O-RING MAINTENANCE
Provided with your pressure washer is an O–Ring
Maintenance Kit which includes replacement o-rings,
rubber washer and water inlet filter. Refer to the
instruction sheet provided in the kit to service your
unit’s o-rings. Note that not all of the parts in the kit
will be used on your unit.

Monitoring the pump oil level is the only pump
maintenance item performed by the owner. If the
pump oil level drops below the “ Add ” mark on the oil
dipstick, slowly add SAE 20-30W oil to the “ Full ” mark.

PREPARING UNIT FOR
STORAGE
Water should not remain in the unit for long periods of
time. Sediments of minerals can deposit on pump
parts and “freeze” pump action.
If you do not plan to use the pressure washer for more
than 30 days, follow this procedure:
1. Flush chemical injection tube by placing the filter
into a pail of clean water while running pressure
washer with the black chemical nozzle. Flush for
one to two minutes.
2. Shut off the engine and let it cool, then remove all
hoses.
3. Move the throttle lever to the “ SLOW ” position.
4. Set engine switch to the “ OFF ” position.
WARNING!
Be sure switch is in “ OFF ” position
before you continue. If you start engine without
proper water supply connected, you can
damage pump.
5. Empty the pump of all pumped liquids by pulling
the recoil handle about 6 times. This should
remove most of the liquid in the pump.
NOTE: To protect the unit from freezing temperatures,
draw RV antifreeze (no alcohol) into the pump by
pouring the antifreeze into a 3–foot section of garden
hose connected to inlet adapter and pulling recoil
handle twice. This process is also recommended to
avoid lime/calcium build-up in the pump during longer-
term storage.
6. Store in a clean, dry area.
STORING THE ENGINE
