This chapter of the Operator Manual contains information about
the general engine specification as well as a description of
cooling system, fuel system, lubrication system, electric system
and the propeller gearbox.
The system description refers only to the engine and not to a

manufacturers Operators Manual is therefore definitive in terms
of the operation of the engine, as it contains all the aircraft
