TM 5-1510-220-10 and that the LDG GEAR CONTR handle warning lights (2) illuminate. 24. Fire Protection system Check as follows: a. Fire Detector Test switch Rotate counterclockwise    to    check    three    DETR positions.        FIRE    PULL    handles    should illuminate in each position.  Reset MASTER WARNING in each position. b. Fire Detector Test switch Rotate counterclockwise    to    check    two    EXTGH positions.    SQUIB  OK  light,  associated  #1 EXTGH   DISCH   and   #2   EXTGH   DISCH annunciator    caution    light    and    MASTER CAUTION LIGHT should illuminate in each position. 25. INS Align as required. 8-29.  * FIRST ENGINE START (BATTERY START). NOTE The   engines   must   not   be   started until after the INS is placed into the NAV mode Or OFF as required. Starting  procedures  are  identical  for  both  engines. 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    receptable    being    located    adjacent    to    the    right engine.      A   crewmember   should   monitor   the   outside observer throughout the engines start. 1. Avionics master switch OFF. 2. Exterior light switches As required. 3. Propeller Clear. 4. Ignition  and  engine  start  switch  ON.    Propeller should begin to rotate and associated #1 IGN ON or #2 IGN ON annunciator light should illuminate. Associated #1 FUEL PRESS or #2 FUEL PRESS light should extinguish. CAUTION 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). 5. Condition   lever   (after   N1   RPM   stabilizes,   12% 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 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. 6. TGT and N1 Monitor (TGT 1000°C maximum, N1 52% minimum). 7. Oil pressure Check (60 PSI minimum). 8. Ignition  and  engine  start  switch  OFF,  after  50% N1. 9. Condition  -lever  HI  IDLE.    Monitor  TGT  as  the condition lever is advanced. 10. Generator switch RESET, then ON. 8-30.  * SECOND ENGINE START (BATTERY START). 1. First engine generator load 50% or less. 2. Propeller Clear. 3. Ignition  and  engine  start  switch  ON.    Propeller should begin to rotate and associated #1 IGN ON or #2 IGN ON annunciator light should illuminate. Associated #1 FUEL PRESS or # 2 FUEL PRESS annunciator light should extinguish. 8-12
