Operations
Detergent and General Operating Techniques
WARNING: Some detergents may 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 manufacturer. 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. Secure
black detergent nozzle into quick coupler.
NOTE: Detergent cannot be applied using the Yellow
nozzle.
STEP 3: With 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 the engine on your pressure washer for 2-3
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach high tempera-
tures. 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
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
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.

Storage
Pump Storage
CAUTION: Always store your
pressure washer in a location where
the temperature will not fall below
32° F (0° C). The pump in this
machine is susceptible to
permanent damage if frozen.
ATTENTION:Toujours entreposer la laveuse à
pression dans un endroit où la température ne sera
pas inférieure à 32° F (0° C). La pompe sur cette
machine est susceptible de subir des dommages si
elle est exposée au gel.
FREEZE DAMAGE IS NOT
COVERED BY WARRANTY.
If you must store your pressure washer in a location
where the temperature is below 32° F, you can
minimize the chance of damage to your machine by
draining your machine as follows:
1. Stop the pressure washer and detach supply hose
and high pressure hose. Squeeze the trigger of the
spray gun to drain all water from the wand and
hose.
2. Restart pressure washer and let it run briefly (about
5 seconds) until water no longer discharges from
the high pressure outlet.
