Changing the drill chuck

To remove the keyless chuck (1), clamp a hex key (16) in the keyless chuck (1) and position an open-ended spanner (17) (width across flats: 14 mm) against the spanner flat of the drive spindle.

Place the power tool on a firm surface, e.g. a work bench. Hold the open-ended spanner (17) in place and loosen the keyless chuck (1) by turning the hex key (16) in the rotational direction ➊. A tightly seated keyless chuck can be loosened with a light blow on the long shaft of the hex key (16). Remove the hex key from the keyless chuck and completely unscrew the keyless chuck from the power tool.

The keyed chuck (13) is removed in the same manner as the keyless chuck.
