Selecting Drill Chucks and Tools
mm 23
For hammer drilling and chiselling (chiselling only with
mm 68
MV 200 accessory), SDS-plus tools are required that are in-
mm 13
serted in the SDS-plus drill chuck.
mm 30
For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drills with cylindrical shank). For these tools, a
mm 16
keyless chuck or a key type drill chuck are required.
mm 68
Changing the Key Type Drill Chuck
l/min 450
To work with tools without SDS-plus (e.g., drills with cylindri-
cal shank), a suitable drill chuck must be mounted (key type
pce. 100
drill chuck or keyless chuck, accessories).
pce. 60
pce. 16
Mounting the Key Type Drill Chuck (see figure B)
– Screw the SDS-plus adapter shank 21 into a key type drill
kg 3.6
chuck 20. Secure the key type drill chuck 20 with the se-
kg 2.9 curing screw 19. Please observe that the securing
screw has a left-hand thread.
/II
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 20.
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.
