Note: The battery supplied is partially charged. To ensure full
capacity of the battery, completely charge the battery in the
battery charger before using your power tool for the first time.
The lithium-ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
 Do not continue to press the On/Off switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
Observe the notes for disposal.
Removing the battery
The battery 9 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 8 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 9, press the battery unlocking button 8
and pull the battery upward out of the power tool. Do not ex-
ert any force.
Battery Charge-control Indication (see figure F)
The three green LEDs of the battery charge-control indicator
25 indicate the charge condition of the battery 9. For safety
reasons, it is only possible to check the status of the charge
condition when the machine is at a standstill.
Press button 24 to indicate the charge condition. This is also
possible when the battery 9 is removed.
