round file and holder (available
separately). Do all of your filing at
the middle position of the guide bar.

of the tooth. Do not let the file dip or
rock.
5. Keep a correct sharpening angle of
30° between the file and the saw
chain (see Fig. 33 & 34). Always use
a file holder (available separately)
when sharpening saw chains by
hand. File holders have markings for
the sharpening angle.

perform a stroke towards the front
corner of the tooth. Lift the file away
from the steel on each return stroke.
7. Make a few firm strokes on every
tooth. File all left-hand cutters in
one direction. Then move to the
other side and file the right-hand
cutters in the opposite direction.
Occasionally remove filings from the
file with a wire brush (Fig. 35).
