Prepare Engine for Long Term Storage
First prepare the engine for long term storage if you
will not be using the pressure washer for more than
30 days.
Fuel can become stale when stored over 30 days. Stale
fuel causes acid and gum deposits to form in the fuel
system which can cause malfunction of the engine.

Prepare fuel system for storage:

Drain all gasoline from the tank and
carburetor. This is most easily accomplished by
running the pressure washer with the high
pressure hose
until the engine stops from lack
of fuel.

Add fuel stabilizer to the gasoline (following
manufacturer's instructions)
Fuel stabilizer steps:
a.
Ensure gas tank is full.

c. Run pressure washer with high
pressure hose
at least 5 minutes after
adding stabilizer to allow it to enter the
fuel system.
d. Shut off engine
2. Lubricate cylinder and piston:
a.
Disconnect spark plug wire and remove spark
plug
b. Add one teaspoon oil through spark plug hole
c. Place rag over spark plug hole and slowly pull
the recoil a few times to lubricate the
combustion chamber.
Replace spark plug, but do not reconnect the spark
plug wire.
