Dust Extraction with the Dust 
Extraction Attachment (Accessory)

Mounting the Dust Extraction Attachment 
(see figure F)

For dust extraction, the dust extraction attachment

(accessory) is required. When drilling, the dust extrac-

tion attachment retracts so that the attachment head

is always close to the surface at the drill hole.
Press the button for depth stop adjustment 

9

 and

remove the depth stop 

10

. Press button 

9

 again and

insert the dust extraction attachment into the auxiliary

handle 

11

 from the front.

Connect an extraction hose (diameter 19 mm, acces-

sory) to the extraction sleeve 

15

 of the dust extraction

attachment.
The vacuum cleaner must be suitable for the material

being worked.
When vacuuming dry dust that is especially detrimen-

tal to health or carcinogenic, use a special vacuum

cleaner.

Adjusting the Drilling Depth on the Dust Extrac-
tion Attachment (see figure H)

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 

1

. Otherwise, the movability of

the SDS-plus drilling tool can lead to incorrect adjust-

ment of the drilling depth.
Loosen the wing bolt 

19

 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 

20

 of the dust extraction

attachment 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 

20

 further over the telescopic pipe 

18

 of

the dust extraction attachment than required, so that

as much as possible of the scale 

18

 on the telescopic

pipe remains visible.
Retighten the wing bolt 

19

 again. Loosen the clamp-

ing screw 

16

 on the depth stop of the dust extraction

attachment.
Move the depth stop 

17

 on the telescopic pipe 

18

 in

such a manner that the clearance

X

 shown in the fig-

ure corresponds with the required drilling depth.
Tighten the clamping screw 

16

 in this position.

Operation

Starting Operation

¢

Observe correct mains voltage! The voltage
of the power 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.

Setting the Operating Mode

The operating mode of the power tool is selected with

the mode selector switch 

8

.

Note: 

Change the operating mode only when the

machine is switched off! Otherwise, the machine can

be damaged.
To change the operating mode, push the release but-

ton 

7

 and turn the mode selector switch 

8

 to the

requested position until it can be heard to latch.

Reversing the Rotational Direction

The rotational direction switch 

4

 is used to reverse the

rotational direction of the machine.

¢

Actuate the rotational direction switch 4 only
when the machine is at a standstill.
Right rotation: 

Turn the rotational direction

switch 

4

 to the stop in the position 

.

Left rotation: 

Turn the rotational direction switch

4

 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 

5

.

To 

switch off

 the machine, release the On/Off

switch 

5

.

hammer drilling

 in con-

crete or stone

Position for 

drilling

 without impact in 

wood, metal, ceramic and plastic as well 

as for screwdriving and thread cutting.

Vario-Lock

 position for adjustment of
