    摘要： The present disclosure relates to a chain saw of a wood handling device and to controlling the guide bar in it. The guide bar is attached to a turning frame rotatably arranged to a frame of the chain saw through a fastening arrangement. The fastening arrangement of the guide bar and the turning frame are joined by at least one guide for controlling the guide bar during movement along its longitudinal axis. The guide includes opposite slide guides with opposite sliding and mating surfaces that form a form-locking joint joining the fastening arrangement and turning frame together. This type of separate slide guide arranged in the chain saw is movable in at least one direction differing from the direction of travel allowed by the guide, which makes it possible to modify clearance between the sliding surface and mating surface.
