Battery Charging

Use only the chargers listed in the technical data. Only
u
these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
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.
Inserting the application tool (see figure B)
GDR 12V-110:
Pull the locking sleeve (2) forward, guide the application tool
(1) into the tool holder as far as it will go 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).
Inserting the application tool (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.
GDS 12V-115:
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.
Removing
Pull the locking sleeve (2) forward and remove the applica-
tion tool.

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.
