O–Ring Maintenance

Through the normal operation of your pressure washer,
o–rings, which keep the connections of the hoses and spray
gun tight and leak–free, may become worn or damaged.
An O–Ring Maintenance Kit is provided with your pressure
washer. It 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 UNITFOR 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. Flush for one to two minutes.
2. Shut off the engine and let it cool, then remove all
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 PumpSaver to treat pump. This prevents freeze
damage and lubricates pistons and seals.
NOTE: If PumpSaver is not available, draw RV antifreeze
(non-alcohol) into the pump by pouring the solution into a
3-foot section of garden hose connected to inlet adapter
and pulling recoil handle twice.
5. Store unit in a clean, dry area.
STORING THE ENGINE
See the engine owner’s manual for instructions on how to
properly prepare the engine for storage.
