The Start the Engine (Normal Operation) and Engine Shutdown (Normal) procedures are the usual procedures to operate the engine.
C.
The procedure to motor the engine is when you turn the engine with the starter but you do not supply the ignition. The Dry-Motor procedure supplies fuel to the fuel pump as a lubricant, but not to the combustion chamber. The Wet-Motor procedure supplies fuel to the fuel pump and lets the fuel go into the combustion chamber. Thus, you must only use the Wet-Motor procedure when it is necessary.
D.
The Power Plant Operation (Cold Weather) is the engine operation procedure for the engines in the conditions of snow, ice and temperatures less than 32°F (0°C).
E.
The Prime the Engine Oil and Fuel System procedure adds engine oil to the engine oil system or fuel to the fuel system when the oil compartments and fuel system components are drained.
