Sharpening cutting teeth
To sharpen cutting teeth you will need a round file and a
file gauge.
• Check that the chain is correctly tensioned. A slack
chain will move sideways, making it more difficult to
sharpen correctly.
• Always file cutting teeth from the inside face outwards.
Reduce the pressure on the return stroke. File all the
teeth on one side of the bar first. Then turn the saw
over and file the remaining teeth from the other side.
