 A. General
 (1)  
This procedure contains the instructions necessary to operate the engine during the permitted conditions. You can use this procedure to examine the operation of the engine or the related systems when the engine operation is necessary.

 (2)  
During cold weather, use the Power Plant Operation (Cold Weather) procedure to operate the engine.

 (3)  
It is important to have a clean engine compartment because the large quantity of mass airflow can pull unwanted material into the engine.

 (a)  
You must fully clean and examine the area after you are done with the work.

 (b)  
Make sure there is no dirt, oil, or grease in the inlet area.

 (c)  
Remove all parts which are not used, for example, nuts, washers, and pieces of lockwire.

 

 (4)  
To prevent corrosion in the compressor stages and damage to the fan, you are recommended to install the applicable covers on the engine inlet and exhaust when it is possible.

 (5)  
When the temperature is less than 0°C (32°F) or there is sufficient wind to turn the engine, it is important to immediately install the covers on the engine.

 (6)  
You must monitor the drain mast during the start for signs of leakage.

 (7)  
You must make a record of the engine indication on the PERF page with the vertical scale displays during the transient operation and the digital displays during the continuous operation.
