Abstract: The disclosure relates to a method for operating a system that includes at least one suction device and at least one hand-held power tool. The method includes establishing a communications link between the suction device and the hand-held power tool by means of at least one suction device communication unit and at least one hand-held power tool communication unit, and transmitting at least one communication signal by means of the communications link from the hand-held power tool, in particular the hand-held power tool communication unit, to the suction device, in particular the suction device communication unit. When the suction device is switched on, at least one start signal is sent to the hand-held power tool, the hand-held power tool being activatable only if the start signal is received by the hand-held power tool.

Abstract: In a method for identifying a deflection or a breakdown of a machine tool, in particular a hand-held machine tool, with an oscillating output movement, in particular a linearly oscillating output movement, at least one physical characteristic of the machine tool, in particular of a motor, a powertrain component, and/or a machining tool of the machine tool, is detected continuously or periodically by means of a detection unit. The method further includes detecting a deflection or a breakdown of the machine tool with an analysis unit on the basis of at least two values, which are identified at different times, of the characteristic of the machine tool, wherein each of the at least two values of the characteristic are associated with at least one respective substantially identical value of a discrete position characteristic of the oscillating output movement, in particular the linearly oscillating output movement, of the machine tool.

Abstract: A removable dust collection apparatus, in particular a removable dust collection container, for a hand-held power tool, includes at least one basic structure, which has at least one frame for receiving a form-variable collection bag or itself delimits a collection volume at least in part. The basic structure has at least one connecting piece for connection to a blow-out connector of the hand-held power tool, the connecting piece configuring the basic structure to be removably arranged on the hand-held power tool. The dust collection apparatus further includes at least one communication unit, which is in particular wireless, for exchanging in particular electronic data with at least one external unit, in particular the hand-held power tool or a mobile communication device.
