3. To sharpen the blades yourself, clamp the blade
securely in a vise.
Use a large mill file and file along the original bevel
until sharp.
4. To check the blade for balance, place a small rod
through the center hole. If the blade is not
balanced, file the heavy side of the blade until
balance is achieved.
5. Pass the spline boss through the blade and 2 cup
washers, and tighten the bolt.
NOTE :
• Make sure that the cup washer is not
flattened out or worn; this will cause blade
