Assembly
 Before any work on the machine itself, pull the mains
plug.
Auxiliary Handle
 Operate your machine only with the auxiliary handle
11.
Changing the position of 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 counter-
clockwise 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 in-
sert the depth stop into the auxiliary handle 11.
– The knurled surface of the depth stop 10 must face down-
ward.
– 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
drilling depth.
– Pull out the depth stop until the distance between the tip of
the drill bit and the tip of the depth stop corresponds 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 in-
serted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drill bits 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 cylindri-
cal shank), a suitable drill chuck must be mounted (key type
drill chuck or keyless chuck, accessories).
Mounting the Key Type Drill Chuck (see figure C)
– Screw the SDS-plus adapter shank 15 into a key type drill
chuck 14. Secure the key type drill chuck 14 with the se-
curing screw 13. 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 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 14.
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 im-
mediately. We recommend having 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.
