INTRODUCTORY COMMENT
Thank you for having chosen our machine. This floor cleaning machine is used for the industrial and civil cleaning and is able to clean any type of
floor. During its advance movement, the combined action of the brush and the detergent solution removes the dirt which is aspirated through the
rear suction assembly, giving a perfectly dry surface.
The machine must be used only for such purpose. It gives the best performance if it is used correctly and maintained in perfect efficiency. We
therefore ask you to read this instruction booklet carefully whenever difficulties arise in the course of the machine’s use. In case of need, we ask you
to contact our service department for all advice and servicing as may prove necessary.

BEFORE USE
HANDLING OF THE PACKED MACHINE
The machine is supplied with suitable packing foreseen for fork lift
truck handling.
For the package dimensions please look at the “TECHNICAL
DESCRIPTION” table.
Do not place more than 2 packings on top of each other.
UNPACKING OF THE MACHINE
1. Remove the external packing.
2. Unscrew the brackets that secure the machine to the pallet.
3. Move the machine backwards, as indicated in figure, avoiding
heavy contacts to mechanical parts.
4. Keep the pallet for eventual transport.
The portable slope is not included in the packaging.
BATTERY INSTALLATION AND SETTING OF THE BATTERY TYPE
This machine is equipped with two batteries at 12V in serial
connection, placed in its appropriate compartment under the
recovery tank and must be handled using suitable lifting equipment
(due to weight and coupling system).
The batteries must be in accordance with CEI 21-5 Norms.
The connection of the batteries' cables has to be carried out by
specialized staff, because the inversion of polarity causes the damage
of the electrical components.
Before the machine is supplied with power, check that the red cable
is connected to the + pole of the battery.
For batteries installation proceed as follows:
1. Take off the squeegee hose (1).
2. Take off the suction cover (2) after turning the blocking levers
(3).
3. Take off the recovery tank (4).
4. Place the batteries in its compartment.
5. Connect the terminals, respecting the polarities, avoiding
contact with tools that could create short circuit.
6. Reassemble all parts.
The machine and the signal lamp of the battery charge level foresee
the use of traditional lead batteries.
If the machine is equipped with the display, check the battery
setting on it (1).
In case of GEL batteries installation, it is necessary to carry out a
specific adjustment. Please contact the authorized technical
assistance.
BATTERY CHARGER
Be 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.

11
BATTERIES CHARGING
Take the machine to a levelled surface.
Plug in batteries connector (1) placed in the rear part of the machine,
to connector (2) of the battery recharger.
ON-BOARD BATTERY RECHARGER (OPTIONAL)
If the machine is equipped with the on-board battery recharger (see
under "OPTIONAL ACCESSORIES”) please refer to the instructions of
the constructor of this accessory what the recharging operations
concern.
The battery recharger is connected directly to the battery poles.
During the recharging operations a device is activated which does not
permit the machine's functioning.
The main cable of the battery recharger has a maximum length of
two meters (6.5 ft.) and must be connected to a single-phase socket
type CEE 7/7.
BATTERIES CHARGING WITH ON-BOARD BATTERY CHARGER
(OPTIONAL)
Bring the machine on a leveled surface near to a single-phase socket
(within 2m, 6.5 ft.) with tension 230V, frequency 50Hz (for USA 120V,
60Hz), nominal current 10A.
Switch off the switches of the brushes motor, suction motor and of
the solenoid valve.
Insert the plug into the mains socket.
At the end of the recharging, take off the plug from the mains
socket.
BATTERIES CHARGE LEVEL INDICATOR
If the machine is not provided with a display, when switching on
the signal lamp of the battery charge level (2) will come on.
When the signal lamp is in green colour it means that the battery
charge level is sufficient for the functioning of the machine.
If the signal lamp is in red colour it means that the battery charge
level is insufficient for the functioning of the machine and it is
necessary to recharge immediately the batteries (see under
"BATTERIES CHARGING”).
If the machine is equipped with a display, on the display (1) the
following indication of the battery charge level is digital and
indicates the percentage of the battery charge. 100 is the maximum
charge, down to a minimum of 10, indicating every 10% decrease.
When the charge level reaches 20%, the display starts blinking
indicating the end of the battery charge.
After a few seconds from the four blinking ‘’----’’ dashes, the brushes
motor stops automatically. With the remaining charge it is anyhow
possible to finish the drying operation before proceeding to the
recharge.
HOUR METER (IF EQUIPPED WITH A DISPLAY)
The machine is equipped with an hour meter located on the same
display of the battery charge level indicator (1). Keeping the button
(2) pressed for more than 3 seconds, the first data indicates the
working hours and after a few seconds the working minutes are
shown.
SQUEEGEE ASSEMBLING
With the squeegee support lowered, slide the two stud bolts (1)
placed on the upper part of the squeegee inside the slots on the
support. Block the squeegee by rotating the lever (2) clockwise.
Insert the squeegee hose (3) into its coupling, respecting its position
as indicated in the figure.

12
ADJUSTING THE SQUEEGEE HEIGHT
The squeegee must be adjusted in height depending on the rubber
wear. In order to guarantee a perfect drying during the operation, the
lower blade of the rear squeegee rubber (4) must work slightly bent
backwards (operator side) in uniformed way in all its length.
Acting clockwise upon the two registers (5) it is possible to increase
the bending of the rubber. Acting counterclockwise it is possible to
decrease the rubber bending.
A label placed near the two registers (5) indicates rotation sense to
increase or reduce the height.
Note: The wheels of the squeegee support must be adjusted through
the registers (5) at the same height so that the squeegee works
parallel to the floor.
ADJUSTING THE SQUEEGEE INCLINATION
In case of need, to increase the rubber bending in the central part, it
is necessary to tilt the squeegee rotating counterclockwise the
register (6). To increase the rubber bending on the squeegee
extremities, rotate the register clockwise.
SPLASH GUARD ASSEMBLING
SPRING-LOCKING TYPE
The two splash guards have to be assembled onto the brushes base
group. Insert the metal strips inside the suitable slots present on the
rubber. Place the round hole at the flat extremity of the strip onto

SINGLE BRUSH VERSION

13
TWO-BRUSHES VERSION
To unlock the brush, perform the same operations and rotate the
brush the opposite way as for the locking.
For a longer life of the brushes we suggest to invert daily their
position. Whenever brushes were deformed we suggest to reassemble
them in the same position, avoiding that the different inclination of
the bristles causes excessive motor overload or troublesome
vibrations.
AUTOMATIC BRUSH RELEASE
Only for the models with the 50 brush base it is possible to release
the brush as follows:
1. Lift the brush base by pressing the pedal (10).
2. Turn on the brush switch (3).
3. Press the drive control levers (7).
4. Press the release button (11).
5. Release the drive control levers (7).
In this way the brush automatically releases itself from the brush
base.
RECOVERY TANK
Check that the cover of the suction filter (1) is correctly secured, after
rotating the levers and that the suction motor hose (2) is correctly
connected.
Verify also that the squeegee hose is correctly inserted into the seats
(3 and 4) and that the exhaust hose plug (5) placed in the front part
of the machine, is closed.
DETERGENT SOLUTION TANK
The solution tank is provided with an inspection opening. This permits
to clean the exit point of the detergent solution.
Be sure that the cap is well tightened after the cleaning.
The capacity of the detergent solution tank is indicated in the
technical data.
Open the screw plug (1) placed in the rear 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.

7. Acting upon the brush base lifting pedal (9) lower the brush
base.
8. Acting upon the solution valve lever (7) open and adjust the
solution detergent flow.
The water starts to flow automatically when the brush motor is
activated.
On the instrument board the indicator of the solenoid valve
switch (5) will turn on.
9. Activating the levers drive control (6) the machine will start
moving, the brush starts to rotate, the solenoid valve activates
the water flow and the squeegee will start drying the floor.
10. During the first meters check that the detergent solution flow is
appropriate and that the squeegee adjustment guarantees a
perfect drying action.
3S SYSTEM “SOLUTION SAVING SYSTEM” (OPTIONAL)
The need of an increasing carefulness to the environment, and to the
abuse of polluting elements, such as detergents in the floor cleaning
machines, has brought us to the realization of a device which,
regardless from the capacity to use the machine by the operator,
keeps the minimum flow of the detergent solution constant, having
been properly calibrated by an expert technician. The best detergent
solution amount with this system will be the one which realizes the
minimum flow of detergent solution sufficient to clean correctly the
floor. For this reason the system is called “Solution Saving System”
abbreviated to “3S” system.
The system is composed by a hydraulic circuit parallel to the
traditional one which can be enabled or disabled directly from the
instrument board through a 3-position switch with the following
functions:
(1) = Position solution valve with traditional functioning with
variable water flow that differs by the opening of the solution valve.
(2) = Position STOP with functioning without flow (drying only).
(3) = Position 3S with functioning with optimal fixed flow.
The hydraulic circuit of the 3S system is independent and it is
provided with a proper filter which has to be cleaned regularly.
For the cleaning it is necessary to unscrew the plug as shown in the
figure and clean the inside filter with a water jet.
OVERFLOW DEVICE
In order to avoid serious damages to the suction motor, the machine
is equipped with a float that intervenes when the recovery tank is
full, closing the suction hose and stopping the suction.
When this happens, it is necessary to empty the recovery tank.
1. Hold the exhaust hose placed in the front part of the machine.
2. Take off the exhaust plug acting upon its lever and empty the
recovery tank into appropriate containers, according to the
standard norms for the liquid disposal.
EMPTYING DETERGENT SOLUTION
To empty the detergent solution remained in the solution tank:
1. Bring the machine to an appropriate place for tanks draining.
2. Unscrew the solution tank cap (1).
3. Unscrew the exhaust plug (2).
FORWARD MOVEMENT (IF EQUIPPED WITH TRACTION)
The traction of this machine is given through an electronically
controlled motor.

15
To move the machine, act upon the switch (1), then rotate the levers
drive control placed on the handle bar, in forward you obtain the
forward drive, in reverse the backwards movement is obtained. The
control acts in a progressive way, therefore it is possible to graduate
the speed depending on each requirement rotating the lever
whatever it is necessary. During reverse motion the speed is reduced.
STOP (IF EQUIPPED WITH TRACTION)
Releasing the levers drive control, the machine and the brush will
stop.
Moving the machine backwards, make sure that the squeegee is
lifted.
ADJUSTMENT OF THE BRUSH/ES PRESSURE PRESENT ON SOME
MODELS
Through the register (1) placed on the internal part of the front right
wheel, it is possible to adjust the brush/es pressure on the cleaned
surface.
By turning the wing nut clockwise the pressure increases, rotating the
wing nut counterclockwise, the pressure decreases.
This device allows a more efficient cleaning action also on very
difficult and dirty surfaces.
BRUSH/ES MOTOR OVERLOAD PROTECTION DEVICE (OPTIONAL)
If the machine is equipped with the amperemetric protection device
(see under "OPTIONAL ACCESSORIES"), this, in case of extended
overload of the brush/es motor, intervenes shutting it off.
Furthermore, on the display (1) appears an alarm ”AL01”. In case of
intervention of this device, check the brush/es pressure adjustment in
connection with the type of floor to be cleaned and if necessary,
reduce it.
To reset the brush/es motor, turn off the brush/es motor switch (5)
for a few seconds and turn it on again.
SIGNAL DETERGENT SOLUTION RESERVE (H2O ON THE DISPLAY)
When the indication H2O on the display appears, this means that the
detergent is getting low corresponding to 10% of the maximum
capacity of the solution tank.
STOP OF THE MACHINE AFTER CLEANING OPERATION
Before executing any type of maintenance:
1. Lift the brushes base acting upon the pedal (9).
2. Lift the squeegee acting upon the lever (8).
3. Turn off the brush motor, the suction motor and the solenoid
valve acting upon its switches.
