Motor or control is damaged. Return sprayer to Graco authorized service center. Paint is frozen or hardened in pump. Unplug sprayer from electrical outlet. NOTE: If frozen, do not try to start sprayer until completely thawed, or damage to motor, control board, and/or drivetrain may occur. Make sure power switch is OFF. Place sprayer in warm area for several hours, then plug in and turn on. Slowly increase pressure setting to see if motor starts. If paint hardened in sprayer, pump packings, valves, drivetrain, or pressure switch may need to be replaced. Cannot pull In–line Valve trigger. Trigger safety is in SAFETY ON position. Put trigger safety in SAFETY OFF position. In–line Valve stops spraying. Tip is clogged. Aim In–line Valve into waste pail. Squeeze trigger. Pump cycles but does not build up pressure. (i.e., will not stop cycling even thoughnot stop cycling even though gun trigger is released) Pump check valves are dirty or damaged. Clean or replace check valves. Spray/Prime valve is worn or obstructed with debris. Return sprayer to Graco authorized service center. Pump is not primed. See Priming on page 9. Inlet screen is clogged or suction tube is not immersed. Clean debris off inlet screen. Make sure suction tube is at bottom of pail. Reprime sprayer. Paint pail is empty. Refill paint pail and reprime sprayer. Suction tube has vacuum air leak. Tighten suction tube connection. Inspect for cracks or vacuum leaks. If cracked or damaged, replace suction tube. Pump check ball is stuck. See “Pump will not prime” section of Trouble Shooting instructions. 28 309388 Troubleshooting PROBLEM CAUSE SOLUTION Pump cycles but paint only dribbles or spurts when trigger is pulledtrigger is pulled. Pressure is set too low. Turn Pressure Control Knob to the right (clockwise) to increase pressure. Tip is clogged. Clear tip. See your gun manual. Spray tip is too large or worn. Replace tip. Gun filter is clogged. Clean or replace In–line Valve fluid filter. Page 25. Pressure is set at maximum, but cannot achieve a good ttspray pattern. Extension cord is too long or not a heavy enough gauge. Replace extension cord. Tip is too large for sprayer. Select a smaller tip. Tip is worn beyond capability of sprayer. Replace tip. Gun filter is clogged. Clean or replace In–line Valve fluid filter. Page 25. Inlet screen is clogged. Clean debris off inlet screen. Pump valves are worn. Check for worn pump valves as follows: Prime sprayer with paint. See Priming on page 9. Trigger In–line Valve momentarily. When trigger is released, pump should cycle momentarily and stop. If pump continues to cycle, pump valves may be worn. Replace check valves. When paint is sprayed, it runs down the wall or sagsdown the wall or sags. Coat is going on too thick. Move gun faster. Choose tip with smaller hole size. Choose tip with wider fan. Make sure gun is far enough from surface. When paint is sprayed, coat is not coveringnot covering. Coat 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. Motor is hot and runs intermittentlyintermittently. NOTE: This is a thermalNOTE: This is a thermal overload condition. Motor will automatically shut off due to heat.excessive excessiveexcessive heat. See Startup Hazard After Thermal Overload on page 2. Damage can occur if2. Damage can occur if cause is not corrected. Vent holes in shroud are plugged or sprayer isplugged, or sprayer is covered. Keep vent holes in shroud clear of obstructions and overspray, and keep sprayer open to airand keep sprayer open to air. Extension cord is too long or not a heavy enough gauge. Replace extension cord. Unregulated electrical generator being used has excessive voltage. Use electrical generator with a proper voltage regulator. Sprayer requires a 120V AC, 60 Hz, 1500-Watt generator. Sprayer was operated at high pressure with small tip, which caused frequent motor starts and excessive heat build up. Decrease pressure setting, or increase tip size. Building circuit breaker opens after sprayer operates for 5 to 10 minutes10 minutes. OR Building circuit breaker opens as asas soon soonsoon as asas sprayer sprayersprayer is isis plugged pluggedplugged Too many appliances are plugged in on same circuit. Free up circuit (unplug things), or use a less busy circuit. Extension cord is damaged or too long or not a heavy enough gauge. . Plug in something that you know is working to test extension cord. . Replace extension cord. into outlet, and sprayer is turned on. Sprayer power cord is damaged. Check for broken insulation or wires. Replace power cord if damaged. 309388 29 Fan pattern varies dramatically while spraying or sprayer does not turn on promptly when resuming spraying. Pressure control switch is worn and causing excessive pressure variation. Return sprayer to Graco authorized service center. Spray comes out of gun in two thick streams. Reversible tip is in UNCLOG position. Rotate arrow–s...
