Assembly
Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
Operate your machine only with the auxilia-
ry handle 17.
Rotating the Auxiliary Handle (see figure A)
The auxiliary handle 17 can be set to any posi-
tion for a secure and low-fatigue working pos-
ture.
– Turn the wing bolt for adjustment of the aux-
iliary handle 16 in anticlockwise direction
and set the auxiliary handle 17 to the re-
quired position. Then tighten the wing bolt
16 again in clockwise direction.
Adjusting the Drilling Depth (see figure B)
The required drilling depth X can be set with the
depth stop 18.
– Press the button for the depth stop adjust-
ment 15 and insert the depth stop into the
auxiliary handle 17.
The knurled surface of the depth stop 18
must face downward.
– Insert the SDS-plus drilling tool to the stop
into the SDS-plus tool holder 3. Otherwise,
the movability of the SDS-plus drilling tool
can lead to incorrect adjustment of the drill-
ing 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 drill-
ing 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, ce-
ramic 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.
