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 chemical injector hose by placing the injector
filter into a pail of clean water while running
pressure washer and squeezing the spray gun
trigger with the dual lance in low pressure mode.
Flush for two minutes.
2.Shut off the engine and let it cool, then remove all
hoses.
3.Place Run/Stop Switch in STOP position.
4.Empty the pump of all 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 R. V. Antifreeze (Antifreeze without alcohol) into
pump by pouring antifreeze 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
Using a fuel additive such as STA-BIL®, or
equivalent, will prevent the build up of gum and
varnish in the fuel system. Refer to the engine
owners manual for further information.
