Removing the battery
The battery 5 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 6 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 unlocking button 6 and
pull out the battery toward the front. Do not exert any force.
Battery Charge-control Indication (see figure A)
The three green LEDs of the battery charge-control indicator

reasons, it is only possible to check the status of the charge
condition when the machine is at a standstill.
Press button 23 to indicate the charge condition. This is also
possible when the battery 5 is removed.
