● Screw the outlet pressure hose onto the machine
and ensure a good hand tight fi t.
● Connect the spray lance to the trigger by means of
the push in and twist bayonet fi tting.
GB
Ensure that this connection has been performed
positively and the bayonet has located correctly. En-
sure the hose has no kinks in it.
4. USE
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 fi rst) to
let water pass through the unit and expel any air.
WARNING! This unit is to be used with a
coldwater source only!
ELECTRICAL CABLES
Ensure that all cables are damage free before connect-
ing to the power supply.
The electric supply connection shall be made by
a qualifi ed 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 electri-
cal disturbances when starting. If the motor
stops and fails to restart, wait 10-30 minutes
before
TRIPPED
CAUTION! The cleaner must only be used
with clean water; use of unfi ltered water or
corrosive chemicals will damage the cleaner.
● Turn the motor switch to the "0" position.
● Check that the electrical supply voltage and fre-
quency (Volts/Hz) correspond to those specifi ed on
the cleaner data plate.
● Plug in the pressure washer and turn the unit on with
the main switch .
ADJUSTING THE NOZZLE
Water may be sprayed out of the nozzle either linearly
or in a fan shape. Turn on the pressure fi rst, and then
adjust the nozzle.
The water inlet fi lter must be inspected regularly, so as
to avoid blockage and restriction of the water supply
to the pump.

USING THE DETERGENT BOTTLE
To enable supply of detergent from the bottle, remove
nozzle of the spray lance according to the arrow on the
Fig. 3a.
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 run-
ning, detergent will spray out with the water.
RECOMMENDED CLEANING PROCEDURE
Dissolve dirt by applying detergent with the fan jet to
the dry surface. On vertical surfaces, work from the
bottom upwards. Leave the detergent to act for 1 to
2 minutes, but do not allow to dry out. Apply the high
pressure jet, keeping the nozzle at least 30 cm (10 in.)
from the surface, working from the bottom upwards.
Avoid allowing the rinsing water to run on to unwashed
surfaces.
SHUTTING DOWN THE PRESSURE
WASHER
CAUTION! Never disconnect the high-pres-
sure hose from the machine while the system
is still pressurized.
Follow the correct procedure:
1. Turn off the pressure washer by using the switch on
the machine.
2. Unplug the unit from the power source.
3. Turn off the water supply at the tap.
4. Press the trigger of the gun to depressurize the sys-
tem.
5. Disconnect the supply hose to the machine
6. Wipe all surfaces of the unit with a damp clean
CUTOUT cloth.
7. Engage the safety lock.
THE SUCTION FUNCTION
You can connect the high pressure cleaner to the water
sources such as taps or pump water from other sources
without pressure.
To work with the water supply without pressure the
suction hose should be removed from the supply and
the gun nozzle should be moved to position "Low"
(Figure 14). After that the high pressure cleaner should
work idle for a few seconds to drain the excess water
and release air. Put the suction hose into the water
source. After draining some water the gun nozzle
should be moved to position "High" (Figure 14). Now
the high pressure cleaner is ready to work under high
pressure.
