WARNING: Operation of this propeller over maximum RPM
is strictly prohibited and may result in a catastrophic
structural failure of the propeller system. Any type of
structural failure may result in death or severe bodily
injury. Refer to your propeller data sheet for Maximum
RPM.
Be sure to limit engine power settings when performing ground run-
up. Engine and propeller manufacturers do NOT recommend high
engine power settings on the ground because it can result in
excessive engine temperatures and propeller blade foreign object
damage.
