Section 12.5
Operating Conditions

The operating limits for the Series 60 diesel engine are listed in Table "Series 60 Engine Lubrication System Parameters" , and listed in Table "Series 60 Engine Air System, Fuel System, and Cooling System Parameters" . Any variations from the conditions as listed may indicate an abnormal situation in need of correction. Be sure that the readings represent true values and the instruments are accurate before attempting to make corrections to the engine. This data represents rated conditions. Actual data may be influenced by environmental conditions.‪
