Clean Pre-Cleaner and Air Cleaner Cartridge
Your engine is equipped with an oval dual element air
cleaner: the two elements include a foam pre-cleaner
and an air cleaner cartridge.
• To remove the air cleaner element, loosen two cover
screws and lift cover. Carefully remove foam pre-
cleaner and air cleaner cartridge.
•
To clean pre-cleaner and air cleaner cartridge,
wash in liquid detergent and water. Allow to dry
thoroughly before using. Do not oil the precleaner
or cartridge. Replace if very dirty or damaged.
•
After cleaning the pre-cleaner and air cleaner
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.
Clean and Replace Spark Plug
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 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.

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.
NOTE: Do not use petroleum solvents, e.g., kerosene,
which will cause the cartridge to deteriorate. Do not
use pressurized air to clean cartridge. Pressurized air
can damage the cartridge.
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 ad-
justment.
High engine speeds are dangerous
and increase the risk of personal
injury or damage to equipment.
Low engine speeds impose a
heavy load on the engine and
could shorten engine life.
