RESET THE BREAKER AND/OR REPLACE THE FUSE. LOOK FOR SHORT/OVERLOAD FAILURE AND REPAIR.
IS THE THERMAL O/L ON THE
BURNER MOTOR OR
BREAKER TRIPPED?
CHECK BELT TENSION (ADJUST IF NEEDED). ADJUST ENGINE RPM TO RUN WITH IN SPEC, VOLTAGE OUTPUT
CHANGES WITH GENERATOR SPEED. CHECK CAPACITOR FOR 16MFD (ARC TERMINALS WITH SCREW DRIVER
BEFORE TESTING. IF ALL THESE TEST GOOD, REPLACE GENERATOR.
UNPLUG THE FUEL SOLENOID AND CHECK THE TRANSFORMER FOR SPARK. !!CAUTION HIGH VOLTAGE!!
CHECK ELECTRODE ADJUSTMENT AND AIR BAND ADJUSTMENT (IMPORTANT!-SEE BURNER SPEC SHEET FOR
SETTING ELECTRODE GAP). CHECK ELECTRODES FOR CRACKS. REPLACE FUEL NOZZLE. REPLACE
INSULATION IF IT IS SATURATED WITH FUEL.
IS THERE FUEL VAPOR
COMING OUT OF THE
BURNER EXHAUST?
DO YOU HAVE 110-120 VAC
OUTPUT FROM THE
GENERATOR?
DOES THE LIGHT ON THE
BURNER SWITCH COME ON
WHEN THE TRIGGER IS
CHECK HEAT SWITCH/THERMOSTAT FOR CONTINUITY (THERMOSTAT MUST BE ADJUSTED TO HIGHEST
SETTING BEFORE TESTING-REPLACE IF NO CONTINUITY). CHECK PRESSURE SWITCH FOR CONTINUITY WHEN
MACHINE IS RUNNING AND WITH TRIGGER PULLED-REPLACE IN NO CONTINUITY.
IS THE SPRAY TIP INSTALLED?
IS THE TRIGGER BEING
PULLED AND PRESSURIZED
WATER SPRAYING?
REPLACE THE
PRESSURE OR
FLOW SWITCH
DOES THE LIGHT ON BURNER SWITCH
TURN OFF WHEN TRIGGER IS
RELEASED ON SPRAY GUN?
INSTALL SPRAY TIP, BURNER REQUIRES 1000 PSI TO
OPERATE, IF UNIT IS EQUIPPED W/DUAL LANCE WAND,
CLOSE VALVE TO INCREASE PRESSURE, VERIFY PROPER
NOZZLE SIZE.
TRIGGER MUST BE PULLED TO OPERATE PRESSURE/FLOW
SWITCH
IS THE SWITCH ENGAGED TO
"ON" POSITION?
!! CAUTION!! TURN UNIT OFF
IMMEDIATELY AND REPAIR
TROUBLESHOOTING ENDS: REPEAT PROCEDURE UNTIL TROUBLE FREE OPERATION IS OBTAINED
TURN THERMOSTAT UP TO A HIGHER TEMPERATURE
ADD FUEL. MINIMUM LEVEL MUST BE ABOVE PICK UP TUBE
IN TANK.
TURN BURNER SWITCH TO "ON" POSITION
IS THERE FUEL IN THE TANK?
THOROUGHLY CHECK OUT UNIT!
REPLACE ANY DAMAGED O-RINGS,
HOSES, TRIGGER GUN
ADJUST FUEL PRESSURE TO SPEC. CHECK / REPLACE FUEL FILTER & REPAIR ANY AIR LEAKS. IF PROPER
PRESSURE CANNOT BE OBTAINED, REPLACE FUEL PUMP.
IS THE FUEL PRESSURE 140
PSI (+ - 10 PSI)?
LOOSEN COPPER FUEL LINE.
PULL TRIGGER GUN. DOES
FUEL DISCHARGE FROM LINE?
PULL TRIGGER GUN. IF NO FUEL DISCHARGES FROM LINE CHECK ELECTRICAL CONNECTION. CHECK
VOLTAGE AT SOLENOID VALVE. IF VOLTAGE READING IS 115VAC OR HIGHER REPLACE SOLENOID VALVE. IF NO
VOLTAGE CHECK FLOW / PRESSURE SWITCH FOR CONTINUITY.
IS THE THERMOSTAT TURNED
UP?
