and an air cleaner cartridge.

in liquid detergent and water. Allow to dry thoroughly
before using. Do not oil the precleaner or cartridge.

cartridge, replace pre-cleaner on air cleaner car
tridge.
• Install air cleaner assembly (pre-cleaner and
cartridge) in base. Then install cover on air cleaner
and tighten screws securely to base.

which will cause the cartridge to deteriorate. Do not use
pressurized air to clean cartridge. Pressurized air can
damage the cartridge.

Change the spark plug every 100 hours of operation or
once each year, whichever comes first. This will help
your engine to start easier and run better.
SERVICE AND A
djustments
Carburetor
The carburetor of your high pressure washer is pre-set
at the factory. The carburetor should not be tampered
with. If you pressure washer is used at an altitude in
excess of 5000 feet consult with your nearest Sears
Service Center regarding high altitude set changes.
A 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.
A WARNING:High engine speeds are dangerous and
increase the risk of personal injury or damage to
equipment.
A 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.
1. Shut off the pressure washer and turn off the water
supply.
2. Disconnect spark plug wire.
