Abstract
A method for controlling or regulating a hand-held power tool, in particular a screwdriver, preferably a rotary impact screwdriver.

A method for controlling or regulating a hand-held power tool, the method comprising the following steps:
- applying a first torque to a screw in a first direction of rotation;
- and
- applying a second torque to the screw in a second direction of rotation opposite to the first direction of rotation,
- wherein a first target torque is provided for limiting an application of the first torque to the screw in the first direction of rotation,
- wherein a second target torque is provided for limiting an application of the second torque to the screw in the second direction of rotation, wherein the second target torque is adjustable as a function of the first torque in the first direction of rotation.
