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.

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 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.

STEP 9: 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.

DETERGENTS & GENERAL CLEANING TECHNIQUES

PRESSURE WASHER

WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe nau­sea, fainting or poisoning. The
harmful elements may cause
propert y 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).

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
pump protector engages and cools the pump by dis­charging the warm water onto the ground. This thermal
device prevents internal damage to the pump.

OPERATOR’S MANUAL

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.

STEP 2: 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 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.

97-707 • BG • REV. 7/06

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 pressure washing.

CAUTION - Never use:

• Bleach, chlorine 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 the
detergent siphon tube from bottle.

STEP 1: Remove detergent suc-

STEP 2: Turn off the engine. STEP 3: Turn off wa-

for one minute.

OPERATOR’S MANUAL

STEP 4: Press trigger

to release water pres­sure.

STEP 5: Disconnect the gar­den hose from the water inlet
on the machine.

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

STORAGE

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 main­tenance of the engine.
