DETERGENTS AND GENERAL OPERATING TECHNIQUES
WARNING: Some detergents
WARNING
may be harmful if inhaled or in-
gested, causing severe nausea,
fainting or poisoning. The harm-
ful elements may cause property
damage or severe injury.
STEP 1: 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 pres-
sure 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: De-
tergent cannot be applied using the Yellow nozzle.
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.
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

STEP 3: With the engine run-
ning, pull trigger to operate ma-
chine. Liquid detergent is
drawn into the machine and
mixed with water. Apply deter-
gent to work area. Do not al-
low detergent to dry on surface.

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 sur-
face at low pressure (for best results, limit your work area to
sections approximately 6 feet square and always apply de-
tergent from bottom to top). Allow detergent to remain on
surface 1-3 minutes. Do not allow detergent to dry on sur-
face. If surface appears to be drying, simply wet down sur-
face with fresh water. If needed, use brush to remove stub-
born dirt. Rinse at high pressure from top to bottom in an
even sweeping motion keeping the spray nozzle approxi-
mately 1 foot from cleaning surface. Use overlapping strokes
as you clean and rinse any surface. For best surface clean-
ing 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 to pressure washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinners,
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 de-
tergent siphon tube from bottle.
