Abstract: The invention described here entails a work device (such as an abrasive cutting-off machine) that can be comfortably guided in a work position and is stable in a turned-off position without components relative to safety being exposed to increased wear. In particular, the work device has a foot unit having at least one rolling means and at least one support. The foot unit makes it possible to guide the abrasive cutting-off machine on the at least one rolling means in the work position and to set it on the support in the turned-off position.

Abstract: This invention entails a guide device, especially for use with abrasive cutting-off machines, which has at least one rolling means for rolling the guide device substantially by the body power of a user. The guide device has at least one handle arranged opposite the rolling means for transferring a force exerted by the arms of the user onto the handle. The device is characterized by a pushing element for transferring a force exerted by another body part of the user, in particular the thigh, onto the guide device.

Abstract: The invention entails an actuatable tool, such as a chain saw, with at least one handle for manually manipulating the tool by one hand of a user. The tool includes at least one device in at least one area of the at least one handle. The device is suitable and adapted for radiating energy in the form of electromagnetic radiation in the microwave range so that a warming of the user's hand can be brought about.

Abstract: The invention relates to a holding device for holding a tool, especially an abrasive cutting-off machine, on a guide device, especially on a guiding carriage. The invention may be characterized by holding device which comprises at least one overlapping element via a receptacle, which overlapping element cooperates with at least one holding element on a tool in such a manner that the tool can be suspended by the holding element or elements on the overlapping elements or elements and be transferred by rotation about an axis about a position of use into a held position.

Abstract: In order to develop further a portable motor or engine-driven cutting-off machine with a housing (100) and an arm (12) connected thereto, on which a parting-off tool (22) is detachably secured, which can be driven with the aid of a traction means gearing (13, 14, 28) with a power transmission shaft (14) disposed on the arm (12) in such a way that, by means of simple constructional modifications, the rigidity between housing and arm is enhanced and their disadvantageous vibration behavior during cutting operations is improved, it is proposed that the arm (12) and the housing (100) or a housing half (11) be fabricated in a one-piece construction.
