TM 55-1510-220-10 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). 4. Condition lever (after N1 RPM passes 12% 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. 5. TGT and N1 Monitor (TGT 1000°C maximum, N1 52% minimum). 6. Oil pressure Check (60 PSI minimum). 7. Ignition  and  engine  start  switch  OFF  after 50% N1. 8. Battery   charge   light   Check   (light   should illuminate   approximately   6   seconds   after generator  is  brought  on  line.    Light  should extinguish    within    5    minutes    following    a normal engine start on battery). 9. Inverter   switches   ON,   check   INVERTER annunciator lights extinguished. 10. Second engine generator RESET, then ON. 11. Condition levers As required. 8-31.  ABORT START. 1. Condition lever FUEL CUTOFF. 2. Ignition and engine start switch STARTER ONLY. 3. TGT Monitor for drop in temperature. 4. Ignition and engine start switch OFF. 8-32.  ENGINE CLEARING. 1. Condition lever FUEL CUTOFF. 2. Ignition  and  engine  start  switch  OFF  (5  minute minimum). CAUTION Do  not  exceed  starter  limitation  of 30 seconds ON and 5 minutes OFF for two starting attempts and engine  clearing  procedure.    Allow 30   minutes   off   before   additional starter operation. 3. Ignition and engine start switch STARTER ONLY (15 seconds minimum, 30 seconds maximum). 4. Ignition and engine start switch OFF. 8-33.  * FIRST ENGINE START (GPU START). 1. INS As required. NOTE The   engines   must   not   be   started until after the INS is placed into the NAV mode or OFF as required. 2. Avionics master switch As required. 3. Exterior light switches ·  As required. 4. Propeller Clear. 5. Ignition  and  engine  start  switch  ON.    Propeller should begin to rotate and associated #1 IGN ON or  #2  IGN  ON  should  illuminate.    Associated  #1 FUEL    PRESS    or    #2    FUEL    PRESS    warning annunciator light should extinguish. 6. Condition  lever  (after  N1  RPM  stabilizes,  12%, minimum) LOW IDLE. 8-13
