CHECK CHAIN SHARPNESS

A sharp chain makes wood chips. A dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARPENING in the SERVICE AND ADJUSTMENTS section.

CHECK GUIDE BAR

Conditions which require guide bar main- tenance:

SSaw cuts to one side or at an angle. S Saw has to be forced through the cut. S Inadequate supply of oil to the bar and

chain.

Check the condition of the guide bar each time the chain is sharpened. A worn guide bar will damage the chain and make cut- ting difficult.

After each use, with unit disconnected from power source, clean all sawdust from the guide bar and sprocket hole.

To maintain guide bar:

S Disconnect the chain saw from the pow- er source.

S Loosen and remove bar clamp nuts. Remove bar and chain from saw.

S Clean the oil holes and bar groove after each 5 hours of operation.
