TM  1-1520-240-10            8-2-9 LF*  31. 712 First engine  — Start as follows: a.   L MAIN FUEL PUMPS — ON Check L FUEL PRESS Caution Light — OUT. b.   XFEED switch — OPEN. Check R FUEL PRESS Caution Light — OUT. c.   ENG COND lever — STOP. d.   ENG START switch — MTR. NOTE If engine does not reach 15% but exceeds 10% N1 (minimum) and has reached it’s maximum speed, initiate start, but monitor engine and PTIT for possible hung start and/or excessive PTIT. e.   Motor engine to minimum of 15% N1. Set  ENG  COND  lever  —  GND;  ENG START switch to START immediately. f.   Release START switch to MTR before PTIT reaches 200_C. When N1 is 50%, set    START    switch    to    OFF.    Check STARTER ON light out. g.   Engine instruments — Check when sta- bilized at ground idle (N1 at 60_ mini- mum). Check engine oil pressure for 20 psi minimum. The engine should accel- erate  to  ground  idle  speed  within  45 seconds. LF*  32.    ^714A  First Engine — Start as follows: a.   Primary: (1)   L MAIN FUEL PUMP — ON. Check L  FUEL  PRESS  Caution  Light  — OUT. (2)   XFEED switch — OPEN. Check R FUEL   PRESS   Caution   Light   — OUT. (3)   ENG COND lever — GND. (4)   ENG  START  switch  —  Start  and Hold  until  N1  accelerates  to  10% then release. (5)   Engine instruments — Check when stabilized at ground idle (N1 at 50% minimum).  Check  Engine  oil  pres- sure for 5 psi minimum. The engine should accelerate to ground idle with- in 45 seconds. b.   Reversionary ((If engine does not start in PRI and all other indications are nor- mal): (1)   DECU Pre-Start BIT — Perform. (2)   PRI/REV switch — REV. (3)   ENG COND Lever — GND. (4)   ENG  START  switch  —  Start  and hold  until  N1  accelerates  to  10% then release. (5)   Engine instruments — Check when stabilized at ground idle (N1 50 to 60%).  Check  engine  oil  pressure for   5   psi   minimum.   The   engine should  accelerate  to  ground  idle speed within 45 seconds. (6)   DECU BIT — Check 88s (if other than 88, consult DECU Fault Code List/Matrix). (7)   FADEC PRI/REV switch — PRI. CAUTION The N2 section of the second engine starts turning  when  the  first  engine  is  started; however, the lubrication system of the sec- ond engine is driven by the N1 section which does  not  begin  to  turn  until  the  start  se- quence  is  initiated.  Delay  in  starting  the second engine will result in excessive wear on the N2 bearing package and seal. Start the second engine within three minutes of the first. LF*  33.   Second engine — Start by using same meth- od as first engine. * 34.   Transmission  oil  pressures  —  Check  for minimum of 7 psi. There is no time limit for ground idle operation, provided there is a minimum of 7 psi oil pressure in each trans- mission. CAUTION Failure of either engine to accelerate smoothly from ground to flight or engine N1 to accelerate past 70% N1, may be an indication of a clutch malfunction in the engine transmission. *  35.   ENG COND levers — FLT. No. 1 and No. 2 clear to FLT. Engine acceleration should be smooth with no surging. * 36. 712 RRPM   —   Set   as   required. 714A RRPM — Check 100 1. F* 37.  Fluid drain lines — Check. NOTE Delay turning second generator on or off for two seconds. This delay will give DECU time to sam- ple power without causing soft fault.
