PRESSURE WASHER

WARNING: Some detergents may
be harmful if inhaled or ingested,
causing severe nausea, fainting
or poisoning. The harmful ele-
ments may cause property dam-
age 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
pressure washer detergent. Place
the filter end of detergent suction
tube into the detergent container.
STEP 3: With safety latch on spray gun engaged, se-
cure 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 deter-
gent 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 min-
utes.
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 deter-
gent 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 dis-
tance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use ex-
treme caution as pressure washer may remove the
loose paint from the surface.
• Keep the spray nozzle a safe distance from the sur-
face you plan to clean. High pressure wash a small
area, then check the surface for damage. If no dam-
age is found, continue pressure washing.
CAUTION - Never use:
• Bleach, chlorine and other corrosive chemicals
• Liquids containing solvents (i.e., paint thinner, gaso-
line, 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 deter-
gent siphon tube from bottle.
