STEP 1: Use detergent designed
specifically for pressure washers.
Household detergents could
damage the pump. 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 2:Turn variable pressure control valve on the
wand counter clockwise for low pressure until you
observe detergent flowing through the detergent pick-
up tube

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 with detergent valve open 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 or acid-based products
ATTENTION: Ne jamais utiliser:
• Eau de Javel, produits à base de chlore et
autres produits chimiques corrosifs
