Sharpening the Blades
WARNING
Using a grinder in an unsafe manner could
cause serious personal injury or property
damage.
Ensure that the person sharpening the blades
has been adequately trained in how to safely
use a hand-held grinder.
Use an angle grinder to sharpen the angled grinding
surface on the back of the flail blade
Important:
Do not grind the front face of the flail
blade.
While grinding the blade, keep the cutting edge
perfectly horizontal and the angled surface flat to the
ground
(Figure
33).
Use the grinder gently and ensure that the flail does
not get hot; otherwise, the steel will lose its hardness.
Do not sharpen the blades past the wear line that is
indicated by the 5 dots
the flail blades are sharpened equally to maintain the
balance of each rotor.
Keep a new blade as a reference and refer to it when
grinding.
