To sharpen the cutting teeth
Use a round file and a file gauge to sharpen the cutting
Saw chain filing and saw chain combinations
teeth. See
on page 26 for information on the recommended
dimension of the file and gauge for the saw chain
installed on your product.
1. Make sure that the saw chain is correctly tensioned.
A slack chain will move sideways, making it more
difficult to sharpen correctly.
2. File all teeth on one side first. File the cutting teeth
from the inside face and reduce the pressure on the
return stroke.
3. Turn the product over and file the teeth on the other
side.
