BATTERY CHARGING

NOTE
Charge the battery when only one LED of the battery symbol (45) is flashing, or at the end of each shift.
Keeping the batteries charged make their life last longer.
CAUTION!
When the batteries are discharged, charge them as soon as possible, as that condition makes their life shorter.
Check for battery charge at least once a week.
CAUTION!
If the machine is not equipped with on-board battery charger, choose an external battery charger suitable for the
type of batteries installed.
WARNING!
When using lead (WET) batteries, battery charging produces highly explosive hydrogen gas. Charge the
batteries in well-ventilated areas and away from naked flames.
Do not smoke while charging the batteries.
Keep the recovery tank lifted until the battery charging cycle is over.
WARNING!
Pay careful attention when charging lead batteries (WET) as there may be battery fluid leakages. The battery
fluid is corrosive. If it comes in contact with skin or eyes, rinse thoroughly with water and consult a physician.

Preliminary operations

1.
Drive the machine to the appointed recharging area.
2.
Ensure that the machine is off and the ignition key (41) has been removed.
3.
Lift the cover (34) and check that the recovery tank (33) is empty; if not, empty it using the drain hose (12).
4.
Close the cover (19).
5.

6.
For WET batteries only:
Check the level of electrolyte inside the batteries (36). If necessary, unscrew the caps and top up.
When the correct level is restored, close the caps and clean the tops of the batteries.
7.
Charge the batteries according to one of the following procedures, depending on the presence of the electronic battery charger
(4).
Charging the Batteries with an External Battery Charger
1.
Check that the external battery charger is suitable by referring to the relevant Manual. The battery charger voltage rating must
be 24 V.
2.
Disconnect the battery connector (8), which is fitted with a handle, and connect it to the external battery charger.
3.
Connect the battery charger to the electrical mains.
4.
After charging, disconnect the battery charger from the electrical mains and from the battery connector.
5.
Connect the battery connector (8) to the machine.
6.
Grasp the handle (16) and carefully lower the tank (33).
WARNING!
Never connect the external battery charger to the opposing part of the connector fixed to the machine. The
electronic system could be irreparably damaged.
Battery charging with battery charger installed on the machine
1.
Connect the battery charger cable (5) to the electrical mains. Electrical mains voltage and frequency must be compatible with
the battery charger values shown on the machine serial number plate (3).
NOTE
When the battery charger is connected to the electrical mains, all machine functions are automatically cut off.
2.
If the red LED on the battery charger inspection window (51) stays on, the battery charger is charging the batteries.
3.
When the yellow warning light turns on, the battery charging cycle is nearly completed.
4.
When the green warning light turns on, the battery charging is completed.
5.
When the battery charging is completed, disconnect the battery charger cable (6) from the electrical mains and wind it round
its housing (6).
