harmful if inhaled or ingested,
causing severe nausea, fainting or
poisoning. The harmful elements
may cause property damage or
severe injury.
AVERTISSEMENT: Certains déter-
gents peuvent être dangereux s'ils
sont inhalés ou ingérés, provo-
quant 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 manufacturer. Fill a
container with pressure washer deter-
gent. Place the filter end of detergent
suction tube into the detergent
container.
STEP 2: Apply safety latch to spray gun trigger. Secure
black detergent nozzle into quick coupler.
NOTE: Detergent cannot be applied using the Yellow
nozzle.
STEP 3: Selection of high or low pressure is accompanied
by turning the handle. NOTE: High pressure nozzle must
be inserted at end of wand to obtain high pressure. To
apply soap connect detergent injector to discharge nipple
and secure by pushing coupler collar forward. Turn handle
to lower pressure (water will exit both nozzles). Place
detergent pick-up tube into detergent container. Rinse by
turning handle for high pressure.

STEP 4: With the engine
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 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 products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinner,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products or acid-based products
These chemicals will harm the machine and will damage
the surface being cleaned.
ATTENTION: Ne jamais utiliser :
• Eau de Javel, produits à base de chlore et autres
produits chimiques corrosifs
• Liquides contenant des solvants (c.-à-d. diluant à
peinture, essence, huiles, etc.)
• Produits à base de tripolyphosphate de sodium
• Ammoniac ou produits à base d'acide
