CHARGING PROCEDURE
NotE:
Before using the tool, read the
instruction book carefully.
1. ChargiNg YoUr BattErY PaCK
The battery charger supplied is matched to the
Li-Ion battery installed in the machine. Do not
use another battery charger.
The Li-Ion battery is protected against deep
discharging. When the battery is empty,
the machine is switched off by means of a
protective circuit: The tool holder no longer
rotates.
In a warm environment or after heavy use, the
battery pack may become too hot to permit
charging. Allow time for the battery to cool
down before recharging.
When the battery is charged for the first time
and after prolonged storage, the battery
will only accept approximately 60% charge.
However, after several charge and discharge
cycles the battery will accept a 100% charge.

supply and the green light (2) will illuminate.
Slide the battery pack (a) into the charger to

battery at normal ambient temperature
will take approximately 45 min to reach full
charge. When charging is completed the green
light (2) will illuminate while the red light (3)
is off.
