MAINTENANCE
Sprocket
• A damaged sprocket will cause
premature damage or wear of saw
chain.
• When the sprocket has worn 0.5
mm (0.020 in.) or more, replace it.
• Check sprocket and the clutch and
clean the bar mount area before
installation of the bar.
• Replace either or both if worn.
Saw Chain Maintenance
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.
