The drill spindle is locked when the on/off switch (10) is not pressed. This makes it possible to change the application tool in the drill chuck quickly, conveniently and easily.

Firmly tighten the sleeve of the keyless chuck (2) by turning it by hand in the rotational direction ➋ until it stops clicking. This will automatically lock the drill chuck.
