1. A method for open-loop and closed-loop control of a power tool containing a drive, a controller, a sensor, a transmission device and a handle, wherein the handle contains a lever with a signal transmitter, the lever being pivotable relative to the sensor, the method comprising:
sensing a first position and a second position of the signal transmitter by the sensor, wherein a distance between the first position and the second position corresponds to a first determined distance;
determining a difference between a maximum distance of the lever element and the first determined distance;
setting a first rotational speed for the drive when the determined difference between the maximum distance of the lever and the first determined distance corresponds at least to a first predetermined threshold value; and
setting a second rotational speed for the drive when a predetermined period of time has elapsed since the second position of the signal transmitter was reached.
