Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. Refer back to these warnings. Additional, product specific warnings may be found throughout the body of this manual where applicable. WARNING FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode.
Warnings WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. Read Technical Data in all equipment manuals. • Use fluids and solvents that are compatible with equipment wetted parts. Read Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about your material, request MSDS from distributor or retailer.
Installation Installation Grounding and Electric Requirements Fluid supply container: follow local code. Sprayer must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for electrical current due to static build up or in the event of a short circuit. Grounding the metal pail: connect a ground wire to the pail by clamping one end to pail and other end to ground such as a water pipe.

General Repair Information To reduce risk of serious injury, including electric shock: Flammable materials spilled on hot, bare, motor could cause fire or explosion. To reduce risk of burns, fire or explosion, do not operate sprayer with cover removed. • Keep all screws, nuts, washers, gaskets, and electrical fittings removed during repair procedures. These parts usually are not provided with replacement kits. • Test repairs after problems are corrected.
Basic Troubleshooting Basic Troubleshooting Check everything in this Basic Troubleshooting Table before you bring the sprayer to a Graco/MAGNUM authorized service center. Problem Project Painter 5 and Project Painter 7 AllControl is on and sprayer is plugged in, but motor does not run, and pump does not cycle, or motor continues to run in OFF position. Cause Solution Project Painter 5 and Project Painter 7 AllControl is set at zero pressure. Turn AllControl clockwise to increase pressure setting.
Basic Troubleshooting Problem Pump does not prime. Cause Inlet valve check ball is stuck. Solution Remove suction tube and place a pencil into the inlet section to dislodge the ball, allowing pump to prime properly. OR Power Flush sprayer (see Operation manual). AutoPrime may need replacement. For Project Painter 7: plug in unit and listen for “tap” in pump. SR7 and ProX7 and 9: turn power switch ON and listen for “tap” in pump. If you do not hear “tap”, AutoPrime is damaged.
Basic Troubleshooting Problem Pump cycles, but paint only dribbles or spurts when spray gun is triggered. Cause Pressure is set too low. Solution Project Painter 5 and Project Painter 7 Sprayers -Slowly turn AllControl to HI SPRAY to increase pressure setting or SR7, ProX 7 and ProX9 - Turn Pressure Control Knob clockwise to increase pressure setting which will turn on motor to build pressure. Spray tip is clogged. Unclog spray tip (see Operation manual).
Basic Troubleshooting Problem When paint is sprayed, it runs down the wall or sags. Cause Coat is going on too thick. Solution Move gun faster. Choose a tip with smaller hole size. Choose tip with wider fan. Make sure gun is far enough from surface. When paint is sprayed, coverage is inadequate. Paint coating is going on too thin. Move gun slower. Choose tip with larger hole size. Choose tip with narrower fan. Make sure gun is close enough to surface. Fan pattern varies dramatically while spraying.
Advanced Troubleshooting Advanced Troubleshooting See Basic Troubleshooting first, page 17 for problems that are more easily remedied. General Problem: Motor Does Not Operate Specific Problem Cause Power switch is on and sprayer is plugged in; pump does not cycle. See Basic Troubleshooting, page 17. Basic mechanical problems. Paint is frozen or hardened in pump. Solution Unplug sprayer from electrical outlet.
Advanced Troubleshooting Specific Problem Basic electrical problems. Cause Solution Motor overheated. Allow motor to cool for 45 minutes. Retry. Electrical outlet is damaged. Reset building circuit breaker or replace fuse. Try another outlet. Check electric supply with volt meter. Meter must read 85 to 130V AC. If voltage is too high, do not plug sprayer in until outlet is corrected. Control board leads are improperly Replace any loose terminals. Make sure all leads and fastened or improperly mated.
Advanced Troubleshooting Specific Problem Sprayer Wiring Problems Cause Sprayer electrical cord damaged. NOTE: Remove enclosure mounting screws and pull enclosure away from drive housing. Take care not to pull on leads from electrical cord and power switch. Solution Unplug sprayer electrical cord. Disconnect black electrical cord wire at power switch. Unplug in-line connection white cord wire. Plug in electrical cord. Test voltage between black and white wires. Meter must read 85 to 130V AC.
Advanced Troubleshooting General Problem: Circuit Breaker is Tripping Specific Problem Cause Building circuit breaker opens as soon as sprayer is turned on. Solution Sprayer electrical wiring is pinched Repair or replace any damaged wiring or terminals. or insulation is damaged. Securely reconnect wires. Wires between pressure control switch and control board are pinched. Motor armature is shorting. Check for shorts using armature tester (growler) or perform spin test, Motor Diagnostics, page 30.
Advanced Troubleshooting General Problem: Low or Fluctuating Output Specific Problem Pump cycles, but output is low or surging. Cause Solution See Basic Troubleshooting, page 17. Worn or obstructed pump valves. Check for worn pump valves as follows: Prime sprayer with paint. Trigger spray gun momentarily. When spray gun trigger is released pump should cycle momentarily and stop. If pump continues to cycle, pump valves may be worn or obstructed. Pump Service, page 31.
Advanced Troubleshooting Specific Problem Cause Solution Control board is damaged. See Control Board Diagnostics, page 31. If damaged replace control board using Control Board Kit, page CAUTION: Do not perform control 28. board diagnostics until you have determined the armature is good. A damaged armature can burn out a good control board. Motor runs and pump cycles, but pressure does not build up.
Advanced Troubleshooting General Problem: No Output Specific Problem Project Painter 5 and Project Painter 7 - AllControl is ON Cause Solution See Basic Troubleshooting, page 17. or SR7, ProX7 and ProX9 - Power switch is on and sprayer is plugged in but pump does not cycle Motor runs but pump does not cycle. Gear and/or yoke are damaged Replace gear and yoke using Gear/Yoke Repair Kit, page 28. Motor does not run. Water or paint entered pressure control switch or shorted control board.

Motor Diagnostics Motor Diagnostics Check for electrical continuity in motor armature, windings and brush as follows: If Motor Diagnostics reveal a damaged motor or if motor brushes are shorter than 1/4 in. (6.4 mm) or if the motor shaft cannot turn, replace the motor using Motor Kit, page 28. Armature Short Circuit Spin Test Setup 1. Relieve pressure, page 14. 2. Unplug electric cord. 3. Remove enclosure and disconnect motor leads from control card. 4. Remove fan brace (if equipped). 5.
Control Board Diagnostics Control Board Diagnostics Check for motor problems before replacing control board. A damaged motor may burn out a good control card. Check for a damaged control board or pressure control switch as follows: 7. Attach harness from a pressure control switch you know is functioning correctly to control board. Pressure control switch does not have to be installed in pump. 1. Relieve pressure, page 14. 2. Unplug electrical cord. 8.
