Fuel control (2) is equipped with an ad-
justment that is used to set the airbleed
tory if bleed band closure is not within
specified N1 speed. If N1 speed for bleed
band closure is above that specified, an

tion will result until bleed band closes. If
bleed band does not close at all or opens

loss of maximum power.
Start engine and operate at ground
idle to allow temperatures to stabilize.
