GETTING STARTED
BATTERY OPERATION
Before operating the device for the fi rst time remove the T 8.0 A
fuse from the packaging and place it in the fuse holder.
This fuse prevents the device from being switched on accidentally
during transportation.
After the fuse has been inserted the charging status display does
not function properly until the battery has been fully discharged
once.
Battery operation is only possible if the battery is charged suffi ciently.
Otherwise the MSK 125 cannot be switched on.
Note
Once the battery has fully discharged it must be recharged
immediately to avoid damage to the battery.
Charging starts automatically after the device has been connected
to the mains. The battery cannot overcharge thanks to a protection
switch.
Battery operation is signalled by a red LED next to the
button.
The battery capacity is 6.45 Ah.

ion battery.
