Blade Sharpening
NOTICE
■
When sharpening blades, grind the same
amount on each blade to maintain balance.

cause excessive vibration which can damage gear

box bearings. Vibration may also cause structural
cracks to cutter.
Always sharpen all blades at the same time to maintain
balance. Follow original sharpening pattern. Do not
sharpen blade to a razor edge, but leave at least a
1/16" blunt edge. Do not sharpen back side of blade.
