Fully Automatic Spindle Locking
(Auto-Lock)
The drill spindle is locked when the On/Off
switch 4 is not pressed.
This makes quick and easy changing of the tool
in the drill chuck possible.
The locked drill chuck enables retightening of
projecting screws by using the switched-off ma-
chine as a screwdriver.
Reversing the Rotational Direction
Operate the
switch 5 only at a standstill.
a b
a
Right Rotation (
Turn the rotational direction switch through to the
left stop (normal operation: drilling, screwdriving,
etc.).
b
Left Rotation ( )
Press the rotational direction switch through to
the right stop (for loosening and unscrewing
screws and nuts).
Setting the Torque
Carry out a practical test to determine with which
of the 15 settings of the torque setting ring 2 the
screws are driven flush into the material.
Low setting, e. g., small screws, soft
1
materials.
High setting, e. g., large screws, hard
15
materials.
With the correct setting, the clutch disengages as
soon as the screw is driven flush into the material
or the set torque is reached. Select a higher set-
ting when driving out screws, or set to the "Drill-
ing" symbol.

rotational direction
The rotational direction
switch 5 is used to re-
verse the rotational direc-
tion of the machine. How-
ever, this is not possible
with the On/Off switch 4
actuated.

Drilling and Impact Drilling
Drilling
Set the torque setting ring 2 to the "Drill-
ing" symbol.
Hammer Drilling (GSB 12 – 24 VE-2)
Set the torque setting ring 2 to the
"Hammer Drilling" symbol.
Replacing the Drill Chuck
Before any work on the machine itself, re-
move the battery.
The locking screw 14 secures the drill chuck
against loosening from the drill spindle. Fully
open the chuck and completely unscrew the
locking screw 14 (Note: left-handed thread!)
(see figure E
Loosening the Drill Chuck
(see figure
Place the machine on a stable surface (e. g.
workbench). Hold the machine firmly and loosen
the chuck by turning to the left, as when unscrew-
ing a screw ( ). Loosen a tight chuck by giving
the long end of the Allen key 13 a sharp blow.
Tightening the Drill Chuck
(see figure
The drill chuck is mounted in reverse order ( ).
Operating Instructions
Soft grip
The gripping surface 10 on the rear of the handle
(soft grip) reduces the danger of slipping and
thereby improves the grip on the machine and the
handling.
At the same time, the rubber coating achieves a
vibration-reducing effect.
Tips
Use only screwdriver bits that fit properly in the
head of the screw.
When driving in larger and/or longer screws in
hard material, it is advisable to drill a pilot hole
first.
For drilling in metal, use only perfectly sharp-
ened HSS drills. The appropriate quality is
guaranteed by the Bosch accessories pro-
gram.
