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 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 pressure washers.
Prepare detergent solution as
required by the manufacturer. Fill
a container with pressure washer
detergent. Place the filter end of
detergent suction tube into the
detergent container.
STEP 3: Apply safety latch to
spray gun trigger. Turn variable pressure control handle
until discharge water exits both tubes. Secure black
detergent nozzle into quick coupler if you have a single
wand.
NOTE: Detergent cannot be applied using Red,
Yellow, Green or White nozzles.
STEP 3: With the engine run-
ning, pull trigger to operate ma-
chine. 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 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 or 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 removing
detergent siphon tube from bottle.
