Assembly
f
Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
f
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
.
Loosen the wing bolt for the depth stop adjust-
ment
9
and insert the depth stop rod 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
.
Retighten the wing bolt for the depth stop ad-
justment

again.
The knurled surface of the depth stop
11
must
face upward.
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)
Turn the mode selector switch

temporarily to
the “drilling
”
position in order to lock the tool
holder.
Firmly turn the locking sleeve

in the direction
of the arrow and pull off the tool holder
1
or the
quick change keyless 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.
