O–Ring Maintenance
Through the normal operation of your pressure washer,
o–rings are used to keep the connections of the hoses and
spray gun tight and leak–free. These o-rings may become
worn or damaged.
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 you will not use all of the parts in the
kit.
To remove a worn or damaged o–ring:
• Use a small flathead screwdriver to get underneath the
o-ring and pry it off.
ENGINE MAINTENANCE
See the engine owner’s manual for instructions on how to
properly maintain the engine.
CAUTION!
Avoid prolonged or repeated skin
contact with used motor oil. Used motor oil has
been shown to cause skin cancer in certain
laboratory animals. Thoroughly wash exposed areas
with soap and water.
KEEP OUT OF REACH OF CHILDREN. DON'T
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.
PREPARING THE UNIT
FOR STORAGE
Water should not remain in the unit for long periods of
time. Sediments or 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 detergent siphoning tube by placing the filter into
a pail of clean water while running pressure washer in
low pressure mode (adjustable nozzle in the forward
position). Flush for one to two minutes.
2.
Shut off the engine and let it cool, then remove high
pressure and garden hoses. Disconnect spark plug wire
from spark plug.
3.
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.
4.
Use Generac brand PumpSaver to prevent corrosion
build up and freezing of pump.
5.
Store unit in a clean, dry area.
