▪ Check the chain tension every time you lubricate the chain. NOTE! A new chain has a
running-in period during which you should check the tension more frequently. Tension the
chain as tightly as possible, but not so tight that you cannot pull it round freely by hand.
▪ Release the sprocket cover lock knob until it snaps open.
▪ Turn the knob anti clockwise to loosen the drive sprocket cover.
▪ Remove all slack from the chain by turning the chain tensioning screw clockwise until the
chain seats snugly against the bar with the drive links in the bar groove.
▪ Turn the screw anti-clockwise for less tension on the chain as needed.
▪ Tighten the sprocket cover by turning the knob clockwise.
Warning: never have more than 3 links removed from a loop of chain. This
could cause damage to the sprocket.
Chain lubrication (also see paragraph 10.2):
▪ Adequate lubrication of the bar and chain during cutting operations is essential to minimize
friction with the guide bar.
▪ Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil
will decrease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and
lead to excessive wear of bar from overheating. Too little oil is evidenced by smoke or bar
discoloration.
