Battery Charging
Note: Charge the battery when only one LED of the battery symbol is ashing, 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
ames. 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 uid
leakages. The battery uid is corrosive. If it comes in contact with skin or eyes, rinse
thoroughly with water and consult a physician.
1. Raise the recovery tank.
2. (For WET batteries only) Check the level of electrolyte inside the batteries. If necessary, unscrew the
caps and top up.
3. When the correct level is restored, close the caps and clean the tops of the batteries.
Charging the Batteries with an External Battery Charger
1. Check that the external battery charger is suitable by referring to the relevant Manual. The external
battery charger voltage rating must be 24 V.
2. Disconnect the red battery connector (A) which is tted with a handle, and connect it to the external
battery charger.
3. Connect the external battery charger to the electrical mains.
4. After charging, disconnect the external battery charger from the electrical mains and from the battery
connector.
5. Connect the red battery connector (A) to the connector (B) xed to the machine.
WARNING: Never connect the external battery charger to the opposing part of the connector (B)
xed to the machine. The electronic system could be irreparably damaged.
