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.

properly maintain the engine.
PREPARING 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 chemical injection tube by placing the filter into a
pail of clean water while running pressure washer in
low pressure (adjustable nozzle in forward position).
Flush for one to two minutes.
2. Shut off the engine and let it cool, then remove all
hoses.
WARNING!
before you continue. If you start engine without
proper water supply connected, you can damage
pump.
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 (no alcohol) into the pump by pouring
the antifreeze into a 3–foot section of garden hose
connected to inlet adapter and pulling recoil handle twice.
4. Store in a clean, dry area.
