Adjusting the Drilling Depth on the Dust Extrac-
tion Attachment (see figure L)
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 30 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 31 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 31 further over the telescopic pipe 29 of the dust
extraction attachment than required, so that as much as
possible of the scale 29 on the telescopic pipe remains
visible.
Retighten the wing bolt 30 again. Loosen the clamping
screw 27 on the depth stop of the dust extraction
attachment.
Move the depth stop 28 on the telescopic pipe 29 in
such a manner that the clearance X shown in the figure
corresponds with the required drilling depth.
Tighten the clamping screw 27 in this position.

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.
