the factory. The carburetor should not be tampered with. If

 

 

your pressure washer is used at an altititude in excess of

 

 

5000 feet consult with your nearest Sears Service Center

 

 

regarding high altitude set changes.

 

 

ENGINE SPEED

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 washer to a Sears Authorized Service Center for repair and adjustment,

Use the wire included in the kit or small paper clip to free foreign materials clogging or restricting the nozzle. Move the wire back and forth to clear obstruction.

Changing engine governed speed will void engine warranty.

Your pressure washer runs at a constant speed. This con- stant operating speed is maintained by a mechanical, fly-

weight type, fixed speed governor. DO NOT tryto adjust the governed speed setting for the following reasons:

High engine speeds are dangerous and increase the risk of persona! injury or damage to equipment.

°Low engine speeds impose a heavy toad on the engine when sufficient.engine power is not available and may shorten engine life.

Remove additional debris by back flushing Water sup- ply through wand. Back flush between 30 to 60 sec- onds. Turn wand to stream spray and move nozzle from tow to high pressure while flushing.

NOZZLE MAINTENANCE

If the nozzle becomes restricted or clogged with foreign materials, such as dirt, excessive pump pressure may develop. A partially clogged nozzle can cause a pulsing sensation during use. This generally is not a pump related problem, but rather a clogged or partially restricted nozzle.

If the nozzle becomes clogged or partially restricted, immediately clean the nozzle with the kit included with your pressure'washer by following these instructions:

°Shut off the engine and turn off the water supply.

*Separate the wand from the gun.

• Open to stream spray.

Reinstall nozzle into wand. DO NOT overtighten. ° Reconnect wand extension to spray gun.

°Reconnect the water supply, turn ONthe water, and start the engine.

Test the pressure washer by operating with nozzle in the high and the tow pressure positions.
