5.3.4. How to handle the engine
1) Precautions for operation of the engine
Operation following items must be observed at the starting, operation and stop of
engine.
Operation Caution Reason
At starting
1) Inspect oil quantity
2) After confirming that oil pressure
rises by starting engine with starter
(until the pointer of oil pressure gauge
moves or pressure indicating lamp
operates), the starting must be done.
2) If engine is started quickly, of course
beginning with every parts of engine,
for it revolves without oil that is to
reach to the turbocharger, the
bearing's abnormal wear or stuck
may be caused.
3) In case that oil, oil filter and
lubricating system's part are
replaced or engine was stalled for
long time (more than a week), and
in case of operation under cold
weather, loosen the oil pipe
connecting parts of turbocharger
inlet, and operate the starting
motor until oil comes out the
connecting parts. Care must be
paid that after the confirming
above, retighten the pipe
connecting parts without fail, and
proceed with the normal starting.
3) In case that engine stalled for long
time and of cold weather, the fluidity
of oil may be get worse.
Immediately
After starting
1) Perform idling operation for about
5 min. immediately after engine
starting.
1) Sudden load at time soon after engine
starting and at the state when
turbocharger did not yet reach to
smooth revolution, if abrupt load is
applied to engine, some parts where
oil did still not reach may cause a
burn to be stuck.
2) Various inspections must insure
that there are no leakage of oil,
gas and air.
2) If there are the leakage of oil, gas,
air, particularly oil, for the oil pressure
lowers, it causes a burn of bearing
to be stuck.
