long period out of use, connect the intake line
only for a few minutes so that any dirt is vented
from the delivery outlet.
ELECTRICAL CONNECTION
Check that the mains voltage is the same as
that of your machine, indicated on the techni-
cal data plate. Your electrical system must be
constructed by qualifi ed technicians capable of
working in accordance with the requirements
of the regulations in force (earth connection,
fuses, diff erential security breaker, etc).
In case of failure to comply with one of the
regulations stated above, the manufacturer
declines all responsibility for the staff and
provides no warranty.
IMPORTANT: Regarding three-phase motors,
pay attention to the connection of the elec-
tric cable to the plug (see electric diagram).
START-UP
Switch on the machine by pressing the switch
(ref. 1, pos.7) and leave it to run for a few min-
utes to eliminate any dirt and air bubbles from
the water circuit, then switch it off , connect the
high pressure line to the spray gun (ref. 7) and
fi t the spray rod (ref. 8). Make sure that the de-
tergent regulator is in the closed position.
When the machine is running again, check that
the jet is even; otherwise, clean the nozzle to
remove any dirt. Wait a few seconds for the op-
erating pressure to be reached, then operate
the gun for two or three short bursts.
> LANCE ASSEMBLY
To fi t the lance to the gun, it is suffi cient to in-
sert the threaded end of the lance (ref. 4A-4B,
pos. 1) into the hole on the gun (ref. 4A-4B, pos.
2); then screw the lance as shown by the arrow
(A) until the connection is tight.
> DETERGENT SUCTION (OR WAX)
Fill up the detergent tank (or wax) with the sug-
gested products, suitable for the kind of wash-
ing to be carried out (ref. 1C, pos. 7).
CAUTION: Make use only of liquid deter-
gent, do not absolutely use acid or too
much alkaline products.
We suggest you
to make use of our products, which have
been studied for the use with washer ma-
chines.
CAUTION: For proper use of the tank, do
not introduce fl ammable or chemically
harsh substances.
The adjusting head allow you to select water
jet at low and high pressure. Pressure can be
adjusted by acting on nozzle knob (ref. 6): ref.
“B” means low pressure, “A” means high pres-
sure. The selection of low or high pressure shall
be carried out with gun in closed position. The
detergent suction (or wax) is automatic when
the adjusting head of the lance is positioned for
low pressure operation. When you start the ma-
chine, the mixing of the detergent (or wax) with
the water is automatic at the water passage.
To use wax or detergent, turn the suction selec-
tor as specifi ed in ref. 7.
> APPLIANCES PROVIDED WITH THERMAL
VALVE (OPTIONAL)
This device enables the machine’s by-pass op-
eration through automatic water discharge
whenever it reaches a temperature of nearly
60°C and cooling working components.
CAUTION: appliances that are not pro-
vided with this disposal must not oper-
ate for more than 2 minutes with released
gun. Recycled water raises its temperature
remarkably causing great damages to the
pump.
> GUN SAFETY DEVICE
Whenever the machine has to be stopped, it
is important to engage the safety catch (ref.
5A-5B, pos. S) on the gun so that it cannot be
operated accidentally.
> MAINTENANCE
IMPORTANT: Before doing any work on
