Removing the Battery
To remove the rechargeable battery, press the battery re-
lease button and pull the battery out. Do not use force to do
this.
The rechargeable battery has two locking levels to prevent
the battery from falling out if the battery release button is
pressed unintentionally. The rechargeable battery is held in
place by a spring when fitted in the power tool.
Battery charge indicator
The green LEDs on the battery charge indicator indicate the
state of charge of the battery. For safety reasons, it is only
possible to check the state of charge when the power tool is
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.
The state of charge of the battery is also displayed on the
user interface (see "Status indicators", page 39).
