– Press the button for depth stop adjustment 

12

 and remove 

the depth stop 

13

. Press button 

12

 again and insert the 

dust extraction attachment into the auxiliary handle 

14

from the front.

– Connect an extraction hose (diameter 19 mm, accessory) 

to the extraction sleeve 

22

 of the dust extraction attach-

ment.

The vacuum cleaner must be suitable for the material being 
worked.

When vacuuming dry dust that is especially detrimental to 
health or carcinogenic, use a special vacuum cleaner.

Adjusting the Drilling Depth on the Dust Extraction 

Attachment (see figure K)

The required drilling depth

X

 can also be adjusted when the 

dust extraction attachment is mounted.

– Insert the SDS-plus drilling tool to the stop into the SDS-

plus tool holder 

3

. Otherwise, the movability of the SDS-

plus drilling tool can lead to incorrect adjustment of the 
drilling depth.

– Loosen the wing bolt 

26

 on the dust extraction attach-

ment.

– Without switching the power tool on, apply it firmly to the 

drilling location. The SDS-plus drilling tool must face 
against the surface.

– Position the the guide pipe 

27

 of the dust extraction at-

tachment in its holding fixture in such a manner that the 
head of the dust extraction attachment faces against the 
surface to be drilled. Do not slide the guide pipe 

27

 further 

over the telescopic pipe 

25

 of the dust extraction attach-

ment than required, so that as much as possible of the 
scale 

25

 on the telescopic pipe remains visible.

– Retighten the wing bolt 

26

 again. Loosen the clamping 

screw 

23

 on the depth stop of the dust extraction attach-

ment.

– Move the depth stop 

24

 on the telescopic pipe 

25

 in such 

a manner that the clearance

X

 shown in the figure corre-

sponds with the required drilling depth.

– Tighten  the  clamping  screw 

23

 in this position.

Operation

Starting Operation



Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the 

nameplate of the machine. Power tools marked with 

230 V can also be operated with 220 V.

Products sold in AUS and NZ only

: Use a residual current de-

vice (RCD) with a rated residual current of 30 mA or less.

Setting the operating mode

The operating mode of the power tool is selected with the 
mode selector switch 

11

.

– To change the operating mode, push the release button 

10

and turn the mode selector switch 

11

 to the requested po-

sition until it can be heard to latch.

Note: 

Change the operating mode only when the machine is 

switched off! Otherwise, the machine can be damaged.

Reversing the rotational direction

The rotational direction switch 

7

 is used to reverse the rota-

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

9

 actuated.

Right rotation: 

Turn the selector switch for drilling/ham-

mer drilling 

7

 on both sides to the stop in the position 

.

Left rotation: 

Turn the selector switch for drilling/ham-

mer drilling 

7

 on both sides to the stop in the position 

.

– Set the direction of rotation for hammer drilling, drilling 

and chiselling always to right rotation.

Switching On and Off

– To 

start

 the machine, press the On/Off switch 

9

.

– To 

lock

 the On/Off switch, keep it pressed and additionally 

push the lock-on button 

8

.

– To 

switch off

 the machine, release the On/Off switch 

9

. 

When the On/Off switch 

9

 is locked, press it first and then 

release it.

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

Setting the Speed/Impact Rate

The speed/impact rate of the switched on power tool can be 
variably adjusted, depending on how far the On/Off switch 

9

is pressed.
Light pressure on the On/Off switch 

9

 results in low speed/

impact rate. Further pressure on the switch increases the 
speed/impact rate.

Overload Clutch



If the tool insert becomes caught or jammed, the drive 

to the drill spindle is interrupted. Because of the forces 

that occur, always hold the power tool firmly with both 

hands and provide for a secure stance.



If the power tool jams, switch the machine off and 

loosen the tool insert. When switching the machine on 

with the drilling tool jammed, high reaction torques 

can occur.
