level. (Refer to the engine's operating manual included with machine.)
We recommend that the oil be changed after the first 5 hours of use, then
once every 50 hours. Note: Improper oil levels will cause low oil sensor
to shut off engine. IMPORTANT! Do not run engine with high or low
oil levels as this will cause engine damage.
STEP 2: Remove shipping cap and
install oil dipstick. Check pump oil
level by using dipstick or observe
oil level in oil window (if equipped).
Use 40 wt. non detergent oil.

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 always 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 dirt. 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 strokes
as you clean and rinse any surface. For best surface
cleaning action spray at a slight angle.
OPERATOR’S MANUAL
STEP 1: Connect the optional detergent injector to
discharge nipple on machine. Connect high pressure
hose to injector with quick coupler. (Check to make
sure locking coupler sleeves are in proper position
before applying water pressure).
THERMAL PUMP PROTECTION
If you run the engine on your pressure washer for 1-2
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
pump protector engages and cools the pump by discharging the warm water onto the ground. This thermal
device prevents internal damage to the pump.
PRESSURE WASHER
DETERGENT AND GENERAL CLEANING TECHNIQUES
Recommendations:
STEP 2: Use detergent designed
specifically for pressure washers.
Household detergents could damage the pump. Prepare detergent
solution as required by manufacturer. Fill a container with pressure
washer detergent. Place filter end of
detergent suction tube into detergent
container.
STEP 3: With safety latch on spray
gun engaged, secure black detergent
nozzle into quick coupler. NOTE:
Detergent cannot be applied using
red, yellow, green or white nozzles.
STEP 4: 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.
IMPORTANT: You must 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.
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use
extreme caution as pressure washer may remove
the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
surface you plan to clean. High pressure wash a
small area, then check the surface for damage. If
no damage is found, continue to pressure washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinner,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will damage the surface being cleaned.
RINSING
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Remove 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.

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:
12
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: 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 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 maintenance of the engine.
