Removing the Battery
The battery (5) is equipped with two locking levels to
prevent the battery from falling out if the battery
release button (6) is pressed unintentionally. As long as
the battery is inserted in the power tool, it is held in
position by means of a spring.
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.
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 to show the state of charge. This
is also possible when the battery 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.
