High Pressure Cleaner
9
Adjustable spray nozzle
The adjustable nozzle will allow you to use
any variety of spray patterns from a full fan
spray (Diagram 2) to a direct stream spray
(Diagram 1). When using the pressure wash-
er to clean wood decks, siding, vehicles etc.,
always start using the fan spray and begin
spraying from a minimum 36” away to avoid
damaging the surface of the material you are
cleaning. Always begin by spraying in a test-
ing area free and clear of people and objects.
– WARNING: High pressure jets can be
dangerous if subject to misuse. The jet
must not be directed at persons, live
electrical equipment or the appliance
itself.
– Do not direct the jet against yourself or
others in order to clean clothes or foot-
wear.
Unblock lance
When the nozzle is clogged, it will cause the
pump to build pressure and may cause unit
to surge, you can clean the nozzle inserting
needle into the tip to rid of the deposits.
For the adjustable nozzle, you can lubricate
the nozzle collar(high pressure to low pres-
sure )by using non-water soluble grease reg-
ularly .
Using detergents
– The pressure cleaner will dispense deter-
gent at low pressure.
– Use the adjustable spray nozzle to rinse
clean.
– Biodegradable detergents are specifically
formulated to protect the environment and
your pressure cleaner.
–
These detergents will not clog the fi lter and
will protect the internal parts of the pres-
sure cleaner for a longer life.
The built-in detergent dispenser will allow you
to apply many forms of liquid detergent onto
the work surface.
Detergent application happens at low-pres-
sure only.
Insert the adjustable nozzle onto the gun, and
turn it to end of “LOW” , so that the pressure
washer is in low-pressure mode (
see Figure
A below).
Remove the cap on the detergent reservoir
and fi ll with liquid detergent only ( see Figure
B below).
Do not put any water into the reservoir.
The pressure washer will mix water and de-
tergent automatically. When fi nished applying
the detergent to the work surface, turn it to
end of “HIGH” of the adjustable nozzle and
spray off the detergent by using the high-pres-
sure spray (see Figure A below).
In high-pressure mode, the pressure washer
will not dispense detergent.
WARNING: never use products with bleach
or chlorine or any other corrosive materials,
including liquids containing solvents (i.E. Gas,
oils etc), tri-sodium phosphate products, am-
monia, or acid-based cleaners.These chem-
icals will harm the unit and cause damage to
the surface being cleaned.
