Battery Charging (see figure A)
f 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
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)
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.
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 n, until the tool can be inserted. Insert
the tool.
Firmly tighten the collar of the keyless chuck 2
by hand in rotation direction o. 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)
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 n. Please note that the se-
curing screw has a left-hand thread.
