Removing the battery (see figure A)
To remove the battery (8), press the release button (7) and
pull the battery downwards out of the power tool. Do not
use force to do this.
Changing the Tool
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Regularly clean the power tool's air vents. The motor's
u
fan can draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
GDR 12 V-110:
Inserting the application tool (see figure B)
Pull the locking sleeve (2) forward, guide the application tool
(1) into the tool holder up to the stop and release the locking
sleeve (2) to lock the application tool.
Screwdriver bits (15) can be inserted using a universal bit
holder with ball catch (14).
Removing
Pull the locking sleeve (2) forward and remove the applica-
tion tool.
GDS 12 V-115: (see figure C)
When working with an application tool, pay attention
u
that the application tool is connected securely to the
tool holder. When the application tool is not securely
connected with the tool holder, it can come off during ap-
plication.
Slide the application tool (16) onto the square drive of the
tool holder (1).
Due to the way the system operates, the application tool
(16) will move around slightly in the tool holder(1); this has
no influence on the function/safety.
Operation
Method of Operation
The tool holder (1) (with the application tool) is driven by an
electric motor via a gear and impact mechanism.
The working procedure is divided into two phases:
Screwing in and tightening (impact mechanism in action).
The impact mechanism is activated as soon as the screwed
connection runs tight and load is therefore put on the motor.
The impact mechanism then converts the power of the mo-
tor to steady rotary impacts. When loosening screws or nuts,
the process is reversed.

Starting Operation
Inserting the Battery
Set the rotational direction switch (9) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (8) into the handle until you feel it engage and it is
flush with the handle.
Set the rotational direction (see figure D)
The rotational direction switch (9) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (10) is being pressed.
Right rotation: To drive in screws and tighten nuts, press
the rotational direction switch (9) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (9) through to the right
stop.
Switching on/off
To start the power tool, press and hold the on/off switch
(10).
The lamp (3) lights up when the on/off switch (10) is lightly
or fully pressed, meaning that the work area is illuminated in
poor lighting conditions.
To switch off the power tool, release the on/off switch (10).
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (10) to varying extents.
A light pressure on the on/off switch (10) results in a low ro-
tational speed. Increased pressure on the switch causes an
increase in speed.
Preselecting the speed/impact rate
You can use the button (6) to preselect the required speed/
impact rate in two stages. Press the button (6) repeatedly
until the required setting appears in the speed indicator (5).
The selected setting will be saved.
The required speed/impact rate is dependent on the mater-
ial and the work conditions and can be determined by prac-
tical trials.
Switching the "PowerLight" lamp on/off
Press the button (4) to activate the lamp (3). To switch off
the lamp (3), press the button (4) again.
Battery charge indicator
When the on/off switch (10) is pressed in halfway or com-
pletely, the battery charge-control indicator (11) indicates
the charge condition of the battery for several seconds. The
indicator consists of three green LEDs.
