6.3 Intended use
This charger charges the 28 V Li-Ion battery that was supplied with the battery appliance for
the M28/V28 system. This appliance may only be used as specified and intended.
6.4 Mains connection
Only connect to single-phase alternating current and only to the mains voltage specified
on the rating plate. It can also be connected to sockets without an earth contact as it is built
in accordance with protection category II.
6.5 Li-Ion-battery
For safety reasons, the batteries are discharged when they are delivered (air transport
regulation). The battery must be charged completely before first use.
LED charging status indication
If the battery is not used for a longer period of time, it switches to idle mode. The battery must
be re-activated (charged) in order to be used again.
The charging status can be checked by pressing the button on the battery (see illustration).
The battery can remain in the battery tool for this but the battery tool must be switched off at
least 1 minute before (otherwise the indication will be inaccurate). The number of
illuminated LEDs indicates the charging status.
As a matter of principle, the following applies: If the battery tool does not work after inserting
the battery, plug the battery into the charger to check it. The indications on the battery and
the charger then provide information on the battery condition.
You can continue to work with reduced power at lower temperatures. To ensure that the
appliance is ready to use, the battery must be fully
charged after use.
