INITIAL ENGINE GROUND RUN
A new engine has been carefully "run-in"
and has passed a rigid final test at the
factory; therefore, no further "break-in" is
necessary. However, it is recommended
that ground operation of the engine be
held to a minimum and engine should be
operated at minimum rpm during the first
10 hours of flight. Engine oil should be
changed and filters cleaned after 10
hours of engine operation.
