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, charge the
battery for at least 3 hours in the battery charger
before using 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 8, press the battery un-
locking button 13 and pull the battery out of the
power tool toward the rear. Do not exert any
force.
For charging, the battery 8 can also remain in the
power tool. During the charging procedure, the
power tool cannot be switched on. Press the
On/Off switch 12 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 manner.
Observe the notes for disposal.

Changing the Tool (see figure B)
Before any work on the machine (e. g., main-
tenance, tool change, etc.) as well as during
transport and storage, set the rotational di-
rection switch to the centre position. Unin-
tentional actuation of the On/Off switch can
lead to injuries.
The drill spindle is locked when the On/Off
switch 12 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
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., main-
tenance, tool change, etc.) as well as during
transport and storage, set the rotational di-
rection switch to the centre position. Unin-
tentional actuation of the On/Off switch can
lead to injuries.
The keyless chuck 2 is secured with a securing
screw 15 against unintentional loosening from
the drill spindle. Completely open the keyless
chuck 2 and unscrew the securing screw 15 in ro-
tation direction
. Please note that the securing
screw has a left-hand thread.
If the securing screw 15 is seated tightly, apply a
screwdriver to the screw head and loosen the se-
curing screw by giving a blow onto the handle of
the screwdriver.
