SRM-225

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.
