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.
