The drill spindle is locked when the on/off switch 

(11)

 is not

pressed. This makes it possible to change the application
tool in the drill chuck quickly, conveniently and easily.
Open the keyless chuck 

(2)

 by turning it in the direction of

rotation 

➊

 until the tool can be inserted. Insert the tool.

Firmly tighten the keyless chuck 

(2)

 by turning it by hand in

the direction of rotation 

➋

. This will automatically lock the

drill chuck.

Dust/Chip Extraction

Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one’s
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.

u

Avoid dust accumulation at the workplace. 

Dust can

easily ignite.

Operation

Starting Operation

Inserting the battery
Note:

 The use of batteries unsuitable for your power tool can

lead to malfunctions or damage to the power tool.
Push the charged battery 

(7)

 into the base of the power tool

from the front until the battery is securely locked.

Setting the rotational direction (see figure B)

The rotational direction switch 

(10)

 is used to change the ro-

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

(11)

 is being pressed.

Right rotation:

 To drill and to drive in screws, press the ro-

tational direction switch 

(10)

 through to the left stop.

Left Rotation:

 To loosen and unscrew screws and nuts,

press the rotational direction switch 

(10)

 through to the

right stop.

Setting the Operating Mode

Drilling

GSR

Set the torque presetting ring 

(3)

 to the

"drilling" symbol.

GSB

Set the mode selector switch 

(4)

 to the

"drilling" symbol.

Screwdriving

GSR

Set the torque presetting ring 

(3)

 to the re-

quired torque.

GSB

Set the mode selector switch 

(4)

 to the "screw-

driving" symbol.

Impact drilling (GSB)

Set the mode selector switch 

(4)

 to the "impact

drilling" symbol.

Switching on/off

To 

start

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

(11)

.

The LED 

(9)

 lights up when the on/off switch 

(11)

 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 

(11)

.

Adjusting the Speed

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

(11)

 to varying extents.

A light pressure on the on/off switch 

(11)

 results in a low ro-

tational speed. Increased pressure on the switch causes an
increase in speed.

Preselecting torque (applies to screwdriving mode)

The torque presetting ring 

(3)

 can be used to pre-select the

required torque in 20 stages. Once the set torque has been
reached, the application tool will be stopped.

Mechanical gear selection

u

Only operate the gear selector (5) when the power
tool is not in use.

First gear:

Low speed range; for working with a large drilling diameter
or for screwdriving.

Second gear:

High speed range; for working with a small drilling diameter.

u

Always push the gear selector switch as far as it will
go.

 Otherwise, the power tool may become damaged.

Temperature-dependent overload protection

When used as intended, the power tool cannot be over-
loaded. In the event of overloading or the temperature
rising/falling outside the permitted operating temperature
range, the speed will be reduced. The power tool will not run
at full speed again until the permitted operating temperature
has been reached.

Fully automatic spindle lock (Auto-Lock)

The drill spindle, and therefore the tool holder, are locked
when the on/off switch 

(11)

 is not pressed.

This allows screws to be driven in even when the battery is
discharged and enables the power tool to be used as a
screwdriver.
