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 Landa 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 pick- up tube
into the detergent container.
STEP 2:
Turn detergent valve
counterclockwise until desired
amount of detergent flow is
achieved.
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 after
each use by placing the suction tube into a bucket
of clean water. Then run the pressure washer for 1-
2 minutes. Turn detergent valve clockwise after
flushing with clean water to prevent air from
entering pump.
Thermal Pump Protection
If you run your pressure washer for 3 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
•
Acid-based products
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.
