Changing the Tool (see figure B)
Before any work on the power tool (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the center posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
The drill spindle is locked when the On/Off
switch 4 is not pressed. This makes quick, conve-
nient and easy changing of the tool in the drill
chuck possible.
Open the keyless chuck 3 by turning in rotation
direction
until the tool can be inserted. Insert
the tool.
Firmly tighten the collar of the keyless chuck 3 by
hand in rotation direction
tion ("click") is no longer heard. This automati-
cally locks the chuck.
The locking is released again to remove the tool
when the collar is turned in the opposite direction.
Replacing the Drill Chuck
Before any work on the power tool (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the center posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
Removing the Securing Screw (see figure C)
The keyless chuck 3 is secured with a securing
screw 13 against unintentional loosening from
the drill spindle. Completely open the keyless
chuck 3 and unscrew the securing screw 13 in ro-
tation direction
. Please note that the securing
screw has a left-hand thread.
Removing the Drill Chuck (see figure D)
Clamp the short end of a hex key 14 into the key-
less chuck 3.
Place the machine on a stable surface (e. g. a
workbench). Hold the machine firmly and loosen
the keyless chuck 3 by turning the hex key 14 in
rotation direction
. Loosen a tight-seated key-
less chuck by giving the long end of the hex key
14 a light blow. Remove the hex key from the key-
less chuck and completely unscrew the keyless
chuck.

Operation
Starting Operation
Inserting the Battery
until the locking ac-
Set the rotational direction switch 5 to the center
position in order to avoid unintentional starting.
Insert the charged battery 6 into the handle so
that it can be felt to engage and faces flush
against the handle.
Reversing the Rotational Direction
The rotational direction switch 5 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 4 actuated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 5 left to the
stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 5 through to the right stop.
Setting the Torque
The required torque can be preselected in 15
steps with the torque preselection ring 2. With
the correct setting, the insert tool is stopped as
soon as the screw is screwed flush into the ma-
terial or when the set torque is reached.
Select a higher setting when driving out screws,
or set to the "Drilling" symbol.
The drill chuck must be tightened with a
tightening torque of approx. 10–25 Nm.
Use only original Bosch O-pack batteries
with the voltage given on the type plate of
your machine. The use of other batteries can
lead to injuries and danger of fire.
