in the text refer to the callouts in the figures and the parts drawing. NOTE: Always use Genuine Graco Parts and Acces- sories, available from your Graco distributor. Refer to the Product Data Sheet for the pump, Form No. 305–787. If you supply your own accessories, be sure they are adequately sized and pressure rated for your system. Fig. 2 is only a guide for selecting and installing sys- tem components and accessories. Contact your Graco distributor for assistance in designing a system to suit your particular needs. Prepare the Operator All persons who operate the equipment must be trained in the safe, efficient operation of all system components as well as the proper handling of all fluids. All operators must thoroughly read all instruction manuals, tags, and labels before operating the equip- ment. Prepare the Site The pump requires 150 scfm (4.2 m
/min) of com- pressed air while operating at 90 psi (6 bar, 0.6 MPa) air pressure and 60 cycles per minute. Ensure that you have an adequate compressed air supply. Refer to Fig. 2. Bring a compressed air supply line (A) from the air compressor to the pump location. Be sure all air hoses (A) are properly sized and pressure-rated for your system. Use only electrically conductive hoses. The air hose should have a 3/4 npsm(m) thread. Install a bleed-type shutoff valve (B) in the air line to isolate the air line components for servicing. Install an air line moisture trap and drain valve (C) to help re- move moisture from the compressed air supply. Keep the site clear of any obstacles or debris that could interfere with the operator’s movement. Have a grounded, metal pail available for use when flushing the system or draining the fluid filter. Grounding WARNING FIRE AND EXPLOSION HAZARD Before operating the pump, ground the system as explained below. Also read the section FIRE OR EXPLOSION HAZ- ARD on page 4. 1. Pump: use the ground wire and clamp (supplied). See Fig. 1. Loosen the grounding lug locknut (W) and washer (X). Insert one end of the ground wire (26) into the slot in lug (Z) and tighten the locknut securely. Connect the other end of the wire to a true earth ground. Fig. 1 W X 26 Z
 2. Air and fluid hoses: use only electrically conductive hoses. 3. Air compressor: follow manufacturer’s recommen- dations. 4. Spray gun: ground through connection to a prop- erly grounded fluid hose and pump. 5. Fluid supply container: follow your local code. 6. Object being sprayed: follow your local code. 7. Solvent pails used when flushing: follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continu- ity. 8. To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the gun.

WARNING A red-handled bleed-type master air valve (F) and a fluid drain valve (D) are supplied. These accesso- ries help reduce the risk of serious injury, including fluid injection and splashing of fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump. The bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump. The fluid drain valve assists in relieving fluid pres- sure in the displacement pump, hose, and gun. Triggering the gun to relieve pressure may not be sufficient.
The red-handled bleed-type master air valve (F) is required in your system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING above). Be sure the bleed valve is easily accessible from the pump, and is located downstream from the air filter/regulator (H).
The air filter/regulator (H) controls pump speed and outlet pressure by adjusting the air pressure to the pump. It also removes harmful dirt and moisture from the compressed air supply. Locate close to the pump, but upstream from the bleed-type master air valve (F).
The air manifold (J) provides ports for connecting lines to air-powered accessories.
The air relief valve (38) opens automatically to prevent overpressurization of the pump.
The fluid filter (4) or surge tank includes a 60 mesh (250 micron) stainless steel element to filter particles from the fluid as it leaves the pump. It includes the fluid drain valve (D), which is re- quired in your system to relieve fluid pressure in the hose and gun (see the WARNING at left).
The suction hose (8) and tube (7) allow the pump to draw fluid from a 5 gallon (19 liter) pail. Connect the Fluid Hoses and Gun NOTE: Models 237–296 and 238–906 include fluid hoses, a spray gun, and connecting parts (ref. nos. 102–106). If you supply your own fluid hoses and gun, be sure they are properly sized and pressure-rated for your system. Use only electrically conductive hoses. 1. Connect the main fluid hose (103) to the fluid filter (4) outlet. 2. Screw the coupling (105) onto the other end of the main fluid hose (103). 3. Screw the short whip hose (104) onto the coupling (105). 4. Screw the whip hose (104) onto the gun swivel (106). 5. Screw the gun swivel (106) onto the fluid inlet of the spray gun (102).

WARNING INJECTION HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray tips. 1. Lock the gun trigger safety. 2. Close the red-handled bleed-type master air valve (F, required in your system). 3. Unlock the gun trigger safety. 4. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure. 5. Lock the gun trigger safety. 6. Open the drain valve (D, required in your system), having a container ready to catch the drainage. 7. Leave the drain valve open until you are ready to spray again. If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip or hose. Packing Nut/Wet-Cup Before starting, fill the packing nut (K) 1/3 full with Graco Throat Seal Liquid (TSL) or compatible solvent. See Fig. 3. WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure at left. The packing nut is torqued at the factory and is ready for operation. If it becomes loose and there is leaking from the throat packings, relieve pressure, then torque the nut to 100–110 ft-lb (136–149 N.m) using the supplied wrench. Do this whenever necessary. Do not overtighten the packing nut. Flush the Pump Before First Use The pump is tested with lightweight oil, which is left in to protect the pump parts. If the fluid you are using may be contaminated by the oil, flush it out with a compatible solvent. See Flushing on page 10. Using the Airless Spray Gun Before operating the equipment, read the instruction manual supplied with the gun. Spray some test patterns before doing any finished work. Refer to the gun manual for detailed information on correct spraying technique.

surface. Failure to follow this caution could result in injury or equipment damage. Prime the Pump 1. See Fig. 3. Remove the tip guard and spray tip from the gun (102). See the gun instruction manu- al. 2. Close the air filter/regulator (H) and bleed-type air valves (B, F). 3. Close the fluid drain valve (D). 4. Connect the air line (A) to the air inlet swivel (G). 5. Check that all fittings throughout the system are tightened securely. 6. Place the suction tube (7) into the fluid supply container. 7. Open the bleed-type air valves (B, F). 8. Hold a metal part of the gun (102) firmly to the side of a grounded metal pail and hold the trigger open. 9. Slowly open the air filter/regulator (H) until the pump starts. 10. Cycle the pump slowly until all air is pushed out and the pump and hoses are fully primed. 11. Release the gun trigger and lock the trigger safety. The pump should stall against pressure. 12. If the pump fails to prime properly, open the drain valve (D). Use the drain valve as a priming valve until the fluid flows from the valve. Close the valve. NOTE: When changing fluid containers with the hose and gun already primed, open the drain valve (D) to help prime the pump and vent air before it enters the hose. Close the drain valve when all air is eliminated. Set the Air and Fluid Pressure WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. 1. Relieve the pressure. Install the tip guard and spray tip in the gun, as explained in the gun manu- al. 2. Open the air filter/regulator (H) slowly. Use the regulator to control pump speed and fluid pres- sure. Always use the lowest air pressure neces- sary to get the desired results. Higher pressures cause premature tip and pump wear. NOTE: To open the air filter/regulator, turn the T-handle in (clockwise). To close the regulator, turn the handle counterclockwise. To lock the regulator setting, tighten the jam nut. WARNING COMPONENT RUPTURE HAZARD To reduce the risk of overpressurizing your system, which could cause compo- nent rupture and serious injury, never exceed the specified Maximum Incoming Air Pres- sure to the pump (see the Technical Data, on page 18). 3. With the pump and lines primed, and with ade- quate air pressure and volume supplied, the pump will start and stop as you open and close the gun. CAUTION Do not allow the pump to run dry. It will quickly accelerate to a high speed, causing damage. If your pump is running too fast, stop it immediately and check the fluid supply. If the container is empty and air has been pumped into the lines, refill the con- tainer and prime the pump and the lines, or flush and leave it filled with a compatible solvent. Eliminate all air from the fluid system.

WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. For overnight shutdown, stop the pump at the bottom of its stroke to prevent fluid from drying on the ex- posed displacement rod and damaging the throat packings. Relieve the pressure. Always flush the pump before the fluid dries on the displacement rod. See Flushing below. Flushing WARNING FIRE AND EXPLOSION HAZARD Before flushing, read the section FIRE OR EXPLOSION HAZARD on page 4. Be sure the entire system and flushing pails are properly grounded. Refer to Grounding on page 5. Flush the pump:
Before the first use
When changing colors or fluids
Before fluid can dry or settle out in a dormant pump (check the pot life of catalyzed fluids)
Before storing the pump. Flush with a fluid that is compatible with the fluid you are pumping and with the wetted parts in your system. Check with your fluid manufacturer or supplier for recommended flushing fluids and flushing frequency. CAUTION Never leave water or water-base fluid in the pump overnight. If you are pumping water-base fluid, flush with water first, then with a rust inhibitor such as mineral spirits. Relieve the pressure, but leave the rust inhibitor in the pump to protect the parts from corrosion. WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8. 1. Relieve the pressure. 2. Remove the tip guard and spray tip from the gun. See the gun instruction manual. 3. Remove the filter element from the fluid filter (4) or surge tank. Reinstall the filter or surge tank bowl. 4. Place the suction tube (7) in a container of solvent. 5. Hold a metal part of the gun firmly to the side of a grounded metal pail. 6. Start the pump. Always use the lowest possible fluid pressure when flushing. 7. Trigger the gun. 8. Flush the system until clear solvent flows from the gun. 9. Relieve the pressure. 10. Clean the tip guard, spray tip, and fluid filter ele- ment separately, then reinstall them. 11. Clean the inside and outside of the suction tube (7).
