Battery Charging
A battery that is new or has not been used for a
longer period does not develop its full capacity
until after approx. 5 charging/discharging cycles.
To remove the battery
8
, press the battery un-
locking button
9
and pull the battery out of the
power tool toward the rear.
Do not exert any
force.
The battery is equipped with a NTC temperature
control which allows charging only within a tem-
perature range of between 0 °C and 45 °C. A long
battery service life is achieved in this manner.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.
