General Repair Information Pressure Relief Procedure CAUTION To reduce risk of pressure control malfunction: WARNING INJECTION HAZARD System pressure must be manually relieved to prevent system from starting or spraying accidentally. Fluid under high pressure can be injected through skin and cause serious injury.
Troubleshooting Relieve pressure; page 5. Mechanical/Fluid Flow 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 or No Fluid/Pressure Output 1. Spray tip worn 1. Follow Pressure Relief Procedure Warning, then replace tip. See your separate gun or tip manual. 2. Spray tip clogged 2. Relieve pressure. Check and clean spray tip. 3. Paint supply 3. Refill and reprime pump 4. Intake strainer clogged 4.
Troubleshooting Electrical Symptom: Sprayer does not run or stops running D Relieve pressure; page 5. D Plug sprayer into correct voltage, grounded outlet D Set power switch OFF for 30 seconds and then ON again. This ensures sprayer is in normal run mode. D Turn pressure control knob clockwise 1/2 turn.
Troubleshooting Electrical DIGITAL DISPLAY Displays high pressure when prime valve is open and there is no pressure in sprayer. CONTROL BOARD STATUS LIGHT – Blinks 2 x repeatedly E=02 INDICATION Improper pressure signal to control Control board is receiving excessive pressure signal from transducer. Transducer may be damaged or fluid flow path may be clogged. WHAT TO DO Open prime valve. Connect a known good transducer in place of the sprayer transducer. Set sprayer ON.
Troubleshooting Electrical DIGITAL DISPLAY CONTROL BOARD STATUS LIGHT INDICATION WHAT TO DO E=05 Blinks 5 x repeatedly Possible locked pump or drive. May be motor connection or wiring error. 1. Check motor wiring connections 2. Check for locked or frozen pump or drive train 3. If all motor wiring connections are OK and pump/ drive train are not locked up, replace motor E=06 E=07 Blinks 6 x repeatedly Blinks 7 x repeatedly Motor is too hot or motor/thermal device connection may be bad.
