on with the main switch (3).
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. 3
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.
The water inlet filter must be inspected regu-
larly, so as to avoid blockage and restriction of
the water supply to the pump. (fig 4)
using the detergent bottle
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.
On vertical surfaces, work from the bottom
Ferm
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-
pressure 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
system.
5. Disconnect the supply hose to the machine
6. Wipe all surfaces of the unit with a damp clean
cloth.
7. Engage the safety lock.
5. service & maintenance
Warning! Unplug the electric cable
(power source) prior to any maintenance
or preparatory storage operations.
Make sure that the machine is not live when
carrying out maintenance work on the motor.
To ensure good performance, check and clean
the suction and detergent filters after every 50
hours of operation.
Long periods of disuse may lead to the
formation of lime scale deposits. Working
through the hole on the rear, RELEASE the
motor using a screwdriver (for models with this
feature).
Then remove the screwdriver and proceed with
the restart operations.
Malfunction
Should the machine fail to function correctly, a
number of possible causes and the appropriate
solutions are given below:
1. When switched on, the machine will not
start working.
Plug is not well connected or electric socket is
faulty.
Check plug, socket and fuse.
The mains voltage is lower than the minimum
