Removing the Battery
The battery (5) is equipped with two locking levels to pre-
vent the battery from falling out if the battery release button
(6) is pressed unintentionally. As long as the battery is inser-

To remove the battery (5), press the release button (6) and
pull the battery out of the power tool. Do not use force to
do this.

not in operation.
Press the button for the battery charge indicator or
show the state of charge. This is also possible when the bat-
tery is removed.
If no LED lights up after pressing the button for the battery
charge indicator, then the battery is defective and must be
replaced.
