An impact machine (100; 200; 700) comprising: - a housing (105; 205; 705) - a hammering element (110; 210; 710) arranged inside said housing (105; 205; 705), said hammering element (110; 210; 710) being displaceable between a first hammering element position and a second hammering element position, - an impact receiving element (130; 230) attached to said housing (105; 205; 705), - actuating means (115; 215) arranged to cause said hammering element (110; 210, 710) to perform a hammering operation on said impact receiving element (130; 230), - a vibration reduction arrangement attached to said housing, which comprises: - at least one counterweight distributed around said hammering element and being displaceable in a first axial direction between a respective first counterweight position and a respective second counterweight position in response to the hammering action of said hammering element, - a respective first motion reversing mechanism for each one of said at least one counterweight, each respective first motion reversion mechanism comprising a first spring-action arrangement (760, 760') being arranged to reverse the direction of motion of a respective one of said at least one counterweight, wherein each of said respective first motion reversing mechanism further comprises a first end surface (S END1) attached to said housing and arranged adjacent to said respective first counterweight position, characterized in that - each one of said at least one counterweight is arrangeable at a position located between said respective first counterweight position and said respective second counterweight position from which position each one of said at least one counterweight is moveable a first distance (D 1) extending in said first axial direction without actuating said first spring-action arrangement (760, 760'); and - the spring action arrangement of said respective first motion reversing mechanism is arranged inside said respective one of said at least one counterweight, and - each one of said at least one counterweight comprises a first projecting member (780, 790), which projecting member comprises an engaging surface, which engaging surface is connected to said respective spring action arrangement (760, 760') and arranged between said respective spring action arrangement and said first end surface (S END1) in said first axial direction wherein when any of said at least one counter weight is arranged in said respective first counterweight position: - said engagement surface and said first end surface (S END1) are pressed against each other, and - said at least one spring-action arrangement (760, 760') is actuated. - a housing (105; 205; 705) - a hammering element (110; 210; 710) arranged inside said housing (105; 205; 705), said hammering element (110; 210; 710) being displaceable between a first hammering element position and a second hammering element position, - an impact receiving element (130; 230) attached to said housing (105; 205; 705), - actuating means (115; 215) arranged to cause said hammering element (110; 210, 710) to perform a hammering operation on said impact receiving element (130; 230), - a vibration reduction arrangement attached to said housing, - at least one counterweight distributed around said hammering element and being displaceable in a first axial direction between a respective first counterweight position and a respective second counterweight position in response to the hammering action of said hammering element, - a respective first motion reversing mechanism for each one of said at least one counterweight, each respective first motion reversion mechanism comprising a first spring-action arrangement (760, 760') being arranged to reverse the direction of motion of a respective one of said at least one counterweight, wherein each of said respective first motion reversing mechanism further comprises a first end surface (S END1) attached to said housing and arranged adjacent to said respective first counterweight position, characterized in that - each one of said at least one counterweight is arrangeable at a position located between said respective first counterweight position and said respective second counterweight position from which position each one of said at least one counterweight is moveable a first distance (D 1) extending in said first axial direction without actuating said first spring-action arrangement (760, 760'); and - the spring action arrangement of said respective first motion reversing mechanism is arranged inside said respective one of said at least one counterweight, and - each one of said at least one counterweight comprises a first projecting member (780, 790), which projecting member comprises an engaging surface, which engaging surface is connected to said respective spring action arrangement (760, 760') and arranged between said respective spring action arrangement and said first end surface (S END1) in said first axial direction wherein - said engagement surface and said first end surface (S END1) are pressed against each other, and - said at least one spring-action arrangement (760, 760') is actuated.
