PRESSURE WASHER OPERATOR’S MANUAL
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 3: Connect garden hose
to the cold water source and turn
water on completely. Never use
hot water.
STEP 5: Rotate the fuel shut-off valve to the "On"
position. 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 4: Trigger the spray gun to
eliminate trapped air then wait for a
steady flow of water to emerge from
the spray nozzle.
OPERATING INSTRUCTIONS
STEP 2: Fill gas tank with unleaded
gasoline. Do not use leaded gas-
oline.
STEP 6: Pull the choke knob out to the "Choke" position
(on a warm engine, when in the run position, leave the
choke knob in). Push the choke knob to the "Closed"
position.To restart a warm engine, leave the choke knob
in the "Open" position.

STEP 7: Turn the engine switch to "ON" position. STEP 8: Pull the starter grip. If the engine fails to start
after 2 pulls, squeeze the trigger gun to release pressure
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 (CON'T)
WARNING! Never replace
nozzles without engaging the
safety latch on the spray gun
trigger.
The five color-coded quick connect
nozzles provide a wide array of spray
widths from 0° to 45° and are easily ac-
cessible 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.

PRESSURE WASHER OPERATOR’S MANUAL
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 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 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.
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 thinners,
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 hose from bottle.
WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe nau-
sea, fainting or poisoning. The
harmful elements may cause
property damage or severe
injury.
STEP 1: Connect 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).
STEP 2: Use detergent designed
specifically for pressure washers.
Household detergents could dam-
age the pump. Prepare detergent
solution as required by the manu-
facturer. Fill a container with pres-
sure washer detergent. Place the
filter end of detergent suction hose
into the detergent container.
STEP 3: With safety latch on spray gun engaged,
secure black soap 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 hose
into a bucket of clean water, then run the pressure
washer in low pressure for 1-2 minutes.

SHUTTING DOWN AND CLEAN-UP
STEP 1: Remove detergent suction
tube from container and insert into
one gallon of fresh water. Slide nozzle
forward for low pressure or to connect
black detergent nozzle. Pull trigger
on spray gun and siphon water for
one minute.
STEP 2: Turn engine switch to "OFF"
position.
STEP 3: Turn off water
supply.
STEP 5: Disconnect the garden
hose from the water inlet on the
machine.
STEP 6: Disconnect the high
pressure hose from the dis-
charge nipple.
STEP 7: Engage
the spray gun safety
lock.
STEP 4: Press trig-
ger to release water
pressure.
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
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 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.
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.
