Setting The Saw Chain

Important points for proper maintenance of saw chain:

• Keep the cutters sharp at all times.

• Keep the left and the right cutters properly aligned.

• Note that blunt or irregular cutters will result in poor cutting

performance, increased vibration of chains and premature

breakage of the saw chain.

• Drive link serves to remove sawdust from the groove of the

guide bar. Keep the lower edge of the drive link sharp where

indicated.
