ELECTRIC PROTECTION
The machine is equipped with
an electronic system of pro-
tection for all components that
carry out functions of power
or control. This device blocks
the defective component and
indicates on the display (1)
the corresponding alarm from
”A1”, “A2” and on.
ATTENTION:
To restore the functioning of
the component, turn off and on
again the machine acting upon
the key switch. If the problem
persists, please contact
the authorized technical
assistance
OVERFLOW DEVICE
In order to avoid serious
damage to the suction motor,
the machine is equipped
with a mechanical float that
intervenes when the recovery
tank is full, closing the suction.
For the machines equipped
with electric float switch
(optional), the switching off
of the suction motor and its
signal lamp (12) happens
automatically.
When this happens, it is
necessary to empty the
recovery tank (see under
paragraph “RECOVERY TANK
EMPTYING AND CLEANING”).
STOP OF THE MACHINE
AFTER CLEANING
OPERATION
IN AUTOMATIC OR MANUAL
WORKING MODE:
1.A the end of the washing
cycle, pressing the push
button (5), the functioning of
BREAK WASHING is chosen.
When the signal lamp (4)
is on, then the machine is
in the functioning mode
BREAK WASHING. In this way
automatically the solenoid
valve shuts down, the brushes
are lifted of a few millimeters
continuing to turn for about 10
seconds (drying phase of the
brushes) and the collection
box drains the excess water
to the floor; then, the washing
group lifts completely while
the squeegee continues to
remain in working position
with the suction motor on,
after 5 seconds the squeegee
lifts and when it reaches the
highest position, the suction
motor stops, with a delay of
another 5 seconds.
NOTE: all these phases
are carried out with the
machine operating, so that
the squeegee can dry the
interested cleaning area from
the “drying phase of the
brushes” and furthermore
can dry the suction hose of
its dirty water. At any time
it is possible to interrupt the
procedure BREAK WASHING
by stopping the drive.
2.During the phase of BREAK
WASHING, when the accelerator
pedal is released for more than
3 seconds, the squeegee raises
itself and the suction switches
off automatically.
3.After three seconds, the
accelerator can be pressed
again, if a machine's transfer
has to be made (you can
anyway make the transfer even
if the pedal is not lifted once
that 20 seconds have passed).
4.Turn the switch key
counterclockwise to switch off
the machine.
5.Insert the parking brake (see
under paragraph “EMERGENCY
PARKING BRAKE”).
The mode (BREAK WASHING)
is specific for the transfer
at the end of the cleaning
operation
ATTENTION:
A.by pressing the push button
(6) the automatic (AUTO)
functioning is chosen to start
working in automatic mode.
B.by pressing the push
button (3) the manual (MAN)
functioning is chosen to start
working in manual mode
and all functions have to be
reestablished manually.
