The chain pitch must match the guide bar. The drive link gauge must match the guide bar groove width. The guide bar and Oilomatic chain are supplied separately. To mount them, first unscrew the collar nut and - if your machine does not have a chain brake - take out the pan head srew and remove the sprocket cover . If you have a Quickstop model, the chain brake must be disengaged before you remove the sprocket cover by pulling the hand guard toward the front handle. Now back off the tensioning nut by turning the tensioning screw counterclockwise until the end of its thread is level with the tensioning nut. Locate the slot of the guide bar over the stud bolt and push it at an angle between the clutch drum of the sprocket and the peg of the tensioning nut until the stud bolt is at the forward end of the slot. To protect yourself from being injured by the sharp cutting edges you should always wear gloves when fitting the saw chain and guide bar or tensioning and checking the chain. 4 3 1 2 3 5 125BA003 LA
