TM5-2430-200-10 57 Operation Section Engine Starting Engine Starting Below -32⁰C (-25⁰F) DO  NOT  SPRAY  ETHER  or  other  starting  fluids  into the air intake. This diesel engine is equipped with an   electric    air    intake    heater    system    to    aid    cold   weather  starting  and  reduce  white  smoke.  Do  not spray  ether  into  the  air  inlet.  It  could  contact  the heater elements and cause an explosion. Use ONLY the  start-aid  system  or  immediate  engine  damage and personal injury may result. Do   not   operate   the   engine   coolant   heater   in   an enclosed   area.   The   heater   produces   combustion gases    which    may    be    harmful    to    your    health.   Always   start   and   operate   the   heater   in   a   well- ventilated  area  and,  if  in  an  enclosed  area,  vent  the exhaust to the outside. 1.  Press switch (1) to start the engine coolant heater.   An indicator in the switch illuminates when the engine coolant heater is ON. Allow the engine   coolant heater to operate for 40 minutes. 2.  Press switch (1) to shut the engine coolant heater off. Wait for three minutes before attempting to start   the engine. NOTICE Do  not  start  the  engine  for  three  minutes  after  using   the  engine  coolant  heater.  The  engine  coolant  heater requires  three  minutes  to  complete  the  shutdown  cycle. Damage  to  the  engine  coolant  heater  may  result  if  the engine is started without a three-minute wait to purge the system. 3.  Follow Steps 1 and 2 of “Engine Starting Between   0⁰C and -32⁰C (32⁰F and -25⁰F)” in this section.   4.  Hold the engine start switch in the START position. 5.  After five to ten seconds of cranking, inject ether by pressing and holding the start-aid switch for three seconds, and then releasing it. Repeat the injection   of ether every 10 to 15 seconds while cranking the engine. NOTICE Do  not  keep  the  starting  motor  engaged  for  more  than   90   seconds   at   a   time.   Wait   one   minute   to   allow   the starting  motor  to  cool  before  trying  to  start  the  engine again.  If  the  engine  does  not  start  after  three  attempts, determine  the  cause  of  the  malfunction.  Pumping  the accelerator pedal will not assist in starting the engine. 6.  Release the engine start switch into the ON position after the engine reaches 1000 rpm. If the engine   runs roughly, operate the start-aid switch manually   to inject ether sparingly until the engine is running smoothly. NOTE:   The ECM will disengage the starter at 600 rpm. Holding the starter engaged after the engine has started will not damage the starter. NOTICE Do   not   increase   engine   speed   until   the   oil   pressure gauge  indicates  normal  (between  250  and  450  kPa  (30 and 70 psi)). The engine oil pressure indicator should go off,  and  the  oil  pressure  gauge  should  raise  within  15 seconds  after  the  engine  starts.  If  oil  pressure  is  not indicated  on  the  gauge  within  15  seconds,  do  not  drive the machine. Stop the  engine, and report the problem to Unit Maintenance. Do not operate the machine until the problem has been corrected. NOTE:   Applying a light load will help the engine reach normal operating temperature sooner. When idling in cold weather, the ECM may increase the engine speed to approximately 1000 to 1200 rpm. Do not race the engine to speed warm-up.
