5.2 Operation
5.2.1 Commissioning
Checks and operations to be performed before starting daily work
Procedure
• Make sure the battery is in physically good condition.
• Make sure the terminals are correct (positive to positive and negative to negative)
and check that contacts on the battery terminal conducting system are secure.
• Check the terminal screw torques (M10 = 23 ±1 Nm) of the terminal conductors and
connectors.
• Re-charge the battery.
• Charge the battery.
Check completed.
5.2.2 Discharging the battery
Z
To achieve an optimum useful life avoid operational discharges of more than 60%
of nominal capacity.
Z
If the battery is discharged during operation by more than 80% of rated capacity the
useful life of the battery will reduce significantly. Fully or partially discharged
batteries must be re-charged immediately and not left unattended.
5.2.3 Charging the battery
WARNING!
The gases produced during charging can cause explosions
The battery gives off a mixture of oxygen and hydrogen (electrolytic gas) during
charging. Gassing is a chemical process. This gas mixture is highly explosive and
must not be ignited.
 Always disconnect the charger and truck before connecting or disconnecting the
charger and battery.
 The charger must be adapted to the battery in terms of voltage, charge capacity
and battery technology.
 Before charging, check all cables and plug connections for visible signs of damage.

Ventilate the room in which the truck is being charged.
 Battery cell surfaces must remain exposed during charging in order to ensure
sufficient ventilation, see truck operating instructions, chapter D, Charging the
Battery.
 Do not smoke and avoid naked flames when handling batteries.

Wherever an industrial truck is parked for charging there must be no inflammable
material or consumables capable of creating sparks within a minimum distance of
2 m from the truck.
 Fire protection equipment must be available.

Do not place any metallic objects on the battery.
 Always follow the safety regulations of the battery and charger station
manufacturers.
