6. INSTALLATION INFORMATION

6.1 BATTERY PREPARATION
( 

! 

) 

The technical features of the batteries used

must match those indicated in the technical featu-
res section. Using different batteries may cause se-
rious damage to the machine or may require them
to be charged more frequently.

(



)

During installation or when performing any

type of battery maintenance, the operator must be
equipped with adequate safety accessories to pre-
vent accidents. Work far from open flames, do 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.

6.2 BATTERY INSTALLATION AND CONNEC-
TION 
( 

! 

)

These operations must be carried out by spe-

cialised personnel.
Disconnect the Anderson connector of the battery

wiring from the Anderson connector of the machine
wiring. Always hold the connectors with the hands
and never pull on the cables.

(



) 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 explosion!

After checking that all the controls on the panel are
in position “0” or at rest, connect the battery con-
nector to the machine connector. 

( 

! 

)

Close the battery compartment making sure

not to crush any wires.

6.3 SETTING OF THE ELECTRONIC BOARD
FOR THE SECURITY STOP OF THE BRUSH
MOTOR

In order to avoid the complete discharge of the bat-
teries, the machine is provided with a safety device.
When charge of the batteries goes below the sa-
fety threshold, the electronic card (Photo G) stops
the operation of the brush motor.

(

☞

) The operator must stop its work and re-

charge 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 G - 1).
To reach the electronic card it is necessary to re-
move the plastic cap placed on the control panel;
through the hole it is possible to reach the selector
with a screwdriver;

(

☞

) 

Put the selector to the right if the machine is

provided with  GEL batteries, or to the left if the
machine is provided with Pb-Acid batteries (Photo G
- 1 ).

6.4 MACHINE PREPARATION
( 

! 

)

Before starting to work, wear non-slip shoes,

gloves and any other personal protection device in-
dicated by the supplier of the detergent used or
considered necessary based on the operating envi-
ronment.

(

☞

)

Do the following before starting to work. Refer

to the relative sections for a detailed description of
these steps:
check the battery charge level and charge, if ne-
cessary.
Mount the brushes or scraper disks (with the abra-
sive disks) that are suitable for the surface and
work involved.
Mount the squeegee, check that it is solidly atta-
ched and connected to the suction hose and that
the drying blades are not too worn.
Make sure that the recovery tank is empty. If not,
empty it completely.
Check and completely close the detergent solution
