working in accordance with the requirements
of the regulations in force (earth connection,
fuses, differential 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).
A wrong connection let the motor slew in an
irregular way, and consequently the gas oil
suction pump will not operate in a correct
way. If the gas oil pump does not suck fuel, it
will damage and it will not allow the burner
to work. To check the correct rotation of the
motor, it is necessary to check if air goes out
from the chimney.
FILLING UP WITH FUEL
Fill the tank with the fuel indicated on the tech-
nical data plate (Diesel, ref. 4).
Avoid that the tank is empty when the machine
is running in order not to damage the fuel
pump.
•
Incorrect fuel shall not used as they as
provide hazard.
Fill up the detergent tank with the suggested
products, suitable for the kind of washing to be
carried out (ref. 5).
•
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.
START-UP
Switch on the machine by pressing the switch
(ref. 1, pos.1) 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
fit 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.
To wash with hot water, press the switch (ref.
1, pos. 5) and turn the thermostat (ref. 1, pos.
2) to the desired temperature setting. To add
detergent or disinfectant to the water jet, open
the regulator (ref. 1, pos. 3) to the setting for the
quantity required as described in the "DETER-
GENT SUCTION" section.

To fit the lance to the gun, it is sufficient to in-
sert the threaded end of the lance (ref. 8, pos.
1) into the hole on the gun (ref. 8, pos. 2); then
screw the lance as shown by the arrow (A) until
the connection is tight.
>
The adjusting head allow you to select water jet
at low and high pressure. The pressure selection
is carried out by rotating the adjusting head. To
increase the pressure, rotate the adjusting head
clockwise (fig. 9, Pos. A), to reduce the pressure
rotate it anti-clockwise (fig. 9, pos. B). The de-
tergent suction is automatic when the adjust-
ing head of the lance is rotate for low pressure
operation (anti-clockwise).
When you start the machine, the mixing of the
detergent with the water is automatic at the
water passage. The quantity of sucked deter-
gent depends on the quantity set with the de-
tergent adjusting knob (ref. 1, pos. 3).

Whenever the machine has to be stopped, it is
important to engage the safety catch (S, ref. 10)
on the gun so that it cannot be operated acci-
