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.
Rotating the Auxiliary Handle (see figure A)
The auxiliary handle 10 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 9 in anticlockwise direction and
set the auxiliary handle 10 to the required
position. Then tighten the wing bolt 9 again
in clockwise direction.
Adjusting the Drilling Depth (see figure B)
The required drilling depth X can be set with the
depth stop 11.
– Press the button for the depth stop adjust-
ment 8 and insert the depth stop into the
auxiliary handle 10.
The knurled surface of the depth stop 11
must face downward.
– 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 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,
tools without SDS-plus are used (e.g., drills
with cylindrical shank). For these tools, a key-
less chuck or a key type drill chuck are required.
Changing the Key Type Drill Chuck
To work with tools without SDS-plus (e.g., drills
with cylindrical shank), a suitable drill chuck
must be mounted (key type drill chuck or key-
less chuck, accessories).
Inserting the Key Type Drill Chuck
(see figure C)
– Clean the shank end of the adapter shank
and apply a light coat of grease.
– Insert the key type drill chuck with the adapt-
er shank into the tool holder with a turning
motion until it automatically locks.
– Check the locking effect by pulling the key
type drill chuck.
Removing the Key Type Drill Chuck
– Push the locking sleeve 3 toward the rear
and pull out the key type drill chuck 12.
