Care and maintenance
To sharpen the chain proceed as follows:
>
Use protective gloves.
•
Ensure the chain is correctly tensioned.
•
Engage the chain brake to lock the chain on the bar.
•
Use a round file, whose diameter is 1.1 times the cutting tooth
>
depth. Make sure 20% of the file diameter is above the cutter’s
top plate.
A file guide is available from most
>
reputable tool merchants and is
the easiest way to hold the file at
the correct position.
File at an angle perpendicular to
>
the bar, and at an angle of 25° to
the direction of travel (Fig. 43).

File each tooth from the inside towards outside only. File one
>
side of the chain first 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 profile 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. 44).
