Changing the tool (see figure A)

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.

Open the keyless chuck (2) by turning it in the direction of rotation ➊ until the tool can be inserted. Insert the tool.

Firmly tighten the keyless chuck (2) by turning it by hand in the direction of rotation ➋. This will automatically lock the drill chuck.
