WARNING
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: Use detergent designed
specifically for pressure wash-
ers. Household detergents could
damage the pump. Prepare deter-
gent 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 2: Apply safety latch to spray gun trigger.
Secure black detergent nozzle into quick coupler. NOTe:
Detergent cannot be applied using the Yellow nozzle.
STep 3: Selection of high or low pressure is accom-
panied by turning the handle. NOTe: High pressure
nozzle must be inserted at end of wand to obtain high
pressure. To apply soap connect detergent injector
to discharge nipple and secure by pushing coupler
collar forward. Turn handle to lower pressure (water
will exit both nozzles). Place detergent pick-up tube
into detergent container. Rinse by turning handle for
high pressure.
STep 4: With the engine run-
ning, pull trigger to operate
machine. Liquid detergent is
drawn into the machine and
mixed with water. Apply deter-
gent to work area. Do not allow

detergent to dry on surface.
IMPORTANT: You must flush the detergent injec-
tion 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 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.
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
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.
Recommendations:
• Before cleaning any surface, an inconspicuous

• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will
damage the surface being cleaned.
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.
