PRESSURE WASHER OPERATOR’S MANUAL
OPERATING INSTRUCTIONS
STEP 1: Check engine oil level. Oil level should be level with the bottom
of the oil filler neck. Be sure the machine is level when checking the oil
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.
STEP 4: Connect garden hose
to the cold water source and turn
water on completely. Never use
hot water.
STEP 6: Slide the fuel valve lever to the "ON" position.
When the engine is not in use, leave the fuel valve in
the "OFF" position.
STEP 5: Trigger the spray gun to
eliminate trapped air then wait for
a steady flow of water to emerge
from the spray nozzle.
STEP 3: Fill gas tank with unleaded
gasoline. Do not use leaded gaso-
line.
STEP 7: Move the choke lever to the "Choke" posi-
tion (on a warm engine, leave the choke lever in the
run position).

STEP 8: Turn the engine switch to "On" position.
On Vanguard engines, move the throttle lever to
"Fast" position, shown on the engine as a rabbit.
STEP 9: Pull the starter grip. If the engine fails to start
after 2 pulls, squeeze the trigger gun to release pres-
sure and repeat step. Return starter gently. After the
engine warms up enough to run smoothly, move choke
to run position and throttle to fast position.
CAUTION: Small engines may kick back. Do not
hold pull starter grip tightly in hand.
OPERATING INSTRUCTIONS
WARNING! Never replace
nozzles without engaging the
safety latch on the spray gun
trigger. The four color-coded quick connect nozzles provide a wide array of
spray widths from 0° to 40° and are easily accessible when placed in the
convenient rubber nozzle holder, which is provided on the front of the
machine.
NOTE: For a more gentle rinse, select the white 40° or green 25° nozzle.
To scour the surface, select the yellow 15° or red 0° nozzle. To apply
detergent select the black nozzle. (Detergent injector and black nozzle
not included)

PRESSURE WASHER OPERATOR’S MANUAL
WARNING: Some detergents
may be harmful if inhaled or in-
gested, causing severe nausea,
fainting or poisoning.The harm-
ful elements may cause property
damage or severe injury.
STEP 1: Connect the optional
detergent injector to discharge nipple on machine. Con-
nect high pressure hose to injector with quick coupler.
(Check to make sure locking coupler sleeves are in
proper position before applying water pressure).
STEP 2: Use detergent designed specifically for pres-
sure washers. Household detergents
damage the pump. Prepare detergent
solution as required by manufac-
turer. 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.

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 tempera-
tures. When the water reaches this temperature, the
pump protector engages and cools the pump by dis-
charging the warm water onto the ground.This thermal
device prevents internal damage to the pump.
CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place de-
tergent 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 al-
low 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 sweep-
ing 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.
Recommendations:
• 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 dam-
age 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.

PRESSURE WASHER OPERATOR’S MANUAL
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 trig-
ger 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 in-
dicates 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 con-
tainer.
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.

national codes, it cannot be responsible for how the customer chooses to use or install the product. Some states do not al-
low limitations on how long an implied warranty lasts or the exclusion or limitation of incidental or consequential damages,
so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights and you may also
have other rights which vary from state to state.
