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.

TROUBLESHOOTING
