3.13.3 DEFECTIVE PROPELLER RPM REGULATING SYSTEM
CAUTION
The POWER lever should be moved slowly, in order to avoid
over-speeding and excessively rapid RPM changes. The light
wooden propeller blades produce more rapid RPM changes
than metal blades.
WARNING
In case of a malfunction of the engine control unit, it is
possible that the propeller blades will remain in the position
of highest pitch. In this case the reduced engine performance
should be taken into consideration.
