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 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. Se-
cure black detergent nozzle into quick coupler. NOTE:
Detergent cannot be applied using the Yellow nozzle.
STEP 3: With the motor run-
ning, pull trigger to operate
machine. 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 sur-
face.
IMPORTANT: You must flush the detergent injec-
tion system after each use by placing the suction
tube into a bucket of clean water, then run the pres-
sure washer in low pressure for 1-2 minutes.
THERMAL PUMP
PROTECTION
If you run your pressure washer for 3-5 minutes with-
out pressing the trigger on the spray gun, circulating
water in the pump can reach high temperatures. When
the water reaches this temperature, the pump protec-
tor engages and cools the pump by discharging the
warm water onto the ground. This thermal device pre-
vents 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
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
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 wash-
ing.
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.
