TM 1-1510-218-10 8-10 b.   ANNUNCIATOR  TEST   switch   –   Press and  hold.    Check  that  all  lights  in  both annunciator  panels,  FIRE  PULL  handle lights,   marker   beacon   lights,   MASTER CAUTION,    and    MASTER    WARNING lights   are   illuminated.      Release   switch and  check  that  all  lights  except  those  in step a are extinguished. c.   MASTER CAUTION and MASTER WARNING  lights  –  Press  and  release. Both lights should extinguish. H 19.  Stall and gear warning system – Check as follows: a.   STALL   WARN   TEST   switch   –   TEST. Check that warning horn sounds. b.   LDG    GEAR    WARN    TEST    switch    – TEST.  Check that warning horn sounds and   that   the   two   LDG  GEAR  CONTR handle warning lights illuminate. 20.  Engine fire protection system  – Check as follows: a.   FIRE    PROTECTION    TEST    switch    – Rotate switch counterclockwise to check three    DETR    positions.        FIRE    PULL handles should illuminate in each position.    MASTER  WARNING  must  be reset in each position. b.   FIRE DETECTOR TEST switch – Rotate switch   counterclockwise   to   check   two EXTGH   positions.       SQUIB   OK   light, associated  EXTGH  DISCH  caution  light, and    MASTER   CAUTION    light    should illuminate in each position. 8-22.  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.    When making   a   Ground   Power   Unit   (GPU)   start,   the   left engine    should    be    started    first    due    to    the    GPU receptacle  being  located  adjacent  to  the  right  engine. Normally, only one engine is started utilizing the GPU, reverting to the Battery Start procedure for the second engine   start.      A   crewmember   should   monitor   the outside observer throughout the engine start. 1.   EXTERIOR LIGHTS switches – As required. 2.   Propeller – Clear. 3.   Engine – Start. a.   IGNITION     AND     ENGINE     STARTER switch   –   ON.      IGN   ON   light   should illuminate  and  associated  FUEL  PRESS light should extinguish. CAUTION If    the    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 (1-minute minimum). b.   CONDITION lever (after N₁ RPM stabilizes,  12%  for  5  seconds  minimum) – LOW IDLE. CAUTION 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   starting,   the   maximum   allowable TGT is 1000 °C for 5  seconds.   If  this  limit is   exceeded,   use   Abort   Start   procedure, Paragraph    8-24,    and    discontinue    start. Enter  the  peak  temperature  and  duration on DA Form 2408-13-1. c.   TGT  and  N₁  –  Monitor  (TGT   1000   C maximum N₁ 52% minimum). d.   Oil pressure – Check (60 psi minimum). e.   IGNITION     AND     ENGINE     STARTER switch – OFF after 50% N₁. 4.   Engine and systems instruments – Check. 5.   CONDITION  lever  –  HIGH  IDLE.    Monitor TGT as the condition lever is advanced. CAUTION Ensure N₁ has  reached  at  least  HIGH  IDLE RPM before turning on generator. 6.   GEN switch – RESET, then ON. 8-23.  SECOND ENGINE START (BATTERY START). 1.   First  engine  generator  load  50%  or  less  – GEN switch OFF. 2.   Propeller – Clear. 3.   Engine – Start.
