PRESSURE WASHER
OPERATOR’S MANUAL
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.
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 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 wa-
ter, 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 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
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.
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 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 the
detergent siphon tube from bottle.
