PROBLEMS

(SYMPTOMS)

The engine runs erratically or stops running.

POSSIBLE AREAS OF

MISADJUSTMENT(S)

OUTPUT PROBLEMS

1.Check that the fuel valve is fully open, and that there is sufficient, fresh gasoline in the tank.

2.The choke may be engaged. Be sure the choke handle is pushed in completely after the engine has begun to warm up.

3.Be certain that the battery is properly connected and adequately charged, even if using the recoil starter.

4.Check the engine oil level.

5.Check or replace the fuel filter.

6.Check or replace air filter.

7.Check spark plug; clean or replace if necessary.

8.Observe the oil level indicator light while cranking the engine. If the light is blinking while cranking the engine, the oil level may be low, or the oil level system may be faulty. Contact the engine manufacturer.

9.Perform any additional maintenance suggested in the engine operator’s manual.

RECOMMENDED

COURSE OF ACTION

1.Check the idle solenoid and engine carburetor linkage for damage, excessive dirt, or binding. If possible, perform the engine RPM adjustment procedure.

2.Place the engine switch in the “stop” position, unplug engine to welder harness connector (P4/J4) located inside the control box at the bottom left. CAUTION: Disconnecting this plug disables the normal engine shut down function of the engine switch. Reconnect P4/J4 to shut the engine down.

3.Attempt to start the engine using the recoil starter.

4.If the problem persists check for faulty insulation at the brown and brown/white wires connecting P4/J4 to the engine magneto. If the insulation is good, contact a qualified engine repair technician.

5.If the engine runs normally with P4/J4 disconnected, check for battery voltage between J3-10

(+) and J1-2 (-). If the voltage is low or erratic, check conductors and connections at GND-G, lead #211, lead 209A, and lead 230. Check the fuse, fuse holder, and the engine switch. Replace or repair any defective leads or components.

6.If the voltage between J3-10 (+) and J1-2 (-) is normal, check for defective insulation on lead 212. If insulation is good, replace PC board.
