Changing the Tool



Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport 
and storage, remove the battery from the power tool. 

There is danger of injury when unintentionally actuating 
the On/Off switch.



Regularly clean the power tool’s air vents. 

The motor’s 

fan will draw the dust inside the housing and excessive ac-
cumulation of powdered metal may cause electrical haz-
ards.

GDR 12V-110:
Inserting (see figure B)

Pull the locking sleeve 

2

 forward, push the insert tool to the 

stop into the tool holder 

1

 and release the locking sleeve 

2

 to 

lock the insert tool.

Screwdriver bits 

15

 can be inserted using a universal bit hold-

er with ball lock 

14

.

Removing

Pull the locking sleeve 

2

 forward and remove the insert tool.



When working with an application tool, pay attention 
that the application tool is connected securely on the 
tool holder. 

When the application tool is not securely con-

nected with the tool holder, it can come off during applica-
tion.

Slide the application tool 

16

 onto the square drive of the tool 

holder 

1

.

With this system, there will be a slight amount of play around 
the application tool 

16

 after connecting securely to the tool 

holder 

1

; this has no influence on the function/safety.

Operation

Method of Operation

The tool holder 

1

 with the 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 thus load is put on the motor. In this 
instance, the impact mechanism converts the power of the 
motor 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 centre position to 

protect the power tool against accidental starting.

Insert the charged battery 

8

 from the front into the base of the 

power tool until the battery is securely locked.

Reversing the rotational direction (see figure D)

The rotational direction switch 

9

 is used to reverse the rota-

tional direction of the machine. However, this is not possible 
with the On/Off switch 

10

 actuated.

Right rotation:

 For driving in screws and tightening nuts, 

press the rotational direction switch 

9

 through to the left 

stop.

Left Rotation:

 For loosening and unscrewing screws and 

nuts, press the rotational direction switch 

9

 through to the 

right stop.

Switching On and Off

To save energy, only switch the power tool on when using it.

To 

start

 the machine, press the On/Off switch 

10

 and keep it 

pressed.

To 

switch off

 the machine, release the On/Off switch 

10

.

Adjusting the Speed

The speed of the switched-on power tool can be variably ad-
justed, depending on how far the On/Off switch 

10

 is 

pressed.

Light pressure on the On/Off switch 

10

 results in a low rota-

tional speed. Further pressure on the switch results in an in-
crease in speed.

Preselecting the Speed/Impact Rate

With the button 

6

 you can preselect the required speed/im-

pact rate in 2 stages. Press the button 

6

 repeatedly until the 

desired setting appears in the speed indicator 

5

. The selected 

setting will be saved.

The required speed/impact rate depends on the material and 
the working conditions, and can be determined through prac-
tical testing.

Switching the “PowerLight” On/Off

To switch the “PowerLight” 

3

on

, press button 

4

. To switch 

the “PowerLight” 

3

off

, press button 

4

 again.

Battery Charge-control Indication

The battery charge-control indicator 

11

 consists of three 

green LEDs, and indicates the charge condition of the battery 
for a few seconds when the On/Off switch 

10

 is pressed half-

way or fully.

Temperature Dependent Overload Protection

In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the 
permitted battery temperature range, the power output is re-
duced or the power tool is switched off. The power tool will 
not run at full power output again until the permitted battery 
temperature has been reached.

Working Advice



Apply the power tool to the screw/nut only when it is 
switched off. 

Rotating tool inserts can slip off.

The torque depends on the impact duration. The maximum 
achieved torque results from the sum of all individual torques 
achieved through impact. The maximum torque is achieved
