DETERGENTS AND GENERAL OPERATING TECHNIQUES
WARNING
PRESSURE W ASHER
OPERATOR’S MANUAL
STEP 2: Apply safety latch to spra y gun trigger. Secure
black detergent nozzle into quick coupler. NOTE: Detergent cannot be applied using the Yellow nozzle.
WARNING: Some detergents
may be harmful if inhaled or ingested, causing severe nausea,
fainting or poisoning. The harmful elements may cause property
damage or severe injury .
STEP 1: Use detergent designed
specifically for pressure washers.
Household detergents could damage the pump. Prepare detergent
solution as required by the manufacturer . Fill a container with pressure washer detergent. Place the
filter end of detergent suction tube
into the detergent container.
STEP 3: With the engine running, pull trigger to operate machine. Liquid detergent is
drawn into the machine and
mixed with water . Apply detergent to work area. Do not allow detergent to dry on surface.
pump protector engages and cools the pump by discharging the warm water onto the ground. This thermal
device prev ents internal damage to the pump .
CLEANING TIPS
Pre-rinse cleaning surface with fresh water . Place detergent
suction tube directly into cleaning solution and apply to surface at low pressure (for best results , limit your work area to
sections approximately 6 feet square and alw a ys apply detergent from bottom to top). Allow detergent to remain on
surface 1-3 minutes. Do not allow detergent to dry on surface. If surface appears to be drying, simply wet down surface with fresh water . If needed, use brush to remove stubborn dir t. Rinse at high pressure from top to bottom in an
even sweeping motion keeping the spray nozzle approximately 1 foot from cleaning surface . Use overlapping strok es
as you clean and rinse any surface. For best surface cleaning action spray at a slight angle.
Recommendations:
• Before cleaning any surf ace, an inconspicuous area
should be cleaned to test spray pattern and distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use e xtreme caution as pressure washer may remo ve the
loose paint from the surface.
• Keep the spr ay nozzle a saf e distance from the surface you plan to clean. High pressure wash a small
area, then check the surface f or damage. If no damage is found, continue to pressure washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
These chemicals will harm the machine and will damage the surface being cleaned.
RINSING
IMPORT ANT : You m ust flush the detergent injection
system after each use by placing the suction tube
into a bucket of clean water, then run the pressure
washer in low pressure for 1-2 minutes.
THERMAL PUMP PROTECTION
If you run the engine on your pressure washer for 3-5
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach high temperatures. When the water reaches this temperature, the

• It will take a f ew seconds f or the detergent to clear .
Apply safety latch to spray gun. Remov e black soap
nozzle from the quick coupler . Select and install the
desired high pressure nozzle. NOTE: You can also
stop detergent from flowing by simply removing detergent siphon tube from bottle.

CAUTION: Al wa ys store y our 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

1. Stop the pressure washer, squeeze spra y 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 . T urn 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 follo w 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 intak e and exhaust valves to pre v ent rusting of cylinder.
4. Cover the pressure washer and store in a clean, dry
place that is well ventilated awa y 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 gasolinee 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 atmosheric conditions may
develop which will cause an icing condition in the carb uretor. If this develops, the engine may run rough, lose
power and may stall. This temporar y condition can be
overcome b y deflecting some of the hot air from the engine over the carburetor area. NOTE: Refer to the engine manufacturer's manual f or service and maintenance
of the engine.
