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. Engine and fuel can
be stored up to 24 months with additive.
1. Add fuel additive following manufacturer's
instructions.
2. Connect water supply to pump inlet and turn it
ON.
3. Run engine outdoors for 10 minutes to be sure
treated fuel has replaced untreated fuel in
carburetor.
If fuel additive is not used, remove all fuel from tank
and run engine until it stops from lack of fuel.
Change Oil
While engine is still warm, drain oil from crankcase.
Refill with recommended grade. See "Changing Oil" on
page 14.
Oil Cylinder Bore
• Remove spark plug. Squirt about 1 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.
Protect Pump
To protect the pump from damage caused by mineral
deposits or freezing, use the PumpSaver (Sears item
number 7174403).
CAUTION!
Read and follow all cautions and
warnings on the PumpSaver can label. Always
wear eye protection when using PumpSaver.
To use PumpSaver, make sure the pressure washer is
turned off and disconnected from supply water. Read
and follow all instructions and warnings given on the
PumpSaver container.
NOTE: If PumpSaver is not available, draw RV
antifreeze (non-alcohol) into the pump by pouring the
solution into a 3-foot section of garden hose
connected to inlet adapter and pulling recoil handle
twice.
NOTE: PumpSaver will drip from pump after treatment
and will stain wood and concrete.
OTHER
• DO NOT store gasoline from one season to
another.
• If possible, store your unit indoors and cover it to
give protection from dust and dirt. BE SURE TO
EMPTY THE FUEL TANK.
IMPORTANT: NEVER cover your pressure washer
while engine and exhaust area are warm.
