 Prevent dust accumulation at the workplace. Dust can
easily ignite.
 Warning! Danger of fire! Do not work metal or wooden
materials with the dust extraction mounted. Hot metal
chips can self-ignite or ignite parts of the dust extraction.
Note: Do not use the dust extraction 14 when chiselling or
screwdriving.
The dust extraction 14 retracts while working, so that the dust
collector is always kept close to structural surface being
drilled. The dust extraction automatically switches on and off
with the power tool.
To achieve optimum extraction results, please observe the
following notes:
– The drilling tool being used may not project over the dust
collector 17 or 30 (Example for an SDS-plus drill bit: Max.
total length approx. 160 mm, working length approx.
100 mm).
– Pay attention that the dust collector faces flush against the
workpiece or the wall. At the same time, this makes work-
ing at a right angle easier.
– After reaching the requested drilling depth, first pull the
drill bit out of the drill hole and then switch the machine
off.
– Check the condition of the filter element 24 regularly. Re-
place a damaged filter element immediately.
Mounting/Removing the Dust Extraction (see figure F)
– To remove the dust extraction, push the release button 10
and pull off the dust extraction toward the front.
If required, pivot the auxiliary handle 12 to the side.
– To mount the dust extraction 14, slide it via the guide
grooves 22 onto the support guide of the machine until it
can be heard to engage.
Integrated Dust Extraction with Dust Box (see figure G)
The filling level of the dust box 9 can easily be checked
through the transparent flap 23.
Empty the dust collector in good time, otherwise the suction
performance will be impaired.
– For removal of the dust box 9, push the two unlocking but-
tons 11 and pull the dust box downward out of the dust ex-
traction 14.
– Before opening the dust box 9, gently strike or tap it
against a firm surface to loosen the dust from the filter ele-
ment 24.
– Open the dust box flap 23 on the bottom side and empty
the dust box.
– Shut the dust box flap 23 and reinsert the dust box from
below into the dust extraction 14 until it can be heard to
engage.
– Check the filter element 24 for damage. Replace it imme-
diately when damaged.
External Dust Extraction (see figure H)
For dust extraction with a vacuum cleaner, the adapter box 25
(accessory), which is inserted into the dust extraction 14 in-
stead of the dust box 9, is required.
1 609 92A 24G | (14.6.16)
– For removal of the dust box 9, push the two unlocking but-
tons 11 and pull the dust box downward out of the dust ex-
traction 14.
– Insert the adapter box 25 from below into the dust extrac-
tion until it can be heard to engage.
– Place a vacuum hose 27 (accessory) onto the vacuum con-
nection 26. Connect the vacuum hose 27 with a vacuum
cleaner (accessory). An overview for the connection of
various vacuum cleaners can be found at the end of these
instructions.
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 (see figure I)
The required drilling depth X can be set with the depth stop
28.
– 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 adjustment of the
drilling depth.
– Without switching the power tool on, apply it firmly to the
drilling location. The SDS-plus drilling tool must face
against the surface.
– Push the button for depth stop adjustment 16 and adjust
the depth stop 28 so that the clearance X in the figure cor-
responds with your requested drilling depth.
Adapting the Dust Extraction to the Tool Length
(see figure J)
For more convenient working with short drilling tools, the
length of the dust extraction 14 can be adapted.
– Push and hold button 13 and slide the telescopic guide 15
into the dust extraction 14 until the dust collector is close
to the tip of the drilling tool.
– To draw out the telescopic guide, push button 13 again.
Dust Collector for Drill Bits (see figure K)
– To change the dust collector 17, push the release button
29 and pull the dust collector out of the dust extraction.
– To insert the dust collector 17, push it from above into the
dust extraction 14 until it can be heard to engage.
Dust Collector for Core Bits (Accessory) (see figure L)
For drilling with core bits, the dust collector for drill bits 17
must be replaced against a special dust collector for core bits
30 (accessory). When using the dust collector for core bits,
the adapter box 25 (accessory) must be used for dust extrac-
tion, not the dust box 9.
– If required, remove the dust collector for drill bits 17.
– To insert the dust collector for core bits 30, push it from
above into the dust extraction until it can be heard to en-
gage.
– For removal of the dust collector for core bits 30, push the
latching projection 31 outward and pull off the dust collec-
tor upward.
