WARNING SKIN INJECTION HAZARD Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury. Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgical treatment. Do not point the gun at anyone or at any part of the body. Do not put your hand or fingers over the spray tip.
WARNING FIRE AND EXPLOSION HAZARD Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury. Ground the equipment and the object being sprayed. Refer to Grounding on page 5. If there is any static sparking or you feel an electric shock while using this equipment, stop spraying immediately. Do not use the equipment until you identify and correct the problem.
Installation Z General Information Y NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawing. NOTE: Always use Genuine Graco Parts and Accessories, available from your Graco distributor. 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 system components and accessories.
Installation Refer to the Typical Installation drawing (Fig. 2). WARNING A bleed-type master air valve (D) and a fluid drain valve (J) are required in your system. These accessories help reduce the risk of serious injury, including skin 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.

Operation Pressure Relief Procedure WARNING SKIN 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.
Operation Starting and Adjusting the Pump See Fig. 2 on page 7. Be sure the air regulator (E) and bleed-type master air valve (D) are closed. Do not install the spray tip yet! Connect a suction hose (N) to the pump’s fluid inlet. Hold a metal part of the spray gun (M) firmly to the side of a grounded metal pail and hold the trigger open. Then open the pump’s bleed-type master air valve (D). Now slowly open the air regulator until the pump starts, about 40 psi (0.3 MPa, 3 bar).
Operation Shutdown and Care of the Pump WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 9. For overnight shutdown, relieve the pressure. Always stop the pump at the bottom of the stroke to prevent the fluid from drying on the exposed displacement rod and damaging the throat packings. CAUTION Never leave water or water-base fluid in the pump overnight.
Troubleshooting NOTE: Check all possible problems and solutions before disassembling the pump. PROBLEM CAUSE SOLUTION Pump fails to operate. Restricted line or inadequate air supply. Clear line; increase air supply. Insufficient air pressure; closed or clogged air valves, etc. Open, clean. Exhausted fluid supply. Refill; purge all air from pump and fluid lines. Damaged air valving mechanism; stalling. Service air motor (see manual, supplied). Dried fluid seizure of displacement rod (26).
Service Disconnecting the Displacement Pump Model 223586 Shown WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 9. 1. Flush the pump if possible. Stop the pump at the bottom of its stroke. Relieve the pressure. 2. Disconnect the air and fluid hoses. Remove the pump from its mounting. Note the relative position of the pump’s fluid outlet to the air motor’s air inlet. 3. See Fig. 4.
Service Displacement Pump Service Disassembly When disassembling the pump, lay out all removed parts in sequence, to ease reassembly. Refer to Fig. 5. NOTE: Repair Kit 235635 is available. For the best results, use all the new parts in the kit. Parts included in the kit are denoted with an asterisk, for example (17*). Reassembly 1.
Service 26 1 1 Torque to 18–20 ft–lb (24–27 N.m) 2 Torque to 55–65 ft–lb (74–88 N.m) 3 Lips of v-packings must face down. 4 Lips of v-packings must face up. 5 Tapered end must face down, toward pump intake (33). 6 Apply thread lubricant. 7 Lubricate.
