Battery Charging (see figure A)
Use only the battery chargers listed on the
accessories page. Only these battery charg-
ers are matched to the lithium ion battery of
your power tool.
Note: The battery is supplied partially charged.
To ensure full capacity of the battery, complete-
ly charge the battery in the battery charger be-
fore using your power tool for the first time.
The lithium ion battery can be charged at any
time without reducing its service life. Interrupt-
ing the charging procedure does not damage the
battery.
The Li-ion battery is protected against deep dis-
charging 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
WARNING
On/Off switch after the ma-
chine has been automatically switched off. The
battery can be damaged.
To remove the battery 7, press the battery un-
locking button 12 and pull the battery out of the
power tool toward the rear. Do not exert any
force.
For charging, the battery 7 can also remain in
the power tool. During the charging procedure,
the power tool cannot be switched on. Press the
On/Off switch 11 to check the charge condition
of the battery, see Section "Battery Charge-con-
trol Indication".

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.
Observe the notes for disposal.
Changing the Tool (see figure B)
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 2 by turning in rotation
direction , until the tool can be inserted. Insert
the tool.
Firmly tighten the collar of the keyless chuck 2
by hand in rotation direction . This automati-
cally locks the drill chuck.
The locking is released again to remove the tool
when the collar is turned in the opposite direc-
tion.
Replacing the Drill Chuck
(see figures D–F)
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.
Removing the Securing Screw (see figure D)
The keyless chuck 2 is secured with a securing
screw 14 against unintentional loosening from
the drill spindle. Completely open the keyless
chuck 2 and unscrew the securing screw 14 in
rotation direction . Please note that the se-
curing screw has a left-hand thread.
