O-RING MAINTENANCE
O-rings keep the connections of the hoses and spray gun
tight and leak-free. Through the normal operation of your
pressure washer, 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.
PREPARING THE 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 detergent siphon tube by placing the siphon tube
filter into a pail of clean water while running pressure
washer with nozzle in low pressure mode. Flush for
five minutes.
2.
Shut off the engine and let it cool, then remove all
hoses.
3.
Place governor control lever in “Stop” position.
CAUTION!
Be sure lever is in “Stop” position
before you continue. If you start engine without
proper water supply connected, you can damage
pump.
4.
Empty the pump of all pumped liquids by pulling recoil
handle about 6 times. This should remove most of the
liquid in the pump.
NOTE: To protect unit from freezing temperatures, draw
windshield washer fluid into pump by pouring windshield
washer fluid into a 3-foot section of garden hose
connected to inlet adapter and pulling recoil handle twice.
5.
Store in a clean, dry area.
STORING THE ENGINE
See the engine owner’s manual for instructions on how to
