This is a summary of the engine start procedure:
* Follow safety procedures and airplane and engine limitations
* Set the ignition select switch to IGN L or IGN R
* Put the engine start switch to the GRD position
* Look for start valve open indication
* Monitor N2
* Make sure oil pressure increases
* Speak with ground personnel to make sure N1 begins to turn counterclockwise
* Move the engine start lever to the idle position (forward) at a minimum of 25 percent N2
* Make sure fuel flow is in limits
* Make sure EGT increases
* Monitor EGT and N2 increase until starter cutout at 55 percent N2
* Make sure engine start switch goes back to the OFF position at 55 percent N2
* Monitor all engine parameters as engine speed increases to idle.
