Flail Axe Blade Bolt Inspection
Inspect Blade Bolts daily for wear or damage as follows:
Inspect the Blade Bolt daily for abnormal wear. REPLACE ALL BLADE BOLTS on the
carrier IMMEDIATELY if any bolts have:
• Visible cracks or
• If the blade bolt is worn or any recessed area is visible on the bolt, or
• If Blade Bolt has gouges or chipped areas. or
• If Bushing fits loose in the Rotor Shaft.
Failure to replace abnormally worn bolts or bushings may lead to catastrophic failure of the blades and
ejection of the broken part which may cause serious bodily injury or death.
Always replace Blade Bolts with new bolts and new bushings whenever replacing the Blades. To tighten bolts
and nuts, first apply thread lock to nut. Make sure to tighten bolts and nuts just enough to allow the blades to
swing freely, and not bend the cuttershaft lugs. If cuttershaft lugs are bent together because of over tightening
the blades will not swing freely. OPS-U-0043
