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.
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 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.
Storing the Engine
