File each tooth from the inside towards outside only. File one >
side of the chain rst than turn the saw around and repeat the
process.
Sharpen each tooth equally by using the same number of >
strokes.
Keep all cutter lengths equal. Check the safety depth gauge >
height every 5 sharpenings. If the depth gauges are also trimmed
it is essential that the original prole is restored.
