Detergents & General Cleaning 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 déter-
gents peuvent être dangereux s'ils
sont inhalés ou ingérés, provo-
quant de fortes nausées, des
évanouissements et l'empoisonne-
ment. 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 at end of
insulated straight wand. See page 12 for variable pressure
wand instructions.
NOTE: Detergent cannot be applied using the high
pressure nozzle.
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 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
•
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
Ces produits chimiques endommageront la machine et
endommageront la surface étant nettoyée.
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.
