not short-circuit the battery poles, do not generate
sparks and do not smoke.
The batteries are normally supplied full of acid so-
lution (for the Pb-Acid type) and ready for use. In
any case, follow the steps indicated in the manual
supplied with the battery and carefully follow the
instructions regarding safety and operating proce-
dures.

BATTERY CONNECTION

These operations must be carried out by specia-
lized personnel.
Check that all the controls on the panel are in po-
sition "0" or at rest.
Photo G show connection diagram of the batteries
for DC 24V machines.
Attach the battery wiring to the battery,
connecting the terminals only on the poles
marked with the same symbol (red wiring
"+", black wiring "-")!
A battery short-circuit may cause an explo-
sion!
Close the battery compartment making sure not
to crush any wires.
Photo H - 2 show the correct connection of the
batteries for DC 24V machines.
5.2 BATTERY CHARGER CONFIGURA-
TION
We recommend to call the assistance centre or
a technician if you have problems with the setting
given.
The machine is equipped with a battery charger
configurated for GEL batteries
If the operator whish to use Pb-Acid battery, it is
necessary change the battery charger settings as
follows:
DISPLAY OF THE BATTERY CHARGER SETTINGS
The battery charger settings are shown by the blin-
king of the LED indicator when the battery charger
is switching on:
- the RED LED indicator ( Photo O - 2 ) flashes
2 times = the battery charger is set for PB-Acid
batteries
- the GREEN LED indicator ( Photo O - 3 ) flashes 2
times = the battery charger is set for GEL batteries
The battery charger settings will be displayed even
if batteries are not connected.
DIP-SWITCH CONFIGURATION FOR PC-
ACID/GEL BATTERY CHARGING CURVE
To set the charging curve type for Pb-Acid or GEL
batteries it is necessary to operate on a dip-switch
placed inside the battery charger ( Photo O -4 ).
The dip-switch available for the setting of the char-
ging curve is on the control card that is placed
behind the lower panel of the battery charger (
Photo O - 1 ). It is also possible to reach the dip-
switch by removing the plastic cap ( Photo O - 5 ).
Starting from left to right, the dip-switch available
for the setting of the charging curve is the first one,
that is indicated by number 1 in dip-switch SW1 (
Photo O - 6 ).

5.3 SETTING
BOARD FOR THE SECURITY STOP OF THE
BRUSH MOTOR
In order to avoid the complete discharge of the
batteries, the machine is provided with a safety
device. When charge of the batteries goes below
the safety threshold, the electronic card (Photo I)
stops the operation of the brush motor.
☞ The operator must stop its work and recharge
the batteries.
Before the first use of the machine it is necessary
to set the electronic card for the operation of the
machine with Pb-Acid or Gel batteries through the
selector (Photo I - 1).
To reach the electronic card it is necessary to ex-
tract the hour meter (Photo I); through the lodging
hole of lodging of the hour meter it is possible to
reach the selector with a screwdriver;
☞ Put the selector to the right if the machine is
provided with Pb-Acid batteries, or to the left if
the machine is provided with GEL batteries (Photo
I - 1 ).
