摘要： A self-propelled working device is provided with a housing and a pivot bearing arranged on the housing. At least one operating element is arranged on the housing. At least one lid is pivotably supported on the housing and is provided with a bearing section interacting with the pivot bearing. The at least one lid has a closed position and covers in the closed position the operating element. The lid has a first part and a second part connected to the first part. The bearing section is formed on the first part of the lid. The second part of the lid covers the operating element. When a constructively predetermined pulling force is applied to the second part, the second part detaches from the first part.

摘要： A power tool is provided with a drive motor and a drive shaft connected to the drive motor so as to be driven in rotation about an axis of rotation. A disk is fixedly secured to the drive shaft so as to rotate with the drive shaft. At least one knife is arranged on a face of the disk that in operation of the power tool is facing the ground. The at least one knife is fixedly connected to the disk and a driving torque for rotatingly driving the at least one knife about the axis of rotation is transmitted from the disk onto the at least one knife. A spacing of a radial outer edge of the at least one knife relative to the axis of rotation is smaller than a radius of the disk.

摘要： The invention relates to a method for operating a self-propelled lawnmower, which is moved on a surface (20). The surface (20) is surrounded by a border delimitation wire (21) on which electrical signals (16, 116) are transmitted. The transmitted signal (16) is received by at least one receiving coil (17, 18) in the lawnmower (2) and induces a reception signal (EI), which is evaluated in an evaluation unit (19). The evaluation unit (19) emits an output signal to a control unit (13), on the basis of which the control unit (13) controls the direction of travel of the lawnmower (2). In order to guarantee a safe operation of the lawnmower even in range of electromagnetic interference fields, the invention provides that the electrical signal (16, 116) is transmitted with a predetermined pattern (M). The evaluation unit (19) of the lawnmower (2) processes the reception signal (EI) as a pattern, wherein the pattern (M′) of the reception signal (EI) is compared to a predetermined reference pattern (RM). Information regarding the location of the lawnmower (2) inside or outside the border delimitation wire (21) is obtained from the comparison result. The control unit (13) will determine the direction of travel of the implement on the basis of this information.

摘要： A fastening element for fixation of a wheel on a wheel axle has a first section and a second section that are movable relative to each other and are separated from each other by a plane of separation. The first section has devices for fixation on the wheel axle. The second section has a wheel axle cover. A substantially closed outer wall that is divided by the plane of separation is provided on the fastening element.

摘要： A self-propelled working device has a housing and an operating element arranged on the housing. A pivot bearing is arranged on the housing. A lid is pivotably arranged on the housing so as to pivot about a pivot axis of the lid, wherein the lid has a closed state in which the lid covers the operating element and an open state enabling access to the operating element. The lid has a bearing section interacting with the pivot bearing, wherein the bearing section and the pivot bearing define the pivot axis of the lid. A first Hall sensor is arranged in the housing and monitors a pivot position of the lid. A first magnet is arranged on the bearing section of the lid. The first magnet rotates when the lid pivots about the pivot axis and the magnetic field of the first magnet is detected by the first Hall sensor.
