WINTER STORAGE
NOTICE You must protect your unit from freezing
temperatures.
o Failure to do so will permanently damage your pump and
render your unit inoperable.
Freeze damage is not covered under warranty.
Draining Fuel Tank and Carburetor:
If fuel additive is not used, remove all fuel from tank
and carburetor.
• Place an approved fuel container below carburetor
and use a funnel to avoid spilling fuel.
• Remove carburetor drain bolt (A), then move fuel
valve lever to "On" position.
To protect the unit from freezing temperatures:
1. Follow steps 1-4 in the previous section After Each
Use.
.
.
Use pump saver, available at Sears, item 74403,
to treat pump. This minimizes freeze damage and
lubricates pistons and seals.
If pump saver is not available, connect a 3-foot
section of garden hose to water inlet adapter. Pour
RV-antifreeze (antifreeze without alcohol) into
hose. Pull recoil handle twice. Disconnect 3-foot
hose.
4. Store unit in a clean, dry area.
LONG TERM STORAGE
If you do not plan to use the pressure washer for more
than 30 days, you must prepare the engine and pump
for long term storage.
It is important to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, fuel
filter, fuel hose or tank during storage. Also, experience
indicates that alcohol-blended fuels (called gasohol,
ethanol or methanol) can attract moisture, which leads
to separation and formation of acids during storage.
Acidic gas can damage the fuel system of an engine
while in storage.
Protect Fuel System
Fuel Additive:
If adding a fuel additive, fill the fuel tank with fresh fuel.
If only partially filled, air in the tank will promote fuel
deterioration during storage.
• Add fuel additive following manufacturer's
instructions.
Make sure you have water supply to pump inlet
connected and turned ON.
Run the engine outdoors for several minutes to be
sure that treated fuel has replaced the untreated
fuel in the carburetor.
If fuel additive is not used, remove all fuel from tank
and run engine until it stops from lack of fuel.
After all fuel has drained into container, reinstall
drain bolt. Tighten both securely.
Change Engine Oil
While engine is still warm, drain oil from crankcase.
Refill with recommended grade. See Changing Engine
Oil.
Oil Cylinder Bore
• Remove spark plug. Squirt about a tablespoon of
clean engine oil into the cylinder. Cover spark plug
hole with rag. Pull recoil handle slowly to distribute
oil. Avoid spray from spark plug hole.
Install spark plug. DO NOT connect spark plug wire.
