WARNING INJECTION HAZARD Spray from the gun, 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 is a serious injury. The injury may look like just a cut, but it is a serious injury. Get immediate medical attention. Do not point the gun at anyone or at any part of the body.
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. 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. Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid being sprayed.

Setup 2. Fill packing nut (D). Fill packing nut full with Graco Throat Seal Liquid (TSL) (64) supplied. WARNING If you supply your own hoses and spray gun, be sure the hoses are electrically conductive, that the gun has a tip guard, and that each part is rated for at least 3000 psi (210 bar, 21 MPa) Working Pressure. This is to reduce the risk of serious injury caused by static sparking, fluid injection or over– pressurization and rupture of the hose or gun.
Setup Grounding How to use the pressure control WARNING Improper installation or alteration of the grounding plug will result in a risk of electric shock, fire or explosion that could cause serious injury or death. The pressure control controls the motor operation so the sprayer maintains constant fluid pressure at the pump outlet. Turn the pressure control knob fully counterclockwise to obtain the minimum setting. Turn the knob clockwise to increase pressure. See Fig. 6. 1.
Setup Pressure Relief Procedure 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.
Startup Use this procedure each time you start the sprayer to help ensure the sprayer is ready to operate and that you start it safely. 4. Turn pressure knob (E) to minimum setting. 5. Disengage gun safety latch. See Fig. 4. NOTE: If this is a first–time startup, flush the sprayer. See page 12. CAUTION 2. Don’t install spray tip until pump is primed! To reduce the risk of damage to the displacement pump packings, never run the pump without fluid in it for more than 30 seconds. 3.
Startup WARNING FIRE AND EXPLOSION HAZARD To reduce static sparking and splashing when priming, be sure the spray tip is not installed on the gun, and hold a metal part of the gun firmly to the side of a grounded metal pail. NOTE: Spray patterns will change as tips wear. Change spray tip if adjusting pressure will not improve spray pattern. 1 B 7. To prime hose, lower pressure to reduce splashing. Holding gun against pail, trigger gun and slowly increase pressure until pump starts.
Shutdown and Care WARNING INJECTION HAZARD To reduce the risk of serious injury, when instructed to relieve pressure, follow the Pressure Relief Procedure on page 8. 6. Flush sprayer at end of each work day and fill it with mineral spirits to help prevent pump corrosion and freezing. See page 12. 7. For very short shutoff periods, leave suction hose in paint, relieve pressure, and clean spray tip. WARNING 1. Relieve pressure.
Flushing When to flush Determine material to spray from column 1. Flush with material in column 2. Then follow recommendations in one of next three columns. CAUTION Do not leave water or water-based fluids in sprayer if it could freeze. Push water out with mineral spirits. Frozen fluid in sprayer prevents starting and may cause serious damage.
Flushing WARNING FIRE AND EXPLOSION HAZARD To reduce static sparking and splashing, always remove the spray tip from the gun, and hold a metal part of the gun firmly to the side of a grounded metal pail when flushing. 7. Lower pressure setting. Turn on sprayer. Maintaining metal-to-metal contact, trigger gun into flushing pail. Slowly increase sprayer pressure just until pump starts. Keep gun triggered until solvent flows freely from gun. Circulate solvent to thoroughly clean sprayer. Release gun trigger.
Troubleshooting WARNING INJECTION HAZARD To reduce the risk of serious injury, when instructed to relieve pressure, follow the Pressure Relief Procedure on page 8. CAUTION Thaw sprayer if water or water-based paint has frozen in it, due to exposure to low temperatures, by placing it in a warm area. Do not try to start sprayer until it has thawed completely or damage to motor and/or control board may occur. If paint hardened (dried) in sprayer, the pump packings and/or pressure transducer must be replaced.
Basic Problem Solving TYPE OF PROBLEM WHAT TO CHECK If check is OK, go to next check WHAT TO DO When check is not OK, refer to this column Electrical (continued) 4. Check motor brushes for the following: a. Loose terminal screws. b. Broken or misaligned brush springs. 4. Refer to page 21. a. Tighten. b. Replace broken spring and/or align spring with brush c. Clean brush holders. Remove carbon with small cleaning brush. Align brush leads with slot in brush holder to assure free vertical brush movement.
Intermediate Problem Solving TYPE OF PROBLEM WHAT TO CHECK If check is OK, go to next check WHAT TO DO When check is not OK refer to this column Low Output 1. Check for worn spray tip. 1. Follow Pressure Relief Procedure Warning on page 8, then replace tip. See your separate gun or tip manual. 2. Be sure pump does not continue to stroke when gun trigger is released. Plug in and turn on sprayer. Prime with paint. Trigger gun momentarily, then release and engage safety latch.
Intermediate Problem Solving TYPE OF PROBLEM WHAT TO CHECK If check is OK, go to next check WHAT TO DO When check is not OK, refer to this column Low Output 7. Check motor control board (22a) by substituting with a good board. 7. Replace board. See page 24. (continued) CAUTION: Do not perform this check until motor armature is determined to be good. A bad motor armature can burn out a good board. 8. Check motor armature for shorts by using an armature tester (growler) or perform motor test.
Intermediate Problem Solving TYPE OF PROBLEM WHAT TO CHECK If check is OK, go to next check Spray Pattern Variations (continued) 3. Check pressure adjustment potentiometer (77) by replacing it with a new one. Motor Is Hot and Runs Intermittently 1. Determine if sprayer was operated at high pressure 1. Decrease pressure setting or increase tip with small tips, which causes excessive heat build size. up. Building Circuit Breaker Opens As Soon As Sprayer Switch Is Turned On.
General Repair Information WARNING INJECTION HAZARD To reduce the risk of serious injury, when instructed to relieve pressure, follow the Pressure Relief Procedure on page 8. 3. Route wires carefully and avoid pinching any wires between covers. CAUTION Improper wire routing can result in poor sprayer performance or damage to the pressure transducer. Tool List These service tools are required.
Motor Test Armature Short Circuit Test WARNING 1. Remove fan cover (B). See Fig.12. INJECTION HAZARD To reduce the risk of serious injury, when instructed to relieve pressure, follow the Pressure Relief Procedure on page 8. For checking armature, motor winding and brush electrical continuity. 2. Spin motor fan by hand. If there are no shorts, the motor will coast two or three revolutions before coming to a complete stop.
Motor Brushes NOTE: Replace brushes when worn to about 12.5 mm (0.5 in.). Always check both brushes. Brush Repair Kit 236967 is available for motor brush repair. NOTE: Replacement brushes may last only half as long as the original ones. To maximize brush life, break in new brushes by operating the sprayer with no load as instructed in this procedure. NOTE: To minimize down time, and for best sprayer performance, check motor brushes and clean transducer (see page 28) whenever pump is repacked.
