ABSTRACT:
The invention relates to an apparatus in an engine-driven machine having a tool carrier for a rotary tool and having a splinter shield cover (20) for the tool, which cover houses a section of the tool and has a through-running fixture hole (27) for the cover in a bearing side wall. What distinguishes the invention is that the apparatus comprises clamping devices (79) on the inside of the side wall, that the side wall of the cover is clamped between the clamping devices and the tool carrier (5), and that the first and second locking devices (79, 78) are arranged on the one side of the side wall up to the fixture hole, which locking devices, in mutual interaction and under the influence of the clamping force, prevent the cover from rotating about the center of rotation (31) of the tool, due to normally occurring stresses whilst the machine is in use, when the side walls of the cover are clamped between the clamping devices and the tool carrier, but which allow rotation of the cover with manual force applied to the cover for graduated, indexed adjustment of the cover into desired, indexed rotational positions relative to the tool carrier, the clamping force being herein surmounted.
