rotary nozzle onto the lance.
5.6.4 Turn the high pressure cleaner back on.
5.7 RECOMMENDED CLEANING PROCE-
DURE
5.7.1 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 sur-
face, working from the bottom upwards.
Avoid allowing the rinsing water to run on
to unwashed surfaces.
5.8 STORAGE
5.8.1 Switch off the cleaner.
5.8.2 Turn off the water supply tap.
5.8.3 After use, the detergent residues should
be removed from the tank. FIG.6E
5.8.4 Discharge residual pressure by pressing
the trigger until no more water comes out
of the adjustable nozzle.
5.8.5 Engage the gun safety catch.
5.8.6 Remove the plug from the socket.
5.8.7 Operate the cleaner with non-
corrosive/non-toxic antifreeze before sto-
ring for the winter.
5.9 USE AND CHARACTERISTICS OF TRO-
NIC MODELS FIG.5G
5.9.1 Functional features (single-phase models
only)
1 - Motor on-off by operating the gun trig-
ger.
2 - Continuous pressure regulation from
min. 20 bar to 150 bar. (FOR MODELS
WITH THIS FEATURE).
3 - Motor power supply cut-out in case of
power failure. Prevents inopportune motor
restart (IEC 335-2 regulation).
4 - Time delay device on motor ~ 8 seconds
after release of the gun trigger. Prevents
surge currents caused by motor startup
both in the domestic electrical supply
(DIFFERENTIAL SAFETY BREAKER)
and in the control circuits of the appliance
(RELAYS and electronic circuit).
5 - Safeguarding the sealing system of the
appliance.
Do not use the appliance for prolonged
periods at zero pressure (bypass recy-
cling) or allow the water to overheat since
these could damage the sealing system.
6 - User-friendly, long-life ON-OFF switches.
The controls on the control panel of the
appliance are of the TOUCH-PAD PUSH-
BUTTON type, thus ensuring easy opera-
tion and optimum protection against water
frequency (Volts/Hz) correspond to those
specified on the cleaner data plate. FIG.4E
If the power supply is correct, you may
now plug in the cleaner.
The cleaner must only be connected to
power sockets with regulation earth con-
nection. A differential safety breaker (30
mA) will increase the safety of operators.
CAUTION! The machine may
cause electrical disturbances
when starting.
4.6.1 If the motor stops and fails to restart, wait
2 to 3 minutes before restarting.

5 USE
5.1 Turn on the water supply tap fully.
5.2 Release the safety catch FIG.5A, then
press the trigger for a few seconds to
allow air to escape and to discharge
residual pressure in the pipes.
5.3 Keeping the trigger pressed, push the
switch to start the motor. FIG.5B
Turn the pressure control knob to the de-
sired setting. FIG.5C (FOR MODELS
WITH THIS FEATURE).
5.3.1 When re-starting the motor, always
keep the trigger pressed.
5.4 USING DETERGENT
5.4.1 CAUTION: liquid detergent must
be sprayed at low pressure. See
5.5 “Proper use of standard accesso-
ries”.
5.4.2 Fill the detergent tank to the level indicated
through the inlet. FIG. 5D
5.4.3 Select LOW PRESSURE (see instruc-
tions); the detergent will be sucked up and
mixed with the water, with the suction rate
regulated by the knob provided. FIG. 5F
5.4.4 Now distribute the detergent drawn in and
mixed with water.
5.5 Correct use of standard accessories
FIG.5E
5.5.1 The cleaner is equipped with the adjusta-
ble nozzle, which provides some impor-
tant functions:
5.5.2 LOW PRESSURE operation (for suction
and spraying of detergent).
5.5.3 HIGH PRESSURE operation (for high
pressure washing and rinsing).
5.5.4 Jet adjustment from pencil to fan. (For
models with this feature) FIG.5E
5.6 CORRECT USE OF THE ROTARY
NOZZLE (Where fitted)
5.6.1 For increased washing power, use the
rotary nozzle kit as follows:
5.6.2 Turn off the high pressure cleaner
5.6.3 Unscrew the adjustable head and fit the
