1. Bring the machine on a levelled surface.
2. Rotate the seat platform forward up to the blocking of the
support.
3. Having finished any intervention, to close the battery
compartment, after having released the support, reposition the
seat platform.
BATTERY INSTALLATION AND SETTING OF THE BATTERY TYPE
The machine is equipped either with batteries in serial connection or
elements of DIN-type assembled together and connected in series for a
total of 36 Volt, placed in its appropriate compartment under the seat
platform and must be handled using suitable lifting equipment (due to
weight, considering the type of batteries chosen, and coupling system).
The batteries must be in accordance with CEI 21-5 Norms.
The machine and its battery check card foresee the use of traditional
lead batteries.
CHECK THE SETTING OF THE CHECK CARD (see under paragraph
"BATTERIES CHARGE LEVEL INDICATOR").
In case of GEL batteries installation, it is necessary to set the check card.
Please contact the authorized technical assistance.
Strictly follow manufacturer/distributor indications for the
maintenance and recharge of the batteries. All installation and
maintenance operations must be executed by specialized staff, using
suitable protection accessories.
For batteries installation it is necessary to reach the battery
compartment as indicated under paragraph “ACCESS TO THE BATTERY
COMPARTMENT”.
1. Place the batteries in its compartment.
2. Connect the terminals, respecting the polarities, avoiding
contact with other parts that could create short circuit.
ASSEMBLING OF THE ROLLBAR
For packing reasons, the support of the blinking light is supplied
disassembled.
Proceed as follows:
Take off the four fixing screws (1) from the rollbar.
Place the rollbar into their seats (2) on the tank.
Fasten the screws passing them in the same order in their holes
foreseen on the support.
Complete the assembly connecting the connectors (3) to supply the
blinking light.
BATTERY CHARGER
Make sure that the battery recharger is suitable for the installed
batteries both for their capacities and type (lead/acid or GEL and
equivalent).
In the plastic bag containing the use and maintenance you will find the
coupling connector for the recharger. It must be assembled onto the
cables of your recharger, following the instructions given by the
manufacturer.
CHARGING THE BATTERIES
1. Plug the connector (3) of the battery recharger into the battery
connector.
2. Proceed for the recharging.

9
Never charge a GEL battery with a non suitable recharger. Strictly
follow the instructions supplied by the batteries and recharger
manufacturer.
In order not to cause permanent damages to the batteries, it is
necessary to avoid their complete discharge, providing for the
recharging within a few minutes after that the batteries discharge
signal starts blinking.
NOTE: Never leave the batteries completely discharged even if the
machine is not used. In case of traditional batteries, please check the
electrolyte level every 20 recharging cycles and eventually top them up
with distilled water. Never leave the batteries discharged for more than
two weeks.
Danger of gas exhalations and emission of corrosive liquids. Fire
danger: do not approach with free flames.
CONNECTING THE BATT. CONNECTORS AND SWITCHING ON OF
THE MACHINE
Once that the battery recharging has been completed:
1. Disconnect the connector of the battery recharger from the
battery connector (1).
2. Connect then the battery connector (1) to the machine connector
(2).
3. To start any function of the machine, it is necessary to rotate
clockwise the key switch (5). Rotating it counterclockwise any
function will be switched off.
BATTERY CHARGE LEVEL
When the machine is switched on, on the display (1) appear in order the
following information:
1. the version (for example A003) of software installed on the
machine.
2. the setting of the battery check card which can be:
3. GE 36: check card set for GEL batteries.
or
4. Pb 36: check card set for lead batteries.
5. 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.
After a few seconds of the indication 10% and after this, the blinking
of the four lines, all the functions stop automatically. With the
remaining charge it is anyhow possible to finish the drying operation
before proceeding to the recharge.
HOURMETER
The machine is equipped with an hour meter located on the same
display (1) of the battery charge level indicator. Pressing the button (2),
the first data indicates the working hours and after a few seconds the
working minutes are shown.
SQUEEGEE ASSEMBLY
1. Insert the two stud bolts (2) situated on the upper part of the
squeegee (3) inside the slots present on the support (1).
2. To block the squeegee tighten the stud bolts (2).
3. Insert the squeegee hose (4) into its coupling, respecting its
position as indicated in the figure.

10
ADJUSTING 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 (5) counterclockwise.
The lower part of the rubber is not much bent
Increase the pressure rotating the wing nut (5) 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
(6) 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 clockwise the registers (7) to
lower the wheels or counterclockwise to raise them. Both wheels must
be adjusted in the same measure. To act upon the register (7) loosen at
the same time the two milled ring nuts, adjust the height acting on the
upper one and then fix the adjustment screwing and blocking the lower
one.
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.
ASSEMBLING THE SPLASHGUARDS
The two slash guards are already preassembled on the two metal covers.
To assemble the covers, it is necessary to proceed as follows:
1. Take off the clips (1) present on the pins (2) fixed to the brushes
base.
2. Assemble the cover onto the brushes base.
3. Reposition the clips (1) to block.
For the disassembly it is necessary to proceed inversely with above-
mentioned operation
(version 100)
(Version 130)
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.
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.
FLOOR CLEANING
RECOVERY TANK
Verify that the squeegee hose couplings (1/2) are correctly inserted into
their seats and that the exhaust hose plug (4) placed in the rear part of
the machine is well closed.

11
Check that the inspection cap (3) placed on the upper part of the tank
is well closed.
Finally, verify the correct tightening of the closing lever (5) of the
cleaning door (6) placed in the lower part of the tank.
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 (122°F). 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 motors, use the minimum
percentage of detergent. Screw down the plug to close the solution
tank.
The switching on of the signal lamp of low detergent (19) indicates that
the detergent solution is nearly exhausted.
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.

12
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. Turn the key switch (5) clockwise to switch on the machine.
3. Check the charge level of the batteries on the display (1).
4. With the selector (12) in central position (BREAK WASHING) the
transfer operations of the machine are carried out (see under
paragraph “FORWARD AND BACKWARD MOVEMENT").
5. Moving the selector (12) onto the left, the automatic (AUTO)
functioning is chosen. Moving it instead onto the right, the
functioning of the machine becomes manual (MAN):
a. If the selector (12) is in position (AUTO) the machine activates
and deactivates all the working functions in an automatic mode
(see under paragraph “WORKING IN AUTOMATIC MODE”).
b. If the selector (12) is in position (MAN) every function of the
machine has to be activated or deactivated manually (see under
paragraph “WORKING IN MANUAL MODE”).
FORWARD AND BACKWARD MOVEMENT
It is recommendable 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 (5) clockwise to switch on the machine.
3. Check the charge level of the batteries on the display (1).
4. Release the parking brake. If the brake was inserted, the signal
lamp (17) would be switched on (see under paragraph
"EMERGENCY-PARKING BRAKE”).
5. Bring the selector (12) in central position (BREAK WASHING) 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.
6. Select the driving sense with the selector (8).
7. Press onto the accelerator pedal placed on the right side to start
the machine.
8. Adjust the driving speed in forward choosing the slow one (at the
maximum you can reach 4,5km/h - 2,8mph) or, pressing the same
selector (9) upwards, the faster one (at the maximum you can
reach 7 km/h - 4,35mph) can be obtained.
9. In backward movement, when the machine is moving, an
intermittent warning device is activated.
The machine is equipped with an automatic system that reduces the
speed when the drive direction is changed. The speed reduction is as
higher as sharper is the curve.
The speed returns again normally as soon as the machine gets out from
the curve and it runs along straight paths.
HORN
The machine is equipped with a horn which is activated pressing the
push button (6).
WORKING BRAKE
The machine is equipped with a hydraulic braking system that acts on
the rear wheels.
To brake it is sufficient to press the pedal placed at the left side of the
steering column releasing instead the accelerator pedal.
EMERGENCY-PARKING BRAKE
In case of an emergency pull the lever of the emergency and parking
brake (1) placed on the left side of the seat.
On the instrument board the signal lamp (17) comes on which signals
that the parking brake is inserted.
To release the parking brake press the button (2) placed at the final part
of the brake lever (1) and simultaneously lower it to the end.

13
AUTOMATIC SQUEEGEE LIFTING WHEN GOING BACKWARDS
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.
WORKING IN AUTOMATIC MODE
The automatic operation is useful to simplify the operator’s work.
1. Activate the machine (see under paragraph “STARTING OF THE
MACHINE”) putting the selector (12) into the left position to
choose the automatic function (AUTO).
2. Check that the lever (10) 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”).
3. Selecting the sense of drive in forward with the selector (8),
pressing the accelerator pedal and adjusting the speed of the
forward movement with the selector (9), the machine starts to
proceed and in automatic mode all the working functions are
activated. In fact, automatically both the brushes base as 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.
Selecting the backward movement with the selector (8) 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 switched off and both the
brushes base as the squeegee are lifted.
Pressing again the pedal, the machine starts to move again and in
automatic mode all the working functions are reactivated.
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.
Activate the machine (see under paragraph “STARTING OF THE
MACHINE”) positioning the selector (12) to the right to choose the
manual mode (MAN).
TO CARRY OUT THE WASHING WITH ONLY THE BRUSHES:
1. Activate the selector (14) of up/down of the brushes base to lower
the brushes. Once that it is lowered, the brushes begin to turn. The
signal lamp (22) indicates that the brushes base is in the working
position, while the signal lamp (23) signals that the brushes are
turning.
2. Press the switch (11) to open the solenoid valve and permit the
detergent solution to lower onto the brushes. The signal lamp (24)

WORKING ADJUSTMENTS
Both in automatic as in manual mode, during the first metres check:
1. 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”).
2. that the squeegee adjustment guarantees a perfect drying result
(see under paragraph “ADJUSTMENT OF THE SQUEEGEE”).
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 (10) placed
on the upper part of the side instrument board, rotating
counterclockwise to increase it and clockwise to reduce it up to closure
of the flow.
BRUSHES PRESSURE ADJUSTMENT
Using the knob (4) it is possible to adjust the brushes pressure on the
floor on three preset levels. On the display (1) the pressure previously
set can be seen, by pressing the button (3).
The adjustment is made this way on both manual and automatic mode.
To avoid overloading the brushes motors it is bette to decrease the
brushes pressure when switching from smooth to rough floors (i.e.
concrete floors).
ELECTRIC PROTECTION
The machine is equipped with an electronic system of amperemetric
protection for the principal working functions. This control device
disconnects the function of the interested component that shows the
problem and indicates on the display (1) the corresponding alarm, for
example ”AL01”, “AL03”.
The last two figures indicate the code number of the alarm.
To restore the functioning of the component, turn off and on again the
machine acting upon the key switch. If the alarm persists, please
contact the authorized technical assistance.
OVERFLOW DEVICE
In order to avoid serious damages to the suction motors, the machine is
equipped with a float that intervenes when the recovery tank is full,
closing the suction, the switching on of the signal lamp (20) for the
signaling of the full recovery tank and consequently to the drying stop.
When this happens, it is necessary to empty the recovery tank (see
under paragraph “RECOVERY TANK EMPTYING AND CLEANING”).
SELECTING AND WORKING ON 3S “SOLUTION SAVING SYSTEM”
MODE
To work with the 3S “Solution
Saving System”
select a water
carriage using the knob (1).
On manual mode the detergent solution flow is constant and related to
the water carriage selected using the knob.
On automatic mode the carriage of the detergent solution flow changes
accordingly to the speed, up to the maxim set, in order to have a
constant water carriage per square meter.
If the machine is steady then the speed will be zero and no water will
come out.
STOP OF THE MACHINE AFTER CLEANING OPERATION
IN AUTOMATIC OR MANUAL WORKING MODE:
1. At the end of the washing cycle put the selector (12) into the
central position (BREAK WASHING). In this way automatically the
brushes lift, the solenoid valve shuts down and it is possible to
finish the drying operation.
2. 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 (the transfer can be carried out
also if the pedal is never lifted, in this case the squeegee gets lifted
and the suction stop automatically after 15 seconds).
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 positioning to the left the selector (12) into position (AUTO) one
can start again to work in an automatic mode.
B. by positioning to the right the selector (12) into position (MAN)
the machine re-establishes the functions pre-set manually.
