Set the rotational direction switch 5 to the centre
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 symbol "Drilling".
Gear Selection, Mechanical
The gear selector 1 can be actuated at stand-
still or when the machine is running. Howev-
er, this should not be done while operating
at full load or maximum speed.
Two speed ranges can be preselected with the
gear selector 1.
Gear I:
Low speed range; for screwdriving or working
with large drilling diameter.
Gear II:
High speed range; for working with small drilling
diameter.
If the gear selector 1 cannot be pushed through
to the stop, lightly turn the drill chuck with drill.
Setting the Operating Mode
Drilling and Screwdriving
Set the preselection ring 2 to the "Drill-
ing without impact" symbol.

Impact Drilling
(GSB 12 VE-2/GSB 14,4 VE-2/
GSB 18 VE-2/GSB 24 VE-2)
Set the preselection ring 2 to the "Impact drill-
ing" symbol.
Switching On and Off
To start the machine, press the On/Off switch 4
and keep it depressed.
To switch off the machine, release the On/Off
switch 4.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 4 is pressed.
Light pressure on the On/Off switch 4 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 4 is not pressed, the
drill spindle and thus the tool holder are locked.
This enables screws to be screwed in, even when
the battery is empty and allows for the machine
to be used as a screwdriver.
Run-on Brake
When the On/Off switch 4 is released, the chuck
brakes to a stop, thus preventing the run-on of
the tool.
When driving in screws, wait until the screw is
screwed in flush with the material and then release
the On/Off switch 4. By doing so, the head of the
screw does not penetrate into the material.

Working Advice

Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts
can slip off.
Soft Grip ("Comfort Zone")
The gripping surface (soft grip) 10 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.
