possible to check the state of charge when the power tool is
not in operation.
Press the button for the battery charge indicator   or 

 to

show the state of charge. This is also possible when the bat-
tery is removed.
If no LED lights up after pressing the button for the battery
charge indicator, then the battery is defective and must be
replaced.

Changing the tool (see figure A)

u

Remove the battery from the power tool before carry-
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.

u

When working with an application tool, pay attention
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 

(11)

 onto the square drive of the

tool holder 

(1)

.

Due to the way the system operates, the application tool

(11)

 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.

Automatic shutdown ABR (ABR = Auto Bolt Release) (see
figure C)

The ABR function automatically shuts down the power tool
when the bolt nut is released. The automatic shutdown pre-
vents the bolt nut from falling down when released. You can
use the "Automatic shutdown (ABR)" button 

(5)

 to activate

and deactivate ABR. The LED for "Automatic shutdown
(ABR)" 

(7)

 lights up when ABR is activated. The previous

setting is retained when the battery is changed.

Starting Operation

Inserting the battery

Set the rotational direction switch 

(8)

 to the centre position

to protect the power tool from being switched on accident-
ally.
Push the charged battery 

(3)

 into the base of the power tool

until the battery is securely locked.

Set the rotational direction (see figure B)

The rotational direction switch 

(8)

 is used to change the ro-

tational direction of the power tool. However, this is not pos-
sible while the on/off switch 

(9)

 is being pressed.

Right rotation:

 To drive in screws and tighten nuts, press

the rotational direction switch 

(8)

 through to the left stop.

Left Rotation:

 To loosen and unscrew screws and nuts,

press the rotational direction switch 

(8)

 through to the right

stop.

Switching on/off

To 

start

 the power tool, press and hold the on/off switch

(9)

.

The lamp 

(6)

 lights up when the on/off switch 

(9)

 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 

(9)

.

Adjusting the Speed

You can adjust the speed of the power tool when it is on by
pressing in the on/off switch 

(9)

 to varying extents.

A light pressure on the on/off switch 

(9)

 results in a low rota-

tional speed. Increased pressure on the switch causes an in-
crease in speed.

Practical advice

u

Only apply the power tool to the screw/nut when the
tool 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. Maximum torque is
achieved after an impact duration of 6–10 seconds. After
