SECTION 4
NORMAL PROCEDURES

STARTING ENGINE

A minimum battery voltage of 24 volts is not always an
indication that the battery is near full charge or in good
condition. Therefore, if gas generator acceleration in
the initial part of the start is less than normally
observed, return the FUEL CONDITION lever to
CUTOFF and discontinue the start. Recharge the
battery or use an external power unit before attempting
another start.
If the starter accelerates the gas generator rapidly above 20%, suspect
gear train decouple. Do not continue start. Rapid acceleration through
35% N suggests a start on the secondary nozzles. Anticipate a hot
g
start.
After an aborted start for whatever reason, it is essential before the next
start attempt to allow adequate time to drain off unburned fuel. Failure
to drain all residual fuel from the engine could lead to a hot start, a hot
streak leading to hot section damage, or the torching of burning fuel
from engine exhaust on the next successful ignition.
A dry motoring, within starter limitations after confirming that all fuel
drainage has stopped, will ensure that no fuel is trapped before the
next start.
