PREPARATION FOR STORAGE
It is recommended that you follow these steps to
protect the internal seals of the pressure washer when
storing the unit for an extended period and WHEN
FREEZING TEMPERATURES ARE EXPECTED.
ENGINE
1. Remove gasoline from engine or add fuel stabi-
lizer, such as "Sta-Bil" to gasoline to prevent
gumming
2. If you are adding fuel stabilizer, connect water
supply and high pressure hose to pump and spray
gun.
3. Turn water supply on and start engine.
4. Squeeze spray gun trigger while engine is running
to avoid operating pump in ""bypass mode"".
5. Run engine for five minutes, then shut engine off.
6. Disconnect water supply.
7. Disconnect spark plug wire and remove spark
plug.
8. Pour one teaspoon of engine oil into spark plug
hole.
9. Place a rag over the spark plug hole and pull
starter rope slowly several times to lubricate
internal cylinder wall.
PUMP
NOTE: If storing the unit for more than 30 days
RV antifreeze needs to be ran through the
pump. This helps prevent damage within the
pump head. RV antifreeze is not only added for
winterizing, but for proper lubrication regard-
less of temperature or environment. Storing the
pump less than 30 days does not require the
RV antifreeze.
1. Obtain a funnel, six ounces of RV antifreeze, and
approximately 12 inches of garden hose with a
male hose connector attached to one end.
Use only RV antifreeze. Any other anti-
freeze is corrosive and can damage pump.
2. Disconnect high pressure hose from pump and
from spray gun.
3. Connect 12 inch length of hose to water inlet of
pump.
4, Add RV antifreeze to hose as shown.
5. Pull engine starter rope slowly several times until
antifreeze comes out of high pressure hose
connection of pump.
6. Remove short hose from water inlet of pump.
7. Install spark plug into spark plug hole and tighten
securely, then reconnect spark plug wire.
8. Drain all water from high pressure hose, coil it, and
store it in cradle of pressure washer handle.
9. Drain all water from spray gun and wand by
holding spray gun in a vertical position with nozzle
end pointing down and squeezing trigger. Store in
cradle on pressure washer handle.
10. Store nozzles in color matching receptacles on flat
panel of pressure washer handle.
11. Store chemical hose, high pressure hose, spray
gun, and wand so they are protected from dam-
age, such as being run over.
