Prepare engine for
long term storage
(if storing more than
30 days)
Storage
3. Using a wrench, disconnect the plumbing that connects to the heating
coil inlet. The water will flow out of the heating coil. This will protect
the coil from freeze damage.
4. Open both water inlet ball valves and remove the cap from the water
filter. This will drain the pump and water inlet plumbing.
Long Term freeze protection: (if storing more than 30 days)
The RV antifreeze will save the components from freeze damage and keep
them lubricated.
1. Fill attached feed tank or a separate bucket with 5 gallons of RV
antifreeze.
a. If feed tank has been used, drain water from it first.
b. If using a bucket, submerge one end of a short garden hose in the
bucket and connect the other end to the water supply inlet on the
pump.)
2. Disconnect the high pressure hose from the high pressure water outlet.
3. Run the engine (with burner off) until RV antifreeze comes out of the
high pressure water outlet.
4. Make sure excess antifreeze is disposed of safely.
First prepare the engine for long term storage if you will not be using
the pressure washer again 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.
1. Prepare fuel system for storage:
o 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.
OR
o Add fuel stabilizer to the gasoline (following manufacturer's
instructions)
Fuel stabilizer steps:
a. Ensure gas tank is full.
b. Add fuel stabilizer to fuel tank.
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 turn starter (or pull the recoil) a
few times to lubricate the combustion chamber.
d. Replace spark plug, but do not reconnect the spark plug wire.
