembly is located at the enc of the handgun wand. It is composed of a nozzle base, internal o-ring, Teflon ring, cover, external o-ring, and a hood (see Diagram 5). To access nozzle components, just unscrew the nozzle cover by hand. In order to optimize nozzle life and achieve maximum spray efficiency, the nozzle must be properly maintained. Always rinse the handgun out with clean soapy water after every spray, and establish maintenance intervals to disassemble and clean the nozzle. You may wish to purchase tank cleaner from ESS, p/# 1566, which cuts hard water scale and chemical deposits from the electrode and internal component of the gun. Your nozzle maintenance schedule will vary depending on the types of chemicals used and adherence to pre and post spray checks, In general it is sufficient to thoroughly clean nozzles every 50 hours. If heavy loads of wettable powers are used, the cleaning schedule should be sooner. Pre-Spray Check I. Inspect Nozzles Check nozzle cover to make sure it is on hand tight (do not over tighten or use a wrench). Make sure the hood is seated firmly to the nozzle base and against the external o-ring. II. Preparing the Tank Mix If you will be spraying wettable powders it is a good idea to use a compatibility agent with the water and tank mix. Compatibility agents are chemicals mixed with the water that make mixing easier and keep heavy concentrations uniformly in suspension. Some brand name additives are COMPLIMENT™, UNITE®, and BALANCE™. Check with your local chemical supplier for others that are available.

Post-Spray Check After each spray it is essential that hoses and handgun be flushed with clean soapy water. This will help prevent chemical build-up that can clog lines and nozzles. Also, it is recommended that the nozzle exterior (black portion of nozzle) and nozzle hoods be cleaned with soapy water at this time. To clean the nozzle assembly: 1. Slide the hood over the nozzle cover. 2. Unscrew the cover from the nozzle base

and remove the Teflon ring. Note: There is a small o-ring in the nozzle around the base of the tip, take care that it doesn’t fall off. If it does, clean it and press back into place. Also, take care not to damage the nozzle tip when the cover is removed.

3. Soak the ring, cover, and hood in a mild detergent solution. Use a small brush (soft or mild bristle) to clean the inside of the cover and the hole through it. Also, be sure to clean the hood. Rinse.

4. Scrub the nozzle base with the detergent solution using a soft bristle brush. Be sure to thoroughly clean the base cavity and take care not to damage the nozzle tip. Rinse and make sure the small o-ring is in place.

5. Reassemble nozzle by placing the Teflon ring on the base and screwing the cover on hand tight. Next, slide the hood over the nozzle and seat it securely against the external o-ring.

Diagram 5: The Nozzle Assembly 14

The Batteries The nozzle charging operates on two 9 volt rechargeable batteries which are located in the base of the handgun. In average conditions, the batteries will last 5-10 hours of operation on a charge. They should be recharged when the charging indicator on top of the handgun shell doesn’t glow when the trigger is engaged during operation. After a while the batteries will wear out and need to be change. Replace with Nickel-Hydride rechargeable batteries.

To change the batteries: 1. Unscrew the 2 6-32 x ½” phillips

head machine screws which hold the battery cover in place.

2. While holding the leads in one hand, gently disconnect the batteries from the leads. Be careful not to tear the leads off the wires or the tear the lead wires out of the power supply.

3. Connect 2 fresh 9 volt batteries to the leads.

4. Replace the battery cover. Screw the 2 6-32 x ½” Phillips head machine screws back in to secure the battery cover.

Spraying with Your ESS Sprayer Unlike conventional sprayers, your ESS sprayer uses a different method for chemical application. Therefore, new techniques must be used to spray and new formulas developed to properly prepare tank mix. This section will discuss proper spray techniques and how to prepare a tank mix. Note: When using unfamiliar equipment or chemicals, always test on a small area before treating the entire crop. Do not use a chemical with the ESS sprayer if the label prohibits use in low-volume sprayers. Spray Technique The technique by which crops are sprayed is very important. The ESS jhandgun is designed to propel the spray into the foliage by air-assistance. The spray is then attracted to all plant surfaces, including leaf undersides, and coats them evenly by and electrostatic charge. Because of this penetration, it is unnecessary for the spray want to be inserted into the canopy of each plant and turned over, as is done with hydraulic sprayers. Instead, the ESS handgun should be used much like a spray painter. Point the gun down slightly to cause the spray to flow into the plants. The leaves should rustle as the spray hits them. Sweep the handgun over the foliage at an even pace—approximately twice as fast as with a hydraulic sprayer. Do not spray to wet; the leaves should barely glisten. A slower spray speed can be compensated for by using a larger amount of water in the tank mix in order to spray the right amount of chemical (see Preparing a Tank Mix for more detail).

Note: Water temperature must be at least 50°F (10°C). When the liquid and air meet in the nozzle, the temperature of the liquid deceases. As a result, water at temperatures below 50 may freeze and clog the nozzle. Note: ESS recommends that the tank not be filled over the 4 gallon mark, since the force of agitation may cause liquid to escape through the air bleed hoe in the tank lid.

Preparing a Tank Mix The tank mix depends on two factors: water requirement and dosage. Water requirements is the amount of water needed to cover the given treatment area. Dosage is the amount of chemical which should be applied in a given treatment area.

First determine the water requirement for your sprayer over a known area. An easy way to determine water requirement is to spray a trial application with water. Put 2 gallons of clean water in the ESS tank and thoroughly spray a known area either inside a greenhouse or outside crops. One gallon should take about 15 minutes to spray and cover between ¼ to ½ of an acre. After spraying the known area, determine how much water was used from the amount left in the tank. This is the water requirement for the given area. Next measure the known area to determine how many square feet were sprayed. Write down both values for future reference. ___________ (gallons) Water Requirement for __________________ (size of known area in ft2) Example: 1 gallon of water for 5,000 ft2

Next determine the dosage. This is the amount of chemical you wish to dispense in a given area. Appropriate dosage depends upon chemical label recommendations, level of pest or disease infestation, crop type, crop maturity, crop density, past experience with particular chemicals, and other variables. ESS recommends that you start spraying using the same chemical rate used in the past in either hydraulic or air assisted sprayers. For example, if in the past you have used 2 ounces of chemical in a hydraulic sprayer to spray a known area; then mix 2 ounces of chemical to the water required by the GPS-5K™ to spray the same

16

known area. In other words, the same amount of chemical is sprayed out in the area but with much less water (see diagram). After becoming familiar with the sprayer spraying at full rate, you can start reducing the amount of chemical used for each

spray. Keeping the amount of water in the tank constant, cut the amount of chemical mixed in by 15-25% for each spray until a desirable kill is no longer achieved. If you are planning to cut rates then it is very important to scout your crop to determine spray efficiency.

17
