Edger Blade Replacement - Echo PAS-225 Operator's Manual

MAINTENANCE
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 cool-
ing 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.
