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 lock-
ing couplers are in proper position before applying
water pressure).
STEP 2: Use detergent designed
specifically for pressure wash-
ers. Household detergents could
damage the pump. Prepare de-
tergent 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 run-
ning, pull trigger to operate ma-
chine. 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.
*Kit Injector sold separately.
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 tempera-
ture, 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.
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 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.

SHUTTING DOWN AND CLEAN-UP
STEP 1: Remove detergent suc-
tion tube from container and insert
into one gallon of fresh water. Slide
nozzle forward for low pressure or to
connect black detergent nozzle into
wand quick coupler. Pull trigger on
spray gun and siphon water for one
minute.
STEP 2: Turn off the engine. STEP 3: Turn off wa-
ter supply.
STEP 5: Disconnect the gar-
den hose from the water inlet
on the machine.
STEP 6: Disconnect the high
pressure hose from high pres-
sure outlet.
STEP 7: Engage the
spray gun safety lock.
STEP 4: Press trigger
to release water pres-
sure.
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 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 main-
tenance of the engine.

Unloader Adjustment Procedures
1. Remove lock nut (Item 19).
2. Remove adjustment knob (Item 24).
3. Loosen the two (2) nuts (Item 20), move them upward on stem (Item 3) until you see 4 or more threads below the nut.
4. Re-attach adjusting knob (Item 24).
5. Start machine. Open the trigger of the spray gun. Increase pressure by turning adjustment knob (Item 24) clockwise until
pressure is at the desired operating pressure.
6. Remove the adjustment knob (Item 24), tighten the lower nut (Item 20) tightly against the upper nut (Item 20). Re-attach
adjustment knob (Item 24) and screw down until contact is made with the nuts (Items 20). Screw down lock nut (Item
19) onto the stem (Item 3) until the threads cut into the nylon insert of the lock nut (Item 19).
*If adjustment knob (Item 24) DOES NOT make contact with upper nut (Items 20), remove adjusting knob (Item 24), re-adjust
(raise) nuts (Items 20) on stem (Item 3) and re-attach adjustment knob (Item 24), then repeat step #6.
**If adjustment knob (Item 24) DOES make contact with upper nut; release the trigger of the spray gun and watch the pres-
sure gauge for the pressure increase (“spike”).
This “spike” SHOULD NOT exceed 500 psi above the operating pressure. If
“spike” pressure exceeds the 500 psi limit, remove the adjusting knob (Item 24) and re-adjust (lower) the nuts (Items 20) on
the stem (Item 3). Re-attach the adjusting knob (Item 24), then repeat step #6.
