Abstract
The invention relates to a motor-driven operating device that comprises a guide handle. Two sensor elements are provided on the guide handle and in two handle areas for detecting the hands of an operator. An ignition device of the motor is controlled by means of a security control device in such a way that the speed can only be increased beyond a security speed when the guide handle is held with both hands, whereby said security control device evaluates the sensor signals. The motor speed is limited to the security speed when the two sensor signals are missing.
