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.
STEP 1: Connect detergent in-
jector 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 pres-
sure washers. Household detergents
could damage the pump. Prepare
detergent solution as required by
manufacturer. 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 injec-
tion system after each use by placing the suction
tubeinto 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
temperatures. When the water reaches this tempera-
ture, the pump protector engages and cools the pump
by discharging 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 wash-
ing.
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.
