Sharpen the chain before it gets dull

LEARN HOW TO RECOGNIZE THE SIGNALS of a chain beginning to be dull. If you fi le the chain before it gets dull it only needs a few light strokes with the fi le on each cutting tooth. There is practically no wear and tear on the chain and bar when the chain is sharp. If the chain has been damaged or unevenly fi led it can start pulling sideways. This can also occur when the guide bar is so worn that the chain touches the bottom of the bar groove. Check that the cut goes straight by watching the distance between the guide bar and the fresh-cut surface when the saw is pulled back. If the chain is pulling sideways, the guide bar gets worn unevenly and even a new chain will then steer in the wrong direction. The guide bar can be fi led with a UFK edge file.
