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 specifi-
cally 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: Open detergent metering valve.
STEP 3: Detergent will be drawn into the pump and coil and
discharged under pressure. Never use anything that will
damage the pump and coil.
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 from your machine after
each use by placing the suction tube
into a bucket of clean water and then running the
pressure washer for 1-2 minutes.

Thermal Pump Protection

If you run the engine on your pressure washer for 3-5
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.
