TM 1-1510-225-10 8A-10 * 8A-22.  FIRST ENGINE START (BATTERY START). Starting procedures are identical for both engines except  the  second  engine  generator  is  kept  off  line after  the  second  engine  start  to  allow  performing  the current  limiters  check.    When  making  a  battery  start, the right engine should be started first.  A crewmember should  monitor  the  outside  observer  throughout  the engine start. 1.   BATT switch – ON (22 volts minimum). 2.   Exterior LIGHTS – As required. 3.   Propeller area – Clear. 4.   Engine – Start. CAUTION If ignition does not occur within 10 seconds   after   moving    the    condition lever to LOW IDLE initiate Engine Clearing procedure,   Paragraph   8A-25.      If   for   any reason the starting attempt is discontinued, the  entire  starting  sequence must be repeated after allowing the engine to   come   to   a   complete   stop   (1   minute minimum). a.  IGNITION  AND  ENGINE  START  switch  – ON. IGN ON annunciator should illuminate and associated  FUEL PRESS  annunciator extinguished. b.  CONDITION lever (after N₁ stabilizes at or above   12%   for   5   seconds   minimum)   – LOW IDLE. CAUTION Monitor ITT to avoid a hot start.  If there is a rapid rise in ITT, be prepared to abort the start  before  limits  are  exceeded.    During starting, the maximum allowable ITT is I000 ºC for 5 seconds.  If this limit is exceeded, use  Abort  Start  procedure,  Paragraph  8A- 24, and discontinue start.  Record the peak temperature   and   duration   on   DA   Form 2408-13-1. c.   ITT   and   N₁   –   Monitor.      ITT   1000   °C maximum.  N₁ minimum 58%. d.  Oil pressure – Check (60 psi minimum). e.  IGNITION  AND  ENGINE  START  switch  – OFF after 50% N₁. 5.   Engine and systems instruments – Check. 6.   CONDITION lever – HIGH IDLE.  Monitor ITT as the condition lever is advanced. NOTE Ensure N₁ is at high idle before turning on generator. 7.   GEN switch – RESET, then ON. a.  BATTERY CHG annunciator – Monitor. NOTE The   ICE   VANE   switch   should   be   set   to EXTEND    for    all    ground    operations    to minimize  ingestion  of  ground  debris.    Set switch   to   RETRACT   to   maintain   engine temperatures within limits. * 8A-23.  SECOND     ENGINE     START     (BATTERY START). 1.   First  engine  generator  load  –  50%  or  less  – GEN switch OFF. 2.   Propeller area – Clear. 3.   Engine – Start. a.  IGNITION  AND  ENGINE  START  switch  – ON.    IGN  ON  light  should  illuminate  and FUEL PRESS light should extinguish. CAUTION If ignition does not occur within 10 seconds   after   moving    the    condition lever to LOW IDLE, initiate Engine Clearing procedure,   Paragraph   8A-25.      If   for   any reason the starting attempt is discontinued, the  entire  starting  sequence must be repeated after allowing the engine to   come   to   a   complete   stop   (1-minute minimum). b.  First engine GEN switch – RESET then ON when N₁ reaches 12%. c.   CONDITION lever (after N₁ stabilizes at or above   12%   for   5   seconds   minimum)   – LOW IDLE.
