TM 5-3895-373-10 CAUTION Starter motor may overheat if operated  longer  than  30  seconds.    If engine does not start, allow starter to cool  for  two  to  three  minutes  before trying  again.    If  engine  fails  to  start after three attempts, notify Unit Maintenance. i. Turn  the  ignition  switch  to  the  START    position and immediately release when the engine starts. The switch will spring return to the ON position. CAUTION Incorrect     oil     pressure     can     cause engine damage. If    gauges    do    not    display    proper readings,     shut     down     engine     and correct malfunction before operation. j. Check   engine   oil   pressure.      If   no   engine   oil pressure  develops,  immediately  shut  down  the engine.    Engine  oil  pressure  gauge  should  read 10 to 15 psi (0,9 to 1,3 bar) minimum at low idle and  30  to  100  psi  (2,6  to  8,6  bar)  maximum  at high idle. k. Disconnect  the  slave  cable  from  both  vehicles and install slave receptacle covers. CAUTION Incorrect  oil  pressure  or  temperature can cause engine damage.  If gauges do  not  display  proper  readings,  shut down engine and correct the malfunction before operation. Do   not   idle   unnecessarily   for   long periods   of   time.      Idling   the   engine unnecessarily    for    long    periods    of time   wastes   fuel   and   fouls   injector nozzles. Unburned fuel causes carbon     buildup,     oil     dilution,     and formation of lacquer or gummy deposits  on  the  valves,  pistons,  and rings. I. After     startup,     observe     engine     gauges     and warning lights for proper readings. Gauge Reading (Low Idle) RPM 560 to 850 Oil Pressure 10 to 15 psi (0,9 to 1,3 bar) Coolant Temperature 1700 to 200°F (770 to 930C) Hydraulic Oil Temperature 100° to 200°F (38° to 930C) Voltage 12 to 14 VDC m.    Run  the  engine  at  IDLE  for  five  minutes  before paving operation begins.  Do not race the engine during the warmup period. 2-110
