SERVICE AND ADJUSTMENTS
Carburetor
The carburetor of your high pressure washer is pre-sei
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.
^ 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.
^ WARNING: High engine speeds are dangerous and
increase the risk of personal injury or damage to
equipment.
_____________________
^ WARNING: Low engine speeds impose a heavy
load on the engine and when sufficient engine
power is not available could shorten engine life.

Preparing Pressure Washer for Storage
NOTE: if you do not plan to use your unit for 30 days or
more, unit should be prepared for storage.
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as the
carburetor, fuel filter hose or tank during storage. Also,
experience indicates that alcohoPbiended fuels (called
gasohol or using ethanol or methanol) can attract mois­
ture which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system
of an engine while in storage. To avoid engine problems,
the fuel system should be emptied before storage of 30
days or longer. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may
occur.
Engine Preparation
• First add a fuel stabilizer to the fuel tank.
• Run pressure washer for full 5 minutes to allow fuel
stabilizer to enter the fuel system.
NOTE: While doing this procedure make sure water
supply is turned on and flowing to the unit. NEVER run
unit without water supply running through pump.
• Next shut off engine and disconnect the water supply.
• Disconnect the spark plug wire and remove the spark
plug.
• Add one teaspoon of oi! through the spark plug hole.
Place rag over spark plug hole and pull the recoil a
few times to lubricate the combustion chamber.
Replace the spark plug, but do not connect the spark
plug wire.
Pump Preparation
This pressure washer should be stored in such a way to
protect it from freezing. Do not store this unit outdoors
or in an area where temperatures will fall below 32^^ F.
This can cause extensive damage to this unit.
If unit has to be stored under freezing conditions a non-
toxic R.V. anti-freeze can be used to protect from
freezing.
• Be sure engine switch is in “OFF" position and spark
plug wire has been removed from spark plug.
• Puli the trigger on the spay gun to release the
pressure in the high pressure hose. Detach high
pressure hose and garden hose from the unit.
• Pull the recoil on the engine 4 to 6 times to discharge
remaining water in pump.
• Tip the unit on the end with the water inlet fitting
pointing upward.
• Pour approximately 1/4 cup of non-toxic R.V. anti­
freeze down the fitting where the water hose attaches
to the pump,
• Set unit upright and pull starter handle on engine 4 to
6 times to circulate anti-freeze in pump until anti­
freeze is discharged from the pump.
