A cutting and splitting machine comprising: a machine housing , a splitting section provided with a splitting knife for splitting pieces of sawlog into chopped wood and arranged in the housing, a cutting section arranged in the housing and further comprising a circular saw for cutting sawlog into pieces and a circular saw guide mechanism which guides the circular saw substantially horizontally from the initial position (A) of the circular saw to the final position (B), i.e. the transport position of the circular saw, and back again, characterised in that the housing has an attachment piece with a rectangular through hole through which the circular saw protrudes at least partially from the housing in the initial position (A) of the circular saw, and that the cutting and splitting machine further comprises a folding cover having a rectangular cross-section in a plane perpendicular to the direction of guidance of the circular saw, so as to substantially geometrically fit the rectangular through hole in the attachment piece and to receive a part of the circular saw which protrudes from the housing in the initial position of the circular saw, wherein the folding cover is connected to the machine housing by two hinges which are linearly guided in folding cover guides arranged on the machine housing so that the folding cover can be linearly moved from the transport position (C) of the folding cover, in which the folding cover is positioned adjacent to the machine housing, in the direction of travel of the circular saw, to a position in which it is distant from the machine housing and can then be pivoted about its hinges to the operating position (D) of the folding cover, in which it can receive the circular saw in its initial position (A), the folding cover being provided with first fastening means for fixing the folding cover in its transport position (C) and second fastening means for fixing the folding cover in its operating position (D). a machine housing , a splitting section provided with a splitting knife for splitting pieces of sawlog into chopped wood and arranged in the housing, a cutting section arranged in the housing and further comprising a circular saw for cutting sawlog into pieces and a circular saw guide mechanism which guides the circular saw substantially horizontally from the initial position (A) of the circular saw to the final position (B), i.e. the transport position of the circular saw, and back again, characterised in that the housing has an attachment piece with a rectangular through hole through which the circular saw protrudes at least partially from the housing in the initial position (A) of the circular saw, and that the cutting and splitting machine further comprises a folding cover having a rectangular cross-section in a plane perpendicular to the direction of guidance of the circular saw, so as to substantially geometrically fit the rectangular through hole in the attachment piece and to receive a part of the circular saw which protrudes from the housing in the initial position of the circular saw, wherein the folding cover is connected to the machine housing by two hinges which are linearly guided in folding cover guides arranged on the machine housing so that the folding cover can be linearly moved from the transport position (C) of the folding cover, in which the folding cover is positioned adjacent to the machine housing, in the direction of travel of the circular saw, to a position in which it is distant from the machine housing and can then be pivoted about its hinges to the operating position (D) of the folding cover, in which it can receive the circular saw in its initial position (A), the folding cover being provided with first fastening means for fixing the folding cover in its transport position (C) and second fastening means for fixing the folding cover in its operating position (D). <EOS>
