Detergents & General Cleaning
Techniques
WARNING: Some detergents may
WARNING
be harmful if inhaled or ingested,
causing severe nausea, fainting
or poisoning. The harmful
elements may cause property
damage or severe injury.
STEP 1: Use detergent designed
specifically for pressure washers.
Household detergents could damage
the pump. Prepare detergent
solution as required by the manufac-
turer. Fill a container with pressure
washer detergent. Place the filter
end of detergent suction tube into
the detergent container.
STEP 2: Apply safety latch to spray gun trigger.
NOTE: Detergent cannot be applied using the yellow
nozzle.
STEP 3: With the motor
running, pull trigger to operate
machine. Liquid detergent is
drawn into the machine and
mixed with water at an approxi-
mate ratio of 15 to 1. Turn
pressure control handle on
wand counterclockwise. This
lowers the pressure by directing the water flow through
the soap nozzle and allow detergent injector to siphon
soap.
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.

Cleaning Tips
Pre-rinse cleaning surface with fresh water. Place
detergent 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 over-
lapping 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
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.
