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 packagins on top of each other.
UNPACKING THE MACHINE
1. Remove the external packing.
2. Before moving the machine from the pallet, it is necessary to
unblock the parking brake that blocks the traction motor wheel.
To do this, keep the lever (1) lifted. With the delivery of the
machine we also supply a cord that permits the lever operation
(1). After having moved the machine, take off the cord and keep
it for eventual re-use.
When the parking brake is released manually, for example when the
machine has to be moved without batteries, avoid covering slopes
and do not park on them either.
3. Release the machine from the wooden brackets by moving it
backwards, as indicated in the figure, avoiding heavy contacts to
mechanical parts.
Keep the pallet and the wooden brackets for an eventual transport.
The portable slope is not included in the packaging.
ROLLBAR
The machine is provided with a tipping rollbar.
To rotate the rollbar from an open to a closed position, or the other
way around, work on blocks (1).
ACCESS TO THE BATTERY COMPARTMENT
Open the rollbar.
To reach the battery compartment lift the seat base by grabbing the
handle (1).
If the machine is equipped with the optional 3SD water system, it is
necessary to take off the support of the detergent tanks after lifting
the seat base.
To remove the support, unscrew the 6 fixing screws.
INSTALLING THE BATTERIES
The standard machine is provided with the batteries set on lead/acid.
For different settings see chapter “BATTERY SETTINGS”.
Batteries 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.
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.

10
2. Connect the terminals, respecting the polarities, avoiding
contact with other parts that could create short circuit.
BATTERIES CHARGE LEVEL INDICATOR
The battery charge level is visualized on the display with its respective
symbol (see "CONTROLS DISPLAY").
When the last segment of charge starts blinking, the
battery is almost low and the suction and brushes
functions are disabled.
When even the last segment of charge turns off, the
battery is completely low and the machine stops.
CHARGING THE BATTERIES
1. Plug the connector (2) of the battery recharger into the battery
connector (1).
2. Proceed for the recharging.
Once that the battery recharging is completed:
3. Disconnect the connector of the battery recharger from the
battery connector (1).
4. Connect instead the machine connector (3).
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.
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 nuts (8), adjust the height then fix the
adjustment by tighten the nuts (8).
ASSEMBLING AND DISASSEMBLING THE SPLASH GUARDS
For the splash guards cleaning, it is necessary to take off the two
metal covers.

11
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. Take off the cover from the brushes base.
For the assembly it is necessary to proceed inversely with above-
mentioned operation.
ADJUSTING THE SPLASH GUARDS
When the brushes base is lowered on the floor the splash guards have
to slightly touch the floor. To adjust them proceed as follows:
1. Loosen the rings (2).
2. Turn the knob (1) clockwise to raise the splash guards or
counterclockwise to lower them.
3. Fasten the ring (2).
ASSEMBLING THE BRUSHES
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 lock the brushes
rotating them as in the picture below.
For a longer life of the brushes we suggest to invert daily their
position. Whenever brushes result to be deformed we suggest
reassembling them in the same position, in order to avoid that the
different inclination of the bristles causes excessive motor overload
or troublesome vibrations.

do it see chapter “AUTOMATIC DISASSEMBLY OF THE BRUSHES”).
CLEANING THE SQUEEGEE
Keeping the squeegee clean guarantees always the best drying result.
For its cleaning it is necessary to:
1. Take off the squeegee hose (4) from the coupling.
2. Disassemble the squeegee (3) from its support (1) loosening the
stud bolts (2) and making them slide inside the slots up to release
them.
3. Clean with care the internal part of the squeegee inlet eliminating
eventual dirt residuals.
4. Clean with care the squeegee rubbers.
5. Reassemble all parts.

cap
8. Keep the valve open.
9.
It is possible to drain the
solution tank also by
unscrewing the cap (3).
TWO-MONTHLY MAINTENANCE
FRONT SQUEEGEE RUBBER CHECK
Check the wear of the squeegee rubber and eventually replace it.
For the replacement it is necessary to:
1. Take off the squeegee (see under paragraph “SQUEEGEE
CLEANING”).
2. Disassemble the rear part of the squeegee (see under paragraph
“REAR SQUEEGEE RUBBER CHECK”).
3. Unscrew the wing nuts (1) and take off the front rubber holder
blade (2).
4. Replace the front rubber (3).
To reassemble the squeegee repeat reverse the operations above
mentioned.
SIX-MONTHLY MAINTENANCE
SPLASH GUARD RUBBER CHECK
With the brushes assembled, the splash guards must slightly touch
the floor. If they are worn, they have to be replaced. Just release the
lever coupler placed in the rear part of the brushes base group from
the ring placed at the free extremity of the metal strip to take off the
rubbers and to reinsert the new ones (see under paragraph “SPLASH
GUARD ASSEMBLY”). This operation has to be carried out for both
splash guards”).
