Engines rated for constant speed use are allowed to complete a starting sequence, an operation at a single constant speed, and a shutdown sequence. Each of these operations should occur only once for each period of engine operation. The starting sequence and shutdown sequence can include a short period of operation at the low idle speed in order to warm up and cool down the engine or driven equipment. The emissions type approval is not valid for operation of a constant speed engine in a manner different from the manner described above.
Note: If equipped, set the "IDLE/RATED SPEED" switch to the IDLE position before starting the engine.Normal Starting Procedure

Refer to the Operation and Maintenance Manual, "Diagnostic Flash Code Retrieval" (Operation Section) for more information.
