WARNING: Some detergents
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:
Connect the optional
detergent injector to discharge nipple on machine. Con-
nect 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 pres-
sure washers. Household detergents
damage the pump. Prepare detergent
solution as required by manufac-
turer. Fill a container with pressure
washer detergent. Place filter end of
detergent suction tube into 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 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.

THERMAL PUMP PROTECTION
If you run the engine on your pressure washer for 1-2
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 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 al-
low 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 sweep-
ing 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 to pressure washing.
CAUTION - Never use:
• Bleach, chlorine products 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 detergent
siphon tube from bottle.
