O-Ring Maintenance

Your pressure washer uses o-rings to keep hose and spray
gun connections tight and leak-free. Through the normal
operation of your unit, 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 not all of the parts in the kit will be used
on your unit.
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.
OIL CHANGE NOTE: It is necessary to tip your
pressure washer when changing engine oil. Avoid spilling oil
on pump when changing engine oil. Wipe up any spilled oil
promptly.
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 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.
NOTE: To protect the unit from freezing temperatures,
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.
4. Store unit in a clean, dry area.
