Maintenance
Storage
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.
ATTENTION: Toujours entreposer la laveuse à
pression dans un endroit où la température ne sera
pas inférieure à 0°C (32 °F). La pompe sur cette
machine est susceptible de subir des dommages si
elle est exposée au gel.
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
remaining 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.
ATTENTION: Le non-respect des directives ci-
dessus entraînera des dommages à la laveuse à
pression.
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 pressure washer and store in a clean, dry
place that is well ventilated away from open flame
or sparks. NOTE: Use of a fuel additive, such as
STA-BIL
®
, or an equivalent, will minimize the
formulation of fuel deposits during storage. 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.
ATTENTION: Avant de redémarrer, faire fondre la
glace se trouvant sur les boyaux, le pistolet
pulvérisateur ou la lance de la laveuse à pression.
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.
Preventative Maintenance
1. Check to see that water pump is properly lubri-
cated.
2. Follow winterizing instructions to prevent freeze
damage to pump and coils.
3. Always neutralize and flush detergent from system
after use.
4. If water is known to have high mineral content, use
a water softener in your water system, or de-scale
as needed.
5. Do not allow acidic, caustic or abrasive fluids to be
pumped through system.
6. Always use high grade quality cleaning products.
7. Never run pump dry for extended periods of time.
8. Use clean fuel: kerosene, No. 1 fuel oil, or diesel.
Clean or replace fuel filter every 100 hours of oper-
ation. Avoid water contaminated fuel as it will
damage the fuel pump.
9. If machine is operated with smoky or eye burning
exhaust, coils will soot up, not letting water reach
maximum operating temperature.
10. Never allow water to be sprayed on or near engine
or burner assembly or any electrical component.
11. Periodically descale coils as per instructions.
12. Check to see that engine is properly lubricated.
