SERVICE AND ADJUSTMENTS

Carburetor

The carburetor of your high pressure washer is pre-set at the factory. The carburetor should not be tampered with. If your pressure washer is used at an altitude in excess of 5000 feet consult with your nearest Sears Service Center regarding high altitude set changes.

CAUTION: Engine speed was properly adjusted at the factory and should require no additional adjustment. Do not attempt to change engine speed. If you believe the engine is running too fast or too slow, take your pressure to a Sears Authorized Service Center for repair and adjustment.

WARNING: High engine speeds are dangerous and increase the risk of personal injury or damage to equipment.

CAUTION: Low engine speeds impose a heavy load on the engine and could shorten engine life.

Nozzle Cleaning

If the nozzle becomes clogged with foreign materials, such as dirt, excessive pressure may develop. If the nozzle becomes partially clogged or restricted, the pump pressure will pulsate. Clean the nozzle immedi- ately using the nozzle kit supplied and the following instructions.

•Shut off the pressure washer and turn off the water supply.

•Disconnect spark plug wire.

•Pull trigger on gun handle to relieve any water pressure.

•Disconnect the wand from the gun.
