Assembly
Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
Operate your machine only with the auxilia-
ry handle 10.
The auxiliary handle 10 can be set to any posi-
tion for a secure and low-fatigue working pos-
ture.
Turn the bottom part of the auxiliary handle 10
in counterclockwise direction and swivel the
auxiliary handle 10 to the desired position. Then
retighten the bottom part of the auxiliary handle
10 by turning in clockwise direction.
Adjusting the Drilling Depth (see figure A)
The required drilling depth X can be set with the
depth stop 11.
Press the button for the depth stop adjustment
9 and insert the depth stop into the auxiliary
handle 10.
Insert the SDS-plus drilling tool to the stop into
the SDS-plus tool holder 1. 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.
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, ce-
ramic 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 ex-
changed 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 re-
placement chuck 12 toward the front.
After removing, protect the tool holder 1 or the
quick change keyless chuck 12 against contami-
nation. 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 replace-
ment 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.
