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.
Pull out the depth stop until the distance between the
tip of the drill bit and the tip of the depth stop corre-
spond with the desired drilling depth X.
The knurled surface of the depth stop 11 must face
downward.
Selecting the Tool Holder
For hammer drilling, SDS-plus drilling tools that can
be inserted into the SDS-plus tool holder 1 are
required.
For drilling without impact in wood, metal, ceramic
and plastic as well as for screwdriving and tapping,
use non-SDS-plus drilling tools (e. g., drill bits with
cylindrical shank). A keyless drill chuck is required
for such drilling tools.
☞
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 tool holder 1 can easily be exchanged
against the quick change keyless chuck 12.
Changing the Tool Holder
Dismounting the SDS-plus Tool
Holder or the Quick change keyless
chuck (see figure B)
Pull the lock ring of the tool holder 4 firmly in the
direction of the arrow, hold it in this position and pull
off the tool holder 1 or the keyless replacement
chuck 12 toward the front.
After removing, protect the tool holder 1 or the quick
change keyless chuck 12 against contamination.
Lightly lubricate the engaging grooves, if required.
Mounting the SDS-plus Tool Holder
or the Quick change keyless chuck
Grasp the tool holder 1 or the keyless replacement
chuck 12 completely with your hand. Slide the tool
holder 1 or the keyless replacement chuck 12 with a
turning motion onto the drill chuck mounting until a
distinct latching noice is heard.
The tool holder 1 or the quick change keyless chuck
12 is automatically locked. Check the locking effect
by pulling the tool holder.

Changing the Tool
With the SDS-plus tool holder, simple and convenient
tool changing is possible without additional aids.
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 accu-
racy of the drill hole, as the drill bit centres itself
upon drilling.
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 pro-
tection cap 2 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 C)
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.
Removing SDS-plus Drilling Tools
(see figure D)
Push back the locking sleeve 3 and remove the tool.
Inserting Drilling Tools without SDS-
plus (see figure E)

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 the quick change keyless chuck 12.
Firmly hold the retaining ring of the quick change
keyless chuck 12. Open the quick change keyless

Check the tight seating by pulling the tool.
☞
Note: If the tool holder was opened to the
stop, then the latching noise possibly may be
heard while closing the tool holder and the
tool holder will not close.
In this case, turn the front sleeve 13 once in
the opposite direction of the arrow. After-
wards, the tool holder can be closed (tight-
ened) again.
