Changing the Tool
The dust protection cap 2 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care
that the dust protection cap 2 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales serv-
ice.
Inserting SDS-plus Drilling Tools (see figure D)
The SDS-plus drill chuck allows for simple and
convenient changing of drilling tools without the
use of additional tools.
– Clean and lightly grease the shank end of the
tool.
– Insert the tool in a twisting manner into the
tool holder until it latches itself.
– Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus
drilling tool can move freely. This causes a cer-
tain radial run-out at no-load, which has no ef-
fect on the accuracy of the drill hole, as the drill
bit centres itself upon drilling.
Removing SDS-plus Drilling Tools
(see figure E)
– Push back the locking sleeve 3 and remove
the tool.
Inserting Drilling Tools without SDS-plus
(see figure F)
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 chiselling.
– Insert a key type drill chuck 12 (see "Chang-
ing the Key Type Drill Chuck", page 20).
– Open the key type drill chuck 12 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 12 and clamp
the tool uniformly.
– Turn the mode selector switch 7 to the "drill-
ing" position.
Bosch Power Tools
Removing Drilling Tools without SDS-plus
(see figure G)
– Turn the sleeve of the key type drill chuck 12
with the drill chuck key in anticlockwise di-
rection until the drilling tool can be removed.
Dust Extraction with the Dust Extrac-
tion Attachment (Accessory)
Mounting the Dust Extraction Attachment
(see figure H)
For dust extraction, the dust extraction attach-
ment (accessory) is required. When drilling, the
dust extraction attachment retracts so that the
attachment head is always close to the surface
at the drill hole.
– Press the button for depth stop adjustment 8
and remove the depth stop 11. Press button
8 again and insert the dust extraction attach-
ment into the auxiliary handle 10 from the
front.
– Connect an extraction hose (diameter
19 mm, accessory) to the extraction sleeve
13 of the dust extraction attachment.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Adjusting the Drilling Depth on the Dust Ex-
traction Attachment (see figure I)
The required drilling depth X can also be adjust-
ed 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 adjustment of the drill-
ing depth.
– Loosen the wing bolt 17 on the dust extrac-
tion attachment.
– Without switching the power tool on, apply it
firmly to the drilling location. The SDS-plus
drilling tool must face against the surface.
