Hold the file at right angles (90°) to the guide bar when
sharpening.
Using the round file and the correct sharpeni
correct breast angle β will result.
The planing tooth lengthes (a) must be equal. Unequal
lengthes may lead to erratic chain run or chain breaking.
Once all sharpening angles are filed your saw chain is
sharp, but it will possibly not cut. There must be always
a depth gaug
e distance (T = distance between depth
gauge and cutting edge).
Use a flat file to file the depth gauge distance.
Be sure to chamfer the leading edge of your depth
limiter with a file. The original shape of the cutting link
must be preserved.
Only remove a little amount of material when
sharpening.
You can also sharpen your saw chain yourself by using our
electric shar
pener KSG 220 (article-no.: 302360).
