Adjusting the Drilling Depth (see figure B)
The required drilling depth X can be set with the
depth stop 12.
Press the button for the depth stop adjustment
11 and insert the depth stop into the auxiliary
handle 13.
The knurled surface of the depth stop 12 must
face upward.
Insert the SDS-plus drilling tool to the stop into
the SDS-plus tool holder 3. Otherwise, the mov-
ability of the SDS-plus drilling tool can lead to
incorrect adjustment of the drilling depth.
Pull out the depth stop until the distance be-
tween the tip of the drill bit and the tip of the
depth stop correspond with the desired drilling
depth X.
Selecting Drill Chucks and Tools
For hammer drilling and chiselling, SDS-plus
tools are required that are inserted in the
SDS-plus drill chuck.
For drilling without impact in wood, metal,
ceramic and plastic as well as for screwdriving
and thread cutting, tools without SDS-plus are
used (e.g., drills with cylindrical shank). For
these tools, a keyless chuck or a key type drill
chuck are required.
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.
The SDS-plus quick change chuck 2 can easily
be replaced against the quick change keyless
chuck 1 provided.

Inserting the Quick Change Chuck
(see figure D)
Before inserting, clean the quick change chuck
and apply a light coat of grease to the shank end.
Grasp the SDS-plus quick change chuck 2 or the
quick change keyless chuck 1 completely with
your hand. Slide the quick change chuck with a
turning motion onto the drill chuck mounting 15
until a distinct latching noise is heard.
The quick change chuck is automatically locked.
Check the locking effect by pulling the quick
change chuck.
Changing the Tool
The dust protection cap 4 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care
that the dust protection cap 4 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend
having this carried out by an after-sales
service.
Inserting SDS-plus Drilling Tools
(see figure E)
The SDS-plus drill chuck allows for simple and
convenient changing of drilling tools without the
use of additional tools.
Insert the SDS-plus quick change chuck 2.
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
certain radial run-out at no-load, which has no
effect on the accuracy of the drill hole, as the
drill bit centres itself upon drilling.
Removing SDS-plus Drilling Tools
(see figure F)
Push back the locking sleeve 5 and remove the
tool.
