6.3 Sharpening the blades

Any burrs may be removed and the blade smoothed only in the grinding area (Pic-
ture)! Break outs or deep cracks cannot be ground away; in such cases the blades
must be replaced�
Tools required:
en
1� Clamping device (e�g�, vise) with jaw protection
2� Grinder (e�g� angle grinder or belt grinder) with abrasive having a grain size of
80. A diamond file is adequate for small burrs.
Procedure:
1� Clamp the blade securely into the clamping device so that it cannot move,
leaving the grinding area exposed (Picture P�)�
2� Carefully de-burr the grinding area with the grinding machine (Picture P�)�
