TM    9-2350-238-10 OPERATION   IN   UNUSUAL   WEATHER   – CONTINUED EXTREMELY  COLD  WEATHER  –  CONTINUED 1   The   cold   weather   starting   procedures follow: NOTE These   cold   weather   starting procedures   are   normally   used   at 0 °    t o    - 2 5 ° F ( – 1 8 °    t o –31°C),    but    they    also    apply    if vehicle   will   not   start   at   32°   t o 0°F  (0°  to  –  18°C).  For  ex- treme   cold,   –25°F   (–31°C) and   below,   special   purpose   kits should  be  installed  and operated.   Refer   to   Chapter   5. a. Make   sure   batteries   are   fully charged. b.  If   winterization    kit   is  installed,    roll    up and  secure   covers   over   exhaust   ports and  air  intake  grille.  Refer  to  page 5-9.   Turn   coolant   heater   OFF.   Refer to   page   5-5. c. Perform   normal   engine   starting   pro- cedure  steps  1  thru  5.  Refer  to  page 2-52. d.  Push   PRIME-ENGINE-FUEL-FILTERS- AND-HEATER-FUEL-CYCLE  switch (1)  to  heater  fuel  cycle  ON  position, hold  3  to  5  seconds,  and  release.  im- mediately   press   START   switch   (2) and  hold  no  more  than  15  seconds. If  engine  does  not  start,  release START   switch   for   5   seconds   and repeat   step   d   while   performing   step e. NOTE If  engine  does  not  start  on  third attempt,   turn   all   switches   OFF. If   winterization   kit   is   installed, operate   coolant   heater   or   notify unit    maintenance    personnel. e. While   cranking   engine,   operate PRIME-ENGINE-FUEL-FILTER-AND- HEATER-FUEL-CYCLE   switch   (1)   in heater  fuel  cycle  ON  position  for  1 second   then   OFF   position   for   2 seconds    repeatedly. NOTE Observe   instruction   to   cycle   the HEATER-FUEL-CYCLE    switch (1)   on   and   off.   Continuous flame  in  air  box  will  deplete  ox- ygen   supply   to   engine. f. When   engine   starts,   release   START switch   (2)   and   intermittently   activate HEATER-FUEL-CYCLE   switch   (1)   to ON   and   OFF   until   engine   speed   is 300  rpm  or  running  smoothly.  When engine   is   running   smoothly,   release switch   (1). g. If   engine   does   not   start   after   30 seconds   or   indication   of   firing   stops for   over   10   seconds,   stop   cranking and   notify   unit   maintenance personnel. h.  With   brakes   still   locked,   shift transmission  into  4th  range  position, adjust   throttle   to   run   engine   at 1,200   rpm.   Continue   to   run   engine until  coolant  temperature  reaches 120°   to   140°F   (49°C   to   60°C), then   shift   into   N   (neutral)   and   cut engine   speed   to   slow   idle   (650-700 rpm).   If   transmission   temperature   ap- proaches   220°F   (93°C)   during warmup,   stay   in   neutral   until temperature   returns   to   normal. 2-111
