Battery Charging - Nilfisk SC450 Bedienungshandbuch

BATTERY CHARGING

NOTE
Charge the batteries when the yellow or red LED (45 or 46) turns on, or at the end of each working cycle.
CAUTION!
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!
WET 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.
Do not reinstall the recovery tank until the battery charging cycle is over.
WARNING!
Pay careful attention when charging WET 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. Turn off the machine by pressing the switches (41 and 42).
3. For WET batteries only:
• Remove the recovery water tank as shown in Use chapter. Check the level of electrolyte inside the batteries; if necessary,
top up through the caps.
• Leave all the battery caps open for next charging.
• If necessary, clean the upper surface of the batteries.
4. Charge the batteries according to one of the following procedures, depending on the presence of the battery charger (48).
Charging the Batteries with an External Battery Charger

11. (For WET batteries only): Reinstall the recovery tank.
Charging the Batteries with an (Optional) Battery Charger Installed on the Machine
12. Connect the battery charger cable (4) 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 (29)).
When the battery charger is connected to the electrical mains, all machine functions are automatically cut off.
If the red warning light (52) on the battery charger control panel stays on, the battery charger is charging the batteries.
