TM 5-4210-230-14&P-1 VEHICLE OPERATION GASOLINE ENGINE-AUTOMATIC CHOKE Set parking brake and place transmission control in the neutral position. If engine hasn't run for several hours and is cold, press the   accelerator   pedal   once   all   the   way   to   the   floor   for   a moment and then release it.  This sets the automatic choke to give  the  engine  a  "rich"  fuel  mixture  for  cold  starting.    If  the engine  has  been  stopped  for  only  a  short  time  and  is  still relatively  warm,  don't  set  the  choke.    Otherwise,  you  may flood  a  warm  engine  with  too  much  gasoline  and  actually prevent  it  from  starting.    Just  depress  the  accelerator  pedal, about one-fourth of its downward travel and keep it there while starting  the  engine.    Don't  pump  the  accelerator  pedal,  you'll only  flood  the  engine.    If  this  should  happen,  however,  the engine will usually start if the pedal is pushed and held all the way to the floor while operating the starter. Depress  the  clutch  pedal  and  keep  it  depressed  until the engine is running. After  a  cold  engine  starts  to  warm  up  and  is  running smoothly,   tap   accelerator   pedal   sharply   with   your   foot   to reduce fast idle speed. GASOLINE ENGINE-MANUAL CHOKE 1. Set parking brake. 2. Place transmission control in the neutral position. 3. Depress  accelerator  once  all  the  way  to  the  floor  and hold.    Pull  choke  control  out  full  distance  and  release accelerator.      Do   not   use   the   choke   when   engine   is warm. 4. Depress  clutch  pedal  and  keep  it  depressed  until  the engine is running. 5. Start Engine. 6. Immediately after engine starts adjust choke control for proper    fast    idle    speed    and    mixture    control.        The frequent use of the choke control dilutes the crankcase oil.    For  this  reason,  we  recommend  a  more  frequent complete  oil  change  in  winter,  using  new  oil  of  good quality. 7. Push  the  choke  control  all  the  way  in  as  soon  as  the engine warms up and operation permits. LPG ENGINE COLD 1. Slowly open only the vapor valve on one fuel tank.  It is important   that   the   vapor   valve   be   opened   slowly, otherwise the excess flow valve at the tank or in the line may be "slugged" or automatically closed. Approximately  50  seconds  are  required  for  the  excess flow valve to relieve itself. 2. Press  primer  control  on  dash  two  or  three  times.    A manual operated primer plunger is also provided on the converter for priming the engine under the hood. 3. Push  in  clutch  pedal  and  hold  in  until  after  engine  is started. 4. Start  Engine.    If  the  engine  fails  to  start  or  makes  a false start do not try starting again until the engine has come to a complete stop. 5. As   soon   as   engine   starts,   press   accelerator   pedal slightly to pick up engine control.  To press accelerator before engine starts will make starting more difficult. 6. After    the    engine    warms    up    to    normal    operating temperature, slowly turn the liquid valve at tank on and the vapor valve off. LPG ENGINE WARM 1. Slowly open the liquid valve on one tank only. 2. Do not use the primer control. 3. Start   Engine,   in   the   same   manner   as   described   in Items 4 and 5 of Cold Start Procedure. ENGINE WARM UP It   is   very   important   that   any   engine   be   warmed   up before applying load. The warm-up period provides time for the lubricating oil to establish a film between moving parts. In   colder   areas   where   temperature   is   often   below   0 deg.      C   (32   deg.F),   the   warm-up   period   for   turbocharged engine  is  especially  important.    The  cold  external  oil  lines leading to the turbocharger will tend to slow oil flow until the oil warms up. Slow   oil   flow   to   the   turbocharger   reduces   the   oil available  for  the  bearing;    therefore,  before  applying  load  or speed above 1000 rpm to the engine make sure to: WARM  UP  THE  ENGINE  FOR  A  MINIMUM  OF  FIVE MINUTES  AT  OR  BELOW  1000  RPM  BEFORE  APPLYING LOAD. 6
