spray gun tight and leak–free, 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
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.

PREPARING THE UNIT

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 high
pressure and garden hoses. Disconnect spark plug wire
from spark plug.
3.
Empty the pump of liquids by pulling the engine recoil
handle about 6 times. This should remove most of the
liquid in the pump.
4.
Use pump saver to prevent corrosion build up and
freezing of pump.
5.
Store unit in a clean, dry area.
Protecting the Pump
To protect the pump from damage caused by mineral
deposits or freezing, use PumpSaver to treat pump. This
prevents freeze damage and lubricates pistons and seals.
NOTE: PumpSaver, model number 01559, is available as an
optional accessory. It is not included with the pressure washer.
CAUTION
You must protect your unit from freezing temperatures.
• Failure to do so will permanently damage your pump and
render your unit inoperable.
• Freeze damage is not covered under warranty.
CAUTION
Read and follow all cautions and warnings on the
PumpSaver can label.
• Always wear eye protection when using PumpSaver.
To use PumpSaver, make sure the pressure washer is
turned off and disconnected from supply water. Read and
follow all instructions and warnings given on the
PumpSaver container.
NOTE: PumpSaver will drip from pump after treatment
and will stain wood and concrete.
NOTE: If PumpSaver is not available, 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.
STORING THE ENGINE
