If ignition does not occur within 10 seconds
after moving condition lever to LOW IDLE,
initiate engine clearing procedure. If for any
reason a starting attempt is discontinued, the
entire starting sequence must be repeated after
allowing the engine to come to a complete stop
(5 minute minimum).
CONDITION lever (after N1 RPM passes 12%
minimum) - LOW IDLE.
Monitor TGT to avoid a hot start. If there is a
rapid rise in TGT, be prepared to abort the start
before limits are exceeded. During engine start,
the maximum allowable TGT is 1000°C for
five seconds. If this limit is exceeded, use
ABORT START procedure and discontinue
start. Enter the peak temperature and duration
on DA Form 2408-13.
For maximum cooling on the ground, turn the
bleed air valve switches to ENVIRO OFF
