2. Unplug the unit from the power source.
3. Turn off the water supply.
4. Press the trigger of the gun to depressurize the
system.

washer.
6. Wipe all surfaces of the unit with a damp clean

CAUTION: ALWAYS turn off the unit's motor
BEFORE turning off the unit's water supply.
Serious damage could occur to the motor if the
unit is run without water.
CAUTION: NEVER disconnect the high-pressure
discharge hose from the machine while the
system is still pressurized. To depressurize the
unit, turn off the motor, turn off the water supply
and squeeze the trigger 2-3 times
Water supply
• Ensure that you have a suitable water supply
to feed the pressure washer. Check that all
connections are tight and there are no leaks in
the hose.
• The supply tap should be fully open (do not
turn on the pressure washer yet).
• Now depress the trigger (unlock trigger lock
first) to let water pass through the unit and
expel any air.
Warning! This unit is to be used with a
cold-water source only!
• Turn on the pressure washer, once all the air
has been expelled and water has reached the
end of the lance.
Electrical Cables
• Ensure that all cables are damage free before
connecting to the power supply.
Plug in the pressure washer and turn the unit
on with the main switch (2).

4. USE
CAUTION! The cleaner must only be
used with clean water; use of unfiltered
water or corrosive chemicals will damage
the cleaner.
• Turn the motor switch to the "0" position.
• Check that the electrical supply voltage and
frequency (Volts/Hz) correspond to those
specified on the cleaner data plate.
• If the power supply is correct, you may now
plug in the cleaner.
• The electric supply connection shall be made
by a qualified electrician. It is recommended
that the electric supply to this appliance
should include either a residual current device
that will interrupt the supply if the leakage
current to earth exceeds 30 mA for 30 ms or a
device which will prove the earth circuit.
CAUTION! The machine may cause
electrical disturbances when starting.
• If the motor stops and fails to restart, wait 2-3
minutes before restarting. THERMAL CUTOUT

Adjusting the nozzle
Fig. 2
• Water may be sprayed out of the nozzle either
linearly or in a fan shape. Turn on the pressure
first, and then adjust the nozzle.
Water inlet filter
Fig. 3
• The water inlet filter must be inspected regu-
larly, so as to avoid blockage and restriction of
the water supply to the pump. (fig 3)
Using the detergent bottle
Fig. 4
• The detergent nozzle and tank attaches to
the end of the trigger assembly in the same
way as the lance does. Fill the detergent tank
with liquid detergent. When the trigger is now
pressed with the machine running, detergent
will spray out with the water.
• Recommended cleaning procedure
• Dissolve dirt by applying detergent with the fan
jet to the dry surface.
