Certification
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 1. Otherwise, the mov-
ability 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
correspond 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, 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).
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 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 13.
