Flail/Tooth Inspection & Replacement; Rotor Vibration - McConnel 1300 Operation Manual

Flail/Tooth Inspection & Replacement
It is important that the flails/cutting teeth are inspected for signs of excessive wear or
damage before using the machine and on a regular basis during the working day.
Any rotor components that show signs of excessive wear or damage must be replaced
immediately as total failure of these items can lead to broken parts being ejected at high
velocity; this could cause catastrophic damage to the machine and/or serious bodily injury
or even death. Always fit genuine McConnel replacement parts on these machines.
Flails must be replaced immediately if they show any of the following signs;
 Bent or deformed from their original shape.
 Bolt hole worn.
 Cracks are visible.
 Deep gouges in the blade surface.
 Leading edge is excessively worn or damaged.

Rotor Vibration

If vibration of the rotor is experienced the machine should be stopped immediately – this is
often a sign that a flail is either missing or severely damaged, if this is the case do not use
the machine until the problem has been rectified. If vibration continues, or occurs for no
apparent reason, the rotor must be checked and if necessary rebalanced before using the
machine again. Contact your local dealer for further advice or assistance on this subject.
