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.
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.
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.
Preventative Maintenance
1.
Check to see that the water pump is properly
lubricated.
2.
Follow winterizing procedures to prevent freeze
damage to the pump and coils.
3.
Always neutralize and flush detergent from system
after use.
4.
If water is known to be high in 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 Landa cleaning
products.
7.
Never run pump dry for extended periods of time.
8.
Use clean fuel-kerosene, No. 1 fuel oil or diesel.
Replace fuel filter every 100 hours of operation.
Avoid water contaminated fuel as it will seize up
the fuel pump.
9.
If machine is operated with smoking or eye burning
exhaust, coils will soot up, not letting water reach
maximum operating temperature. (See section on
Air Adjustments.)
10. Never allow water to be sprayed on or near engine
or burner assembly or any electrical component.
11. Periodically delime coils as per instructions.
12. Check to see that engine is properly lubricated.
It is advisable, periodically, to visually inspect the
burner. Check air inlet to make sure it is not clogged or
blocked. Wipe off any oil spills and keep this equipment
clean and dry.
The areas around the pressure washer should be kept
clean and free of combustible materials, gasoline and
other flammable vapors and liquids.
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner.
