DETERGENTS AND GENERAL OPERATING TECHNIQUES
WARNING
STEP 1: Connect detergent injector to discharge nipple
on machine. Connect high pressure hose to injector
with quick coupler. (Check to make sure locking cou-
pler sleeves are in proper position before applying water
pressure).

STEP 4: With the motor 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 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.

WARNING: Some detergents may
be harmful if inhaled or in-
gested, causing severe nausea,
fainting or poisoning. The harm-
ful elements may cause prop-
erty damage or severe injury.

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 pres-
sure 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 deter-
gent nozzle into quick coupler.
NOTE: Detergent cannot be ap-
plied using a pressure nozzle.

THERMAL PUMP PROTECTION
If you run the motor 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 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 remov-
ing detergent siphon tube from bottle.
