# Changing the drill chuck

## Inserting/removing the keyed chuck

You must use a suitable drill chuck (keyed or keyless chuck, accessories) to work with tools that do not have SDS-plus (e.g. cylindrical shank drill bits).

##

- Screw the SDS-plus shank (20) into a keyed chuck (19). Secure the keyed chuck (19) using the securing screw (18). Note that the securing screw has a left-hand thread.

##

- Clean and lightly grease the insertion end of the shank.
- Insert the keyed chuck with the adapter shank into the tool holder with a turning motion until it automatically locks.
- Check that it is locked by pulling the keyed chuck.

##

- Push the locking sleeve (4) back and remove the keyed chuck (19).
