Abstract
A hand-operated rotary power tool and a method of operating the tool is disclosed. The tool has an electric motor for driving a rotary tool, a sensor device for detecting a blockade of the tool and a triggering device, which, in response to a blockade detected by the sensor device, reverses a direction of rotation of the electric motor prior to the blockade for a predetermined duration and immediately following induces the electric motor to again rotate in the direction of rotation.
