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 6 press the unlocking but-
tons 5 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 8 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.
Bosch Power Tools
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.
Replacing the Drill Chuck
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 B)
The keyless chuck 1 is secured with a securing
screw 11 against unintentional loosening from
the drill spindle. Completely open the keyless
chuck 1 and unscrew the securing screw 11 in
rotation direction . Please note that the se-
curing screw has a left-hand thread.
Removing the Drill Chuck (see figure C)
Clamp the short end of an Allen key 12 into the
keyless chuck 1.
Place the machine on a stable surface (e. g. a
workbench). Hold the machine firmly and loos-
en the keyless chuck 1 by turning the Allen key
12 in rotation direction . Loosen a tight-seated
keyless chuck by giving the long end of the Allen
key 12 a light blow. Remove the Allen key from
the keyless chuck and completely unscrew the
keyless chuck.
Mounting the Drill Chuck (see figure D)
The keyless chuck is mounted in reverse order.
The drill chuck must be tightened with a
tightening torque of approx. 20–25 Nm.
Screw the securing screw 11 in anti-clockwise
direction into the opened keyless chuck. Always
use a new securing screw, as the threads are
covered with a thread-locking compound that
loses its effect after multiple usage.
