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 cy-
cles.
To remove the battery 8 press the unlocking but-
tons 7 and pull out the battery downwards. 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 man-
ner.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.
Changing the Tool (see figure A)
Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
The drill spindle is locked when the On/Off
switch 11 is not pressed. This makes quick, con-
venient and easy changing of the tool in the drill
chuck possible.
Open the keyless chuck 1 by turning in rotation
direction , until the tool can be inserted. Insert
the tool.
Firmly tighten the collar of the keyless chuck 1
by hand in rotation direction
action ("click") is no longer heard. This automat-
ically locks the chuck.
The locking is released again to remove the tool
when the collar is turned in the opposite direc-
tion.
