Removing SDS-plus Drilling Tools
(see figure E)
Push back the locking sleeve 3 and remove the tool.
Inserting Drilling Tools without SDS-plus
Note: Do not use tools without SDS-plus for hammer
drilling or chiselling! Tools without SDS-plus and their
drill chucks are damaged by hammer drilling or chisel-
ling.
Insert a key type drill chuck 13 (see "Changing the
Key Type Drill Chuck", page 16).
Open the key type drill chuck 13 by turning until the
tool can be inserted. Insert the tool.
Insert the chuck key into the corresponding holes of
the key type drill chuck 13 and clamp the tool uni-
formly.
Set the selector switch 7 to the "Drilling" symbol.
Removing Drilling Tools without SDS-plus
Turn the sleeve of the key type drill chuck 13 with the
drill chuck key in anticlockwise direction until the drill-
ing tool can be removed.
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 detrimental
to health or carcinogenic, use a special vacuum cleaner.
Adjusting the Drilling Depth on the Dust
Extraction Attachment (see figure G)
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. Otherwise, the movability of the
SDS-plus drilling tool can lead to incorrect adjustment
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
With the selector switch for drilling/hammer drilling 7,
the operating mode of the machine is selected.
Note: Change the operating mode only when the
machine is switched off! Otherwise, the machine can
be damaged.
To change the operating mode, press the release but-
ton 8 and turn the drilling/hammer drilling selector
switch 7 to the desired position until it can be heard
to latch.
Position for hammer drilling in concrete
or stone as well as for chiselling (chisel-
ling only with the MV 200 accessory).
Position for drilling without impact in
wood, metal, ceramic and plastic as well
as for screwdriving and thread cutting.
