TM 1-1510-218-10 8-12 CAUTION If ignition does not occur within 10 seconds after moving condition lever to LOW IDLE, initiate Engine Clearing procedure,   Paragraph   8-25.      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    above    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 engine start, 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. Record peak temperature on DD 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. 4.   Engine and systems instruments – Check. 5.   CONDITION  lever  –  HIGH  IDLE.    Monitor TGT as the condition lever is advanced. NOTE After  starting  the  first  engine  with  a  GPU, the    second    engine    is    normally    started using  a  battery  start.    If  a  GPU   start  is required  or  desired  for  the  second  engine start,  use  the  Second  Engine  Start  (GPU Start) procedure, Paragraph 8-27. Otherwise,   use   the   Second   Engine   Start (Battery Start) procedure, Paragraph 8-23. 6.   GPU disconnect – As required.  Disconnect if   second   engine   start   is   to   be   a   battery start. CAUTION Do    not    turn    on    generators    with    GPU connected. 7.   GEN switch – RESET, then ON. * 8-27.  SECOND ENGINE START (GPU START). 1.   Propeller area – Clear. 2.   Engine – Start. a.   IGNITION     AND     ENGINE     STARTER switch    ON.        IGN    ON    light    should illuminate  and  associated  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,   Paragraph   8-25.      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,   above   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 engine start, the maximum allowable TGT is 1000 °C for 5 seconds.  If this   limit   is   exceeded,   use   Abort   Start procedure,  Paragraph  8-24,  to  discontinue start.    Record  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. 3.   Engine and systems instruments – Check. 4.   Right PROP lever – FEATHER. 5.   GPU – Disconnect. 6.   Right PROP lever – HIGH RPM. 7.   INVERTER switches – ON, check INVERTER lights OFF. 8.   GEN switches – RESET, then ON. 9.   CONDITION levers – As required. 10.  Red anticollision light – Reset.
