SUBSTANCE: invention relates to a saw chain of a device for handling timber and to control of a guide tire available in it. Guide bar is made with possibility of attachment to the rotary frame, which is installed with possibility of rotation on the frame of the chain saw, by means of the fastening structure. Fixing structure of the guide bar and the rotary frame are connected by means of at least one guide in order to control the guide bar during movement in the direction of its longitudinal axis. Guide comprises opposite sliding guides with opposite sliding surfaces and conjugated surfaces, which form connection by engagement of moulds, connecting fastening structure and rotary frame to each other. At least one of them is formed by separate facility arranged with the possibility of location in chain saw. Such separate sliding guide arranged with the possibility of being located in the chain saw can move in at least one direction different from the direction of movement of the allowable guide.
