Abstract: An impact device and a method of dismounting an impact device from a breaking device is disclosed. The impact device includes a bush having a percussion piston disposed therein. The impact device is arranged inside an impact device space formed in a frame of a breaking device. The percussion piston is provided with a pull shoulder allowing a dismounting force in a return direction to be transmitted from the percussion piston to the bush. Thus, the bush is extracted from the frame by means of the percussion piston.
