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.
