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.
An O–Ring Maintenance Kit is provided with your
pressure washer 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.
WARNING: The high pressure stream of water that
this equipment produces can pierce skin and its
underlying tissues, leading to serious injury and
possible amputation.
• NEVER repair leaking connections with sealant of
any kind. Replace o-ring or seal.
Pump Maintenance
This model does not require any pump
maintenance. The pump is pre-lubricated and
sealed, requiring no additional lubrication for the life
of the pump.
Engine Maintenance
See the engine operator’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 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. 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. Draw RV antifreeze (non-alcohol) into the pump
by pouring the solution into a 1 M (3 FT) section
of garden hose connected to inlet adapter and
pulling recoil handle twice.
If available, use PumpSaver in place of RV
antifreeze and follow package instructions.
5. Store unit in a clean, dry area.
Storing the Engine
