MAINTENANCE
1.
File each tooth at a 30 degree
angle a specific number of
times, e.g., 4 strokes per tooth.
Work your way around the
blade until all teeth are sharp.
2.
DO NOT file the ‘gullet’ (radius)
of the tooth with the flat file. The
radius must remain. A sharp
corner will lead to a crack and
blade failure.
If an electric grinder is used, use care not to overheat teeth, do not allow
tips/tooth to glow red or turn blue. DO NOT place blade in cooling water.
This will change the temper of the blade and could result in blade failure.
3.
After sharpening
teeth, check each
tooth radius for
evidence of a square
(sharp) corner. Use
the round (rat tail) file
to renew the radius.
