Assembly
Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
Operate your machine only with the auxiliary
handle 10.
Rotating the Auxiliary Handle (see figure A)
The auxiliary handle 10 can be set to any position
for a secure and low-fatigue working posture.
Turn the wing bolt for adjustment of the auxiliary
handle 9 in anticlockwise direction and set the
auxiliary handle 10 to the required position. Then
tighten the wing bolt 9 again in clockwise direc-
tion.
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 adjustment 8
and insert the depth stop into the auxiliary han-
dle 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 mova-
bility of the SDS-plus drilling tool can lead to in-
correct 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
correspond with the desired drilling 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 keyless
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 keyless
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 adapter
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.
Changing the Tool
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 protection cap 2 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales service.
Inserting SDS-plus Drilling Tools (see figure D)
The SDS-plus drill chuck allows for simple and
convenient changing of drilling tools without the
use of additional tools.
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.
As a requirement of the system, the SDS-plus
drilling tool can move freely. This causes a cer-
tain radial run-out at no-load, which has no effect
on the accuracy of the drill hole, as the drill bit
centres itself upon drilling.
Removing SDS-plus Drilling Tools (see figure E)
Push back the locking sleeve 3 and remove the
tool.
