> A le guide is available from most
reputable tool merchants and is
the easiest way to hold the le at
the correct position.
> File at an angle perpendicular to
the bar, and at an angle of 25° to
the direction of travel (Fig. 51).
> File each tooth from the inside
towards outside only. File one
side of the chain rst then 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 prole is restored.
> Use a depth gauge measuring instrument to check the height of
the depth gauge. Depth gauge measuring jigs are available from
most reputable tool merchants (Fig. 52).
