WORKING IN MANUAL MODE

The manual mode is useful when, in special cases, it
is necessary to carry out separately only the washing
with the brushes or only the drying of the floor.
ATTENTION:
The washing and drying functions, when they are
not carried out simultaneously, represent an im-
proper use of the machine (see under paragraph
"GENERAL RULES OF SECURITY"). If they are car-
ried out separately, it is necessary to forbid the
working areas to the passage of non-authorized
personnel and to signal the areas of moist floors
with suitable signs.
1. Activate the machine (see under paragraph
"STARTING OF THE MACHINE").
2. Pressing the push button (3) the functioning of
manual (MAN) mode is chosen. When the signal
lamp (2) is on, then the machine is functioning in
manual (MAN) mode.
TO CARRY OUT THE WASHING WITH ONLY THE
BRUSHES:
1. Check that the knob of the solution valve (27) is
in the position of optimum flow, depending on the
type of floor and the type of dirt (see under the par-
agraph "FLOW ADJUSTMENT OF THE DETERGENT SO-
LUTION").
2. Press the push button (17) of up/down of the
brushes base to lower the brushes. Once that it is
lowered, the brushes begin to turn. The blinking sig-
nal lamp (16) indicates that the brushes base is low-
ering or lifting (it remains on when the brushes base
is in working position), while the signal lamp (18)
signals that the brushes are turning.
3. Press the switch (19) to open the solenoid valve
and permit the detergent solution to lower onto the
brushes. The signal lamp (20) will come on, to indi-
cate that the solenoid valve is open.
TO CARRY OUT THE FUNCTION OF ONLY DRYING:
1. Press the push button (11) of up/down squeegee
to lower the squeegee. The blinking signal lamp (12)
indicates that the squeegee is lowering or lifting (it
remains on when the squeegee is in working posi-
tion).
2. Press the switch (9) of the suction motor to start
the suction system. The signal lamp (8) indicates that
the machine is drying.
Position the selector (28) forward to choose the for-
ward drive.
Adjust the movement speed in forward with the
push button (21) (see under paragraph "FORWARD
AND BACKWARD MOVEMENT").
Pressing the accelerator pedal, the machine begins
to proceed forward and to work according to the set
functions.
ATTENTION:
In manual mode every function of the machine
has to be activated or deactivated manually.

WORKING ADJUSTMENTS

Both in automatic as in manual mode, during the
first metres check:
1. that the squeegee adjustment guarantees a per-
fect drying result (see under paragraph "ADJUST-
MENT OF THE SQUEEGEE").
2. that the adjustment of the detergent solution
flow is sufficient to wet the floor uniformly avoiding
the leakage of detergent from the splash guards (see
under paragraph "FLOW ADJUSTMENT OF THE DE-
TERGENT SOLUTION").
3. that the brushes pressure permits an efficient
washing action in function of the dirt and the speed
(see under paragraph "ADJUSTMENT OF THE BRUSH-
ES PRESSURE").
FLOW ADJUSTMENT OF THE DETERGENT SOLU-
TION
To adjust the detergent solution quantity that flows
down onto the brushes it is necessary to act upon
the solution valve knob (27) placed on the right of
the steering column, rotating counterclockwise to
increase it and clockwise to reduce it up to close the
flow.
It is better to adjust the water flow during work and
at every adjustment of the brushes pressure.

ADJUSTMENT OF THE BRUSHES PRESSURE

Both in automatic as in manual mode it is possible
through the knob (10) to adjust the brushes pressure
on the floor in eight established levels. During the
operation, we can visualize on the display (1) the
value in percentage of the electric absorption of the
brushes motor by pressing the button (14).
The adjustment in this mode is done both in auto-
matic and manual operation.

ATTENTION:
In order not to overload the brushes motor, it is con-
venient to reduce the brushes pressure going from
smooth floors to rough ones (ex. concrete).
The presence on the display (1) of a blinking warning
from P2 to P8 indicates that the pressure level set
determines an overload of the brushes motor. It is
therefore necessary to reduce the pressure up to the
level where the blinking warning stops.

ELECTRIC PROTECTION

The machine is equipped with an electronic system
of protection 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 damages to the suction mo-
tor, the machine is equipped with a mechanical float
that intervenes when the recovery tank is full, clos-
ing the air flow of the suction.
When this happens, it is necessary to empty the re-
covery 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 ma-
chine 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
