Battery Charging - Nilfisk-ALTO SCRUBTEC R 253 Bedienungshandbuch

BATTERY CHARGING

NOTE
Charge the batteries when there is only one flashing segment displayed in the battery symbol (48-C), or at the end of the
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 raised until the battery charging cycle is over.
WARNING!
Pay close attention when charging WET CELL batteries, 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.
1. Drive the machine to the appointed recharging area.
2. Ensure that the machine is off and the operator key (41) is turned to "O".
3. Lift the cover (29) and check that the recovery tank (17) is empty; if not, empty it using the drain hose (26).
4. Close the cover (18).
5. Grasp the handle (35) and carefully lift the recovery tank assembly (17).
6. (For WET CELL batteries only) Check the level of electrolyte inside the batteries. If necessary, unscrew the caps and top up.
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 battery charger voltage rating must
be 24 V.
2. Disconnect the battery connector (6) 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 (6).
5. Connect the battery connector (9) to the machine.
6. Disengage the support rod (36), then grasp the handle (35) and carefully lower the recovery tank assembly (17).
Battery charging with battery charger installed on the machine
1. Plug the battery charger cable (21) into the electrical mains (the 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.
When the first or second segment from the left in the battery symbol (48-L) is flashing, this means that the battery charger is
charging the batteries.
When the third segment from the left in the battery symbol (48-L) is flashing, this means that the battery charger is finishing the
battery charging cycle.
2. When all segments of the battery symbol (48-L) are steadily lit, the battery charging cycle is complete.
3. Disconnect the battery charger cable plug (21) from the mains and place it in its holder (20).
4. Disengage the support rod (36), then grasp the handle (35) and carefully lower the recovery tank assembly (17).
5. Now the machine is ready to be used.
NOTE
For further information about the operation of the battery charger (22), see the relevant Manual.
