CHAIN SHARPENING - The pitch of the chain (Fig. 8) is 3/8"
LoPro x .050".
Sharpen the chain using protective gloves and a round file of
ø3/16" (4.8mm).
Always sharpen the cutters with outward strokes only (Fig.9),
observing the values given in Fig. 8.
After sharpening, the cutting links must all have the same width
and length.
WARNING: A sharp chain produces well-defined chips.
When your chain starts to produce sawdust, it is time
to sharpen.
After every 3-4 occasions when you sharpen the cutters, you need
to check the height of the depth gauges and, if necessary, lower
them using the flat file and template optionally supplied, then
round off the front corner. (Fig. 10)
WARNING: Proper adjustment of the depth gauge is as
important as proper sharpening of the chain.
