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 discharge nipple on
machine.
Connect high pressure hose to injector with quick cou-
pler. (Check to make sure locking coupler sleeves are
in proper position before applying water pressure).
STEP 2:
Use detergent designed
specifically for pressure wash-
ers. Household detergents could
damage the pump. Prepare deter-
gent 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:
With safety latch on
spray gun engaged, secure black
detergent nozzle into quick cou-
pler.
NOTE:
Detergent cannot be
applied using red, yellow, green or
white nozzles.
STEP 4:
With the engine running, pull trigger to op-
erate machine. Liquid detergent is drawn into the ma-
chine 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.
IMPORTANT: The instructions on this page pertain
to the pressure washer used in connection with
model HS-3000.
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 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
washing.
CAUTION - Never use:
• Bleach, chlorine 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
damage 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.
