Assembly
Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
Operate your machine only with the auxiliary
handle 11.
Rotating the Auxiliary Handle (see figure A)
The auxiliary handle 11 can be set to any position for
a secure and low-fatigue working posture.
Turn the bottom part of the auxiliary handle 11 in coun-
terclockwise direction and swivel the auxiliary handle
11 to the desired position. Then retighten the bottom
part of the auxiliary handle 11 by turning in clockwise
direction.
Adjusting the Drilling Depth (see figure B)
The required drilling depth X can be set with the
depth stop 10.
Press the button for the depth stop adjustment 9 and
insert the depth stop into the auxiliary handle 11.
The knurled surface of the depth stop 10 must face
upward.
Insert the SDS-plus drilling tool to the stop into the
SDS-plus tool holder. Otherwise, the movability of the
SDS-plus drilling tool can lead to incorrect 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 corre-
spond with the desired drilling depth X.
Selecting Drill Chucks and Tools
For hammer drilling and chiselling (chiselling only with
MV 200 accessory), SDS-plus tools are required that
are inserted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic
and plastic as well as for screwdriving and thread cut-
ting, 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.
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 chisel-
ling.

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 mount-
ed (key type drill chuck or keyless chuck, accessories).
Mounting the Key Type Drill Chuck
(see figure C)
Screw the SDS-plus adapter shank 14 into a key type
drill chuck 13. Secure the key type drill chuck 13 with
the securing screw 12. Please observe that the
securing screw has a left-hand thread.
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 auto-
matically 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 13.
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 pro-
tection 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 con-
venient 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 certain 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.
