PRESSURE WASHER

SHUTTING DOWN AND CLEAN-UP
CAUTION: Always store your pressure washer in a
location where the temperature will not fall below
32°F (0°C). The pump in this machine is susceptible
to permanent damage if frozen. FREEZE DAMAGE
IS NOT COVERED BY WARRANTY.
1. Stop the pressure washer, squeeze spray gun
trigger to release pressure.
2. Detach water supply hose and high pressure
hose.
3. Turn on the machine for a few seconds, until re-
maining water exits. Turn engine off immediately.
4. Drain the gas and oil from the engine.
5. Do not allow high pressure hose to become
kinked.
6. Store the machine and accessories in a room
which does not reach freezing temperatures.
CAUTION: Failure to follow the above directions
will result in damage to your pressure washer.
When the pressure washer is not being operated or is
being stored for more than one month, follow these
instructions:
1. Replenish engine oil to upper level.
2. Drain gasoline from fuel tank, fuel line, fuel valve
and carburetor.
3. Pour about one teaspoon of engine oil through
the spark plug hole, pull the starter grip several
times and replace the plug. Then pull the starter
grip slowly until you feel increased pressure which
indicates the piston is on its compression stroke
and leave it in that position. This closes both the
intake and exhaust valves to prevent rusting of
cylinder.
4. Cover the pressure washer and store in a clean, dry
place that is well ventilated away from open flame
or sparks.
NOTE:
The use of a fuel additive, such
as STA-BIL
®
, or an equivalent, will minimize the
formulation of fuel deposits during shortage. Such
additives may be added to the gasoline in the fuel
tank of the engine, or to the gasoline in a storage
container.
After Extended Storage
CAUTION: Prior to restarting, thaw out any
possible ice from pressure washer hoses,
spray gun or wand.
Engine Maintenance
During the winter months, rare atmospheric conditions
may develop which will cause an icing condition in the
carburetor. If this develops, the engine may run rough,
lose power and may stall. This temporary condition can
be overcome by deflecting some of the hot air from the
engine over the carburetor area.
NOTE:
Refer to the
engine manufacturer’s manual for service and mainte-
nance of the engine.
STORAGE
STEP 1:
If using an op-
tional detergent injector,
place the detergent line in
a bucket of water allowing
detergent to be flushed
from system.
STEP 2:
Turn burner
switch off and continue
spraying water, allowing
the water to cool. After
water has cooled to less
than 100°F, turn the at-
tached pressure washer
off.
STEP 3:
Turn garden hose
water off. Open the spray
gun to relieve remaining
pressure.
