Clean the guide bar mount area before installing the guide bar.
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 when you install new
chain. Replace it if worn.
Some tree sap and resins are corrosive. Thoroughly wash the guide
bar and sprocket areas after each use, then coat metal parts with light
oil.

cooling.
