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.
AVERTISSEMENT: Certains
détergents peuvent être dangereux
s'ils sont inhalés ou ingérés,
provoquant de fortes nausées, des
évanouissements et l'empoisonnement. Les
éléments dangereux peuvent causer des dommages
à la propriété ou des blessures graves
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. Open variable pressure
wand handle to low pressure which
allows water through black
detergent nozzle.
NOTE: Detergent cannot be applied
during high pressure.
STEP 3: 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 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 your pressure washer for 3-5 minutes without
pressing the trigger on the spray gun, circulating water
in the pump can reach high temperatures. When the
water reaches this temperature, 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
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.
