battery connector (1).
2. Connect instead the machine connector (2).
BATTERIES CHARGE LEVEL INDICATOR
To start any function of the machine, it is necessary to rotate
clockwise the key switch (A). Rotating it counterclockwise any
function will be switched off.
WHEN THE MACHINE IS SWITCHED ON, ON THE DISPLAY (1) APPEAR
IN SEQUENCE THE FOLLOWING INFORMATION:
1. the machine model (for example AdL).
2. the setting of the battery check card which can be:
GE 24 (check card set for GEL batteries).
or
Pb 24 (check card set for lead batteries).

10
3. the version of the software programme of the card (for example
5-9).
4. The batteries charge level indicator is digital and remains fixed
on the display. The battery charge level starts from -100-, which
indicates the 100% of the total charge and decreases from 10 to
10. When the charge level reaches -20-, the display starts
blinking, so you are about the end of working.
When the indication -10- appears blinking, automatically the brushes
stop, while the suction continues to work. When visualizing the four
lines blinking, also the suction will stop automatically. Instead, the
traction system remains functioning to enable the transfer of the
machine to the place provided for the tank emptying and for the
recharge of the batteries.
SETTING OF THE BATTERY CHECK CARD
The setting of the battery check card can be:
GE 24 (check card set for GEL batteries).
or
Pb 24 (check card set for lead batteries).
The machine, if not specified otherwise, is supplied with the battery
check card set for lead batteries. To modify this setting, it is necessary
to:
1. Switch off and on the machine.
2. Immediately after having switched on, when on the display (1)
the writing Pb24 appears, press simultaneously the push buttons
(2) and (3) up to the blinking of the writing.
3. When the writing begins to blink, take off the fingers from the
push buttons and press once the push button (3).
4. The writing GE24 appears blinking.
5. When the writing stops to blink, the setting is modified.
6. For the passage of the setting from gel batteries into lead
batteries, repeat the procedure pressing button (2) instead of
button (3).
As the machine is a 24V model, do not set the batteries at 36V.

11
HOUR METER
The machine is equipped with an hour meter located on the same
display (1) of the battery charge level indicator. Keeping the button
(2) pressed, the first data indicates the working hours and after a few
seconds the working minutes are shown.
SQUEEGEE ASSEMBLY
1. Maintain the squeegee support (1) slightly lifted from the floor.
2. Insert the threaded parts of the two knobs (2) making them slide
inside the two slots present on the support.
3. Put the washers (3) into position, they are two for each knob, so
that they are assembled one under and the other on each of the
two slots present on the support.
4. Block the squeegee by rotating the two knobs (2) clockwise.
5. Insert the squeegee hose (4) into its coupling, respecting its
position as indicated in the figure.
ADJUSTMENT OF THE SQUEEGEE
In order to have a perfect drying result through the squeegee, the
rear rubber must have the lower bending uniformly adjusted in all its
length. For the adjustment, it is necessary to put oneself in working
condition and therefore the suction motor has to be switched on and
the brushes have to function together with the detergent solution.
The lower part of the rubber is too much bent
Take off the pressure rotating the wing nut (6) counterclockwise.
The lower part of the rubber is not much bent
Increase the pressure rotating the wing nut (6) clockwise. Check that
the wheels which adjust the height do not rest on the floor, in this
case adjust them as indicated in paragraph "Height adjustment".
The bending is not uniform
Adjust the squeegee inclination rotating counterclockwise the wing
nut (7) to increase the bending in the central part, or clockwise to
increase the bending on the extremities.
Height adjustment
Once that the pressure and inclination of the squeegee have been
adjusted, it is necessary to fix this optimum condition making touch
slightly the wheels onto the floor. Rotate the registers (8): clockwise
to lower the wheels or counterclockwise to raise them. Both wheels
must be adjusted in the same measure.
Every type of floor requires a specific adjustment. For example,
concrete floors (where the friction results to be high) need little
pressure, while smooth floors (ceramics) need higher pressure.
If the cleaning operations are made always on the same type of floor,
the adjustment can change only in function of the rubber wear.
SPLASH GUARD ASSEMBLY
The two splash guards have to be assembled onto the brushes base
group as indicated in the following figures. Insert the metal strips
inside the suitable slots present on the rubber. Place the round hole
at the extremity of the strip onto the pin (1) placed in the front part
of the brushes base group. Secure the strips through the nut blocking
it.
Block the coupling lever (2) in the rear part of the brushes base group
to the ring placed at the extremity of the metal strip still free. Please
act as above for both splash guard rubbers.
With the brushes assembled, the splash guard must slightly touch the
floor.
For the disassembly it is necessary to proceed inversely with above-
mentioned operations.

12
BRUSHES ASSEMBLY
To assemble the brushes it is necessary that the brushes base is in the
lifted position. If it is not lifted, proceed as follows:
Without the operator seated, turning the key switch clockwise, the
display comes on and after 3 seconds all working groups come off
automatically and are lifted from the floor.
Switch off the machine turning the key counterclockwise.
With the brushes base group in lifted position, insert the brushes into
their plate seat underneath the brushes base turning them until the
three metal buttons are properly seated in their slots; rotate
energically the brushes to push the button towards the coupling
spring until they get blocked.
The figure shows the rotating sense for brushes coupling.
For a longer life of the brushes we suggest to invert daily their
position. Whenever brushes result to be deformed we suggest to
reassemble them in the same position, in order to avoid that the
different inclination of the bristles causes excessive motor overload
or troublesome vibrations.
Use only brushes supplied with the machine or the ones indicated in
the manual “RECOMMENDED BRUSHES”. The use of other brushes can
compromise the good washing result.
FLOOR CLEANING
RECOVERY TANK
Check that the cover of the suction filter (1) is correctly secured, after
rotating the levers (2) and that the suction motor hose (3) is correctly
connected to it.
Verify also that the squeegee hose couplings (4/5) are correctly
inserted into their seats and that the exhaust hose plug (6) placed in
the rear part of the machine is well closed.
DETERGENT SOLUTION TANK
The capacity of the detergent solution tank is indicated in the
technical data.
Open the screw plug placed in the left part of the machine and fill
the detergent solution tank with clean water at a maximum
temperature of 50°C. Add the liquid detergent in the percentage and
conditions foreseen by the manufacturer. To avoid excessive foam
presence, which could cause problems to the suction motor, use the
minimum percentage of detergent. Screw down the plug to close the
tank.
Use always low foam detergent. To avoid foam presence, before
starting working operation, introduce into the recovery tank a
minimum quantity of anti-foam product.
Never use pure acid.
3SD SYSTEM SOLUTION SAVING SYSTEM DISPENSER (OPTIONAL)
The system permits the predetermined dosing of the detergent
percentage which will be mixed with the water of the solution tank.
The detergent is contained in a transparent tank with a capacity of 8
litres, placed in the front part of the machine.

13
With the brushes moving, pressing once the push button (A) on the
instrument board, on the display (1) the indication shows the
detergent percentage which is being used.
Pressing the same push button in succession, six different possibilities
of settings can be selected and the display (1) visualizes always the
percentage.
The indication of the level corresponds to the following detergent
percentages in the water:
d 0.0
d 0.3
d 0.6
d 1.2
d 2.4
d 4.5
The dosing adjustment set remains stored by the system also with the
machine stopped.
The water flow is adjusted through the 8-way commutator (B): one
OFF position and 7 operating positions from a minimum of 1,2
litres/min to a maximum of 3,7 litres/min.
In OFF position both the water flow and its relative detergent flow is
interrupted.
When the commutator (B) is in OFF position, an auxiliary water
system can be activated, that permits the traditional use of the
machine and therefore the filling of the solution tank with water and
detergent. In this case it is necessary to open and adjust manually a
solution valve (C) placed under the machine. In this situation the
push button (A) handles the command of the solenoid valve in
manual function.
NOTE: when restarting with the work in mode 3SD, it is important
that the solution valve (C) is closed, this to maintain the
predetermined proportions water-detergent.
NOTE: if the automatic dosing system is not being used for a long
time, it is possible that the hoses of the detergent circuit are emptied
and therefore at the first use, the detergent begins to come out onto
the brushes with a certain delay compared to the water outlet.
Through the solution valve (D) it is possible to empty the detergent
tank and to recover the detergent.
STARTING OF THE MACHINE
A safety device avoids the machine’s movement if the operator is not
seated correctly on the guiding place.
To switch on the machine:
1. Sit on the guiding place.
2. Adjust the seat position through the release lever placed on the

3. Turn the key switch (1) clockwise to switch on the machine.
Automatically, the machine gets ready in manual (MAN) mode
and in forward movement with the quick speed (signal lamp 2).
4. Check the charge level of the batteries on the display (3).
5. Pressing the push button (7) the functioning of BREAK
WASHING is chosen and the transfer operations of the machine
are carried out (see under paragraph “FORWARD AND
BACKWARD MOVEMENT"). When the signal lamp (6) is on, then
the machine is in BREAK WASHING mode.
6. Pressing the push button (8) the automatic (AUTO) functioning
is chosen, while pressing the push button (5), the functioning of
the machine becomes manual (MAN).
A. When the signal lamp (9) is on, the machine is functioning
in automatic (AUTO) model and the machine activates and
deactivates all the working functions in an automatic mode
(see under paragraph “WORKING IN AUTOMATIC MODE”).
B. When the signal lamp (4) is on, the machine is functioning
in manual (MAN) mode and it is possible to choose if:
I. to carry out the only transfer of the machine
without activating or deactivating the working
functions.
II. to activate separately only the controls relative to
the washing function with the brushes (see under
paragraph “WORKING IN MANUAL MODE”).
III. to activate separately only the controls relative to
the drying function with the squeegee (see under
paragraph “WORKING IN MANUAL MODE”).

14
In manual mode every function of the machine has to be activated
or deactivated manually.
FORWARD AND BACKWARD MOVEMENT
It is recommended to carry out always the mere transfer of the
machine in mode (BREAK WASHING).
To proceed to activate the movement of the machine:
1. Sit on the guiding place.
2. Turn the key switch (1) clockwise to switch on the machine.
3. Check the charge level of the batteries on the display (5).
4. Pressing the push button (7) the functioning of BREAK
WASHING is chosen to carry out the mere transfer of the
machine. In fact, in this mode the washing functions of the
machine are not working and only the traction system functions.
When the signal lamp (6) is on, then the machine is in BREAK
WASHING mode.
5. Check through the signal lamp (9) that the parking brake is not
inserted and eventually release it (see under paragraph
EMERGENCY-PARKING BRAKE”).
6. Positioning the selector (8) forward, the forward drive is chosen,
while positioning it back, the rear drive is chosen.
7. Press the accelerator pedal placed on the right part of the
platform to start the machine.
8. Adjust the movement speed in forward pressing every time the
push button (2) to choose the slow one (at the maximum 3,6
km/h is reached) or the fast one (at the maximum 5 km/h is
reached). The signal lamp (3) indicates that the fast drive is
selected, while signal lamp (4) indicates that the slow drive is
selected.
9. In backward movement, when the machine is moving, an
intermittent warning device is activated, selecting the backwards
movement the squeegee is brought automatically to the upper
position. It will then lower again in the following forward
movement.
This happens both in automatic as in manual mode in order to
protect the integrity of the squeegee.
HORN
The machine is equipped with a horn which is activated pressing the
push button (1).
WORKING BRAKE
To stop the machine during normal working situations, it is sufficient
to release the accelerator pedal, because the machine has got an
electronic brake system. To restart, press again the accelerator pedal.
EMERGENCY-PARKING BRAKE
In case of an emergency press the pedal of the emergency and
parking brake (1) placed on the left side.
To insert the parking brake press the brake pedal (1) and

optimum flow, depending on the type of floor and the type of
dirt (see under the paragraph “FLOW ADJUSTMENT OF THE
DETERGENT SOLUTION”).
4. Position the selector (2) forward to choose the forward drive.
5. Adjust the movement speed in forward with the push button (1)
(see under paragraph "FORWARD AND BACKWARD
MOVEMENT").
6. Pressing the accelerator pedal, the machine begins to proceed
and in automatic mode all the working functions are activated.
In fact, automatically both the brushes base and the squeegee
go down, the brushes begin to turn, the solenoid valve opens to
permit the detergent solution to flow down onto the brushes
and the suction system is activated to recover the dirty water
from the floor.
Positioning backwards the selector (1) to choose the rear drive and
pressing the accelerator pedal the rear drive starts, the squeegee lifts
automatically and will then return to lower itself during the next
forward movement.
If the accelerator pedal is released for more than 3 seconds,
automatically all the functions are being switched off and both
the brushes base and the squeegee are being lifted.
Pressing again the pedal, the machine starts to move again and
in automatic mode all the working functions are reactivated.

15
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.
1. Activate the machine (see under paragraph “STARTING OF THE
MACHINE”).
2. Pressing the push button (2) the functioning of manual (MAN)
mode is chosen. When the signal lamp (1) 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 (8) is in the position of
optimum flow, depending on the type of floor and the type of
dirt (see under the paragraph “FLOW ADJUSTMENT OF THE
DETERGENT SOLUTION”).
2. Press the push button (6) of up/down of the brushes base to
lower the brushes. Once that it is lowered, the brushes begin to
turn. The blinking signal lamp (7) indicates that the brushes base
is lowering or lifting (it remains on when the brushes base is in
working position), while the signal lamp (5) signals that the
brushes are turning.
3. Press the switch (4) to open the solenoid valve and permit the
detergent solution to lower onto the brushes. The signal lamp (3)
will come on, to indicate that the solenoid valve is open.
TO CARRY OUT THE FUNCTION OF ONLY DRYING:
1. Press the push button (14) of up/down squeegee to lower the
squeegee. The blinking signal lamp (13) indicates that the
squeegee is lowering or lifting (it remains on when the squeegee
is in working position).
2. Press the switch (12) of the suction motor to start the suction
system. The signal lamp (11) indicates that the machine is drying.
3. Position the selector (9) forward to choose the forward drive.
4. Adjust the movement speed in forward with the push button
(10) (see under paragraph "FORWARD AND BACKWARD
MOVEMENT”).
5. Pressing the accelerator pedal, the machine begins to proceed
forward and to work according to the set functions.
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 perfect drying result
(see under paragraph “ADJUSTMENT 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 DETERGENT 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 BRUSHES PRESSURE”).
FLOW ADJUSTMENT OF THE DETERGENT SOLUTION
To adjust the detergent solution quantity that flows down onto the
brushes it is necessary to act upon the solution valve knob (1) 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
Through the knob (4 it is possible to adjust the brushes pressure onto
the floor in three pre-set pressure levels. We can visualize on the
display (1) the pressure in kg previously set by pressing the push
button (3).
The adjustment occurs in this way both in automatic and in manual
mode.
In order not to overload the brushes motor, it is convenient to reduce
the brushes pressure going from smooth floors to rough ones (ex.
concrete). The visualization of the blinking led (2) indicates an
overload of the brushes motor. It is therefore necessary to reduce the
pressure up to the level where the blinking warning stops.

16
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.
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 motor, the machine
is equipped with a mechanical float that intervenes when the
recovery tank is full, closing the air flow of the suction.
When this happens, it is necessary to empty the recovery tank (see
under paragraph “RECOVERY TANK EMPTYING AND CLEANING”).
AFTER CLEANING OPERATION
IN AUTOMATIC OR MANUAL WORKING MODE:
1. A the end of the washing cycle, pressing the push button (1), the
functioning of BREAK WASHING is chosen. When the signal
lamp (2) is on, then the machine is in BREAK WASHING mode. In
this way automatically the brushes lift, the solenoid valve shuts
down and it is possible to finish the drying operation for a total
time of about 15 seconds, afterwards also the squeegee is lifted
and the suction stops.
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 15 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.
Starting again the cleaning operation:
A. by pressing the push button (4) 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 re-established manually.
