Abstract: A hand-held power tool for sanding or polishing a working surface of a workpiece features a backing pad supported in respect to a housing in a manner freely rotatable about a longitudinal axis extending perpendicular to an extension plane of the backing pad. The housing or backing pad includes first magnetic elements spaced apart from each other in a direction extending parallel to the extension plane, and includes a second magnetic element located in a space between the first magnetic elements in such a manner that the second magnetic element is held at a distance to the first magnetic elements by a magnetic force when a motor of the power tool is running and the power tool is in an idle state, thereby limiting the movement of the backing pad to an orbital movement.

Abstract: A hand-held/hand-guided random orbital polishing/sanding power tool has a static body and a motor for driving an eccentric element with a rotational movement about a first rotational axis, and a plate-like backing pad rotatably connected to the eccentric element about a second rotational axis. The first/second axes extend parallel to and spaced apart from one another. Part of an external circumferential surface of the eccentric element has a rotational symmetry re the first axis to form a rotationally symmetric part. The tool has a first bearing between the rotationally symmetric part and the static body so the eccentric element is rotatably guided re the static body about the first axis, and also having a mechanical gear arrangement with two meshing gear wheels arranged between the motor's drive shaft and the eccentric element, and one meshing gear wheel attached to the eccentric element for transmitting torque thereto.

Abstract: The invention refers to a remote control (50) for controlling an operation status of a suction device (2). The remote control (50) comprises a radio transmitter (88) for transmitting a first radio signal (30) to the suction device (2) for turning on or off the suction device (2). It is suggested that the remote control (50) further comprises a radio receiver (90) for receiving a second radio signal (54) from a communication device (32) located at a second end (16) of a suction hose (12), which is connected to a suction opening (10) of the suction device (2) with its first end (14) and to an air outlet (18) of a hand-held electric or pneumatic power tool (20) with its opposite second end (16). The communication device (32) detects a current operation status of the hand-held electric or pneumatic power tool (20) and emits the second radio signal (54) indicative of the current operation status of the hand-held electric or pneumatic power tool (20).

Abstract: The invention refers to a hand-held and hand-guided motor driven polishing or sanding tool (2). The tool (2) has a tool housing (4) and a motor (6; 62) located therein.
