F-137 TM 10-3930-671-24 STARTING PROCEDURE Starting  fluids  or  aids  such  as  ether or   gasoline   must   not   be   used   In   a diesel  engine  air  Intake  system.    The use  of  these  fluids  will  cause  severe Internal engine damage and/or bodily Injury.    Read  and  observe  warnings on pages 1 and 2. 1. Ensure  speed  selector  is  in  NEUTRAL  position. Starting  engine  under  load  throws  overload  on starter and battery. 2. Make sure electric shut-off is wired to permit fuel flow  when  the  starter  switch  is  in  the  "START" and "RUN" positions. 3. If   the   fuel   pump   is   fitted   with   a   mechanical shutoff, move the control to full open. 4. Move switch to START position and start engine. 5. Adjust throttle to idle at 800 to 1200 R.P.M.  for a few minutes to circulate and Warm the oil.  Then open throttle to about half speed until the coolant reaches 38°C (100°F). 6.    If  engine  fails  to  start,  turn  switch  to  the  "OFF position and repeat the above steps.  If starting is not attempted within 15 to 20 seconds, repeat the pre-heat sequence. 7.    If  engine  still   does   not   start   refer   to   Trouble Shooting, Section 9. 8.    Check Oil Pressure. MODEL OIL PRESSURE TMD 2.8 - 4.1 Bar (40 - 60 PSI) *Higher oil pressure my be experienced during cold starts. 9.    Check Water Temperature. 10.    CAUTION:  After starting new engine - run it at idle for 5 minutes, then stop engine and recheck oil level in crankcase - then bring oil level to high mark on dipstick. IMPORTANT! Breaking in a new or rebuilt engine for peak   performance   and   economical   operation,   the following adjustments should be made at end of first 50 hr.  operation. 1. Adjust valve tappets to specified clearances. 2. Adjust   idle   speed   to   equipment   manufacturer's recommendation. WARM-UP NEW ENGINES When   new   engines   in   distributors'   or   dealers'   stock, showrooms,  etc.    are  started  up  for  any  reason,  they should be brought  up  to  operating  temperature  in  order to eliminate all condensation before stopping. If  they  are  stopped  while  still  cold,  condensation  will settle   on   valve   stems   and   guides,   as   well   as   other moving   parts,   and   rust   and   sludge   will   form.      Soon valves,  rings,  etc.    will  be  stuck   by   this   rusting   and sludging action. Engine should be operated long enough to bring oil and water  temperature  to  normal  operating  temperature;  be sure breather or ventilation system is open so vapor can be expelled. F-138
