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 B)
Screw the SDS-plus adapter shank 20 into a key
type drill chuck 19. Secure the key type drill
chuck 19 with the securing screw 18. Please ob-
serve 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 19.
