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 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 de-
tergent nozzle into quick coupler.
NOTE: Detergent cannot be applied
using a pressure nozzle.
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
ingested, causing severe nau-
sea, fainting or poisoning. The
harmful elements may cause
property damage or severe
injury.

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.
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' 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' from cleaning surface. Use over-
lapping 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 dam-
age. If no damage is found, continue to pressure
washing.
CAUTION - Never use:
• Bleach, chlorine products or 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.
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.
