(14) Move the No. 1 thrust lever forward from the idle position until the API shows a value of 80.00 degrees.
NOTE: Move the thrust levers forward smoothly from the idle
____ position to prevent hysteresis during the thrust lever adjustment. If more than 80.00 degrees occurs, put the thrust lever back to the idle position and do this step again.
