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 injector to high pressure
outlet 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
specifi cally 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
fi lter 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 red, yellow, green or
white nozzles.
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 fl ush 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
PROTECTOR
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
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 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 fl owing by simply removing detergent
siphon tube from bottle.
