Abstract

A hand-held working tool has a drive motor and a grip connected at a distance to the drive motor. Operating elements, including a throttle lever, a choke actuator, and a short-circuiting switch, are connected to the grip for controlling the drive motor. A transmission device, including a Bowden cable arrangement with a sleeve and a cable enclosed by the sleeve, is provided for connecting the operating elements to the drive motor. The transmission device has an inner tube inserted into the Bowden cable arrangement wherein the inner tube is positioned between the sleeve and the cable so as to be longitudinally displaceable relative to the sleeve and the cable.
