BATTERY CHARGING

NOTE
Charge the batteries when the yellow or red LED (62) turns on, or at the end of every working cycle.
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.
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.
While charging the battery, always keep the tank assembly open with the relevant stand (25).
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 (58) has been removed.
3. Lift the cover (20) and check that the recovery tank (19) is empty; if not, empty it using the drain hose (24).
4. Close the cover (20).
5. Carefully lift the recovery tank (44).
6. (For WET batteries only): Check the level of electrolyte inside the batteries (39). If necessary, unscrew the plugs (40) and top
up.
When the correct level is restored, close the plugs (40) 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 battery charger voltage rating must
be 24 V.
CAUTION!
The battery charger must be appropriate for the batteries installed on the machine.
2. Disconnect the battery connector (9) 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 (9).
5. Connect the battery connector (9) to the machine.
6. Carefully lower the recovery tank (44).
WARNING!
Never connect the battery charger to the opposing part of the connector fixed to the machine. The electronic
system could be irreparably damaged.
Charging the Batteries with an (Optional) Battery Charger Installed on the Machine
1. Connect the battery charger cable (41) to the electrical mains (the electrical mains voltage and frequency must be compatible
with the battery charger values shown on the machine serial number plate).
NOTE
When the battery charger is connected to the electrical mains, all machine functions are automatically cut off.
The red warning light (62) is on when the battery charger is charging the batteries.
The yellow warning light (62) is on when the battery charger is completing the battery charging.
2. When the green warning light turns on, the battery charging is completed.
3. Disconnect the battery charger cable (41) from the electrical mains and place it in its holder behind the battery charger.
4. Carefully lower the recovery tank (44).
5. Now the machine is ready to be used.
