    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.

    摘要： The present disclosure relates to an arrangement for transferring fluid to a guide bar in a chain saw. A channel can extend from a chain saw body to the fastening arrangement of the guide bar. The channel can include a cavity through the entire channel, a first end of the cavity being connected to a feed channel provided in the chain saw body and a second end thereof to a counter channel provided in the fastening arrangement. The counter channel, in turn, is arranged to extend to the guide bar. The channel is thus arranged to guide fluid flowing in the feed channel provided in the chain saw body through the channel and further through the counter channel provided in the fastening arrangement to the guide bar.
