Zusammenfassung:The invention relates to an impact device and a method of dismounting an impact device from a breaking device. The impact device (12) comprises a bush (16) inside which is a percussion piston (21). The impact device is arranged inside an impact device space formed in a frame (20) of a breaking device (15). The percussion piston is provided with a pull shoulder (33) allowing a dismounting force (FB) in a return direction (B) to be transmitted from the percussion piston to the bush. Thus, the bush is extracted from the frame by means of the percussion piston.
