5.1.6. 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.
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 con-
necting parts of turbocharger inlet, and
operate the starting motor until oil
comes out the connecting parts.
Care must be paid that after the con-
firming above, retighten the pipe con-
necting parts without fail, and proceed
with the normal starting.
1)
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 abnor-
mal wear or stuck may be caused.
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.
2) Various inspections must insure that
there are no leakage of oil, gas and air.
1) Sudden load at time soon after engine
starting and at the state when turbo-
charger did not yet reach to smooth rev-
olution , if abrupt load is applied to
engine, some parts where oil did still not
reach may cause a burn to be stuck.
2) If there are the leakage of oil, gas, air,
particularly oil, for the oil pressure low-
ers, it causes a burn of bearing to be
stuck.
During operation Following items must be confirmed.
1)
Oil pressure at
idling: 0.9 ~ 3.0 bar
at full load: 3.0 ~ 6.5 bar
2) When abnormal noises and vibration
are generated, slow down the revolution
and must stop it to investigate the
causes.
1) If the pressure is too low, abnormal
wear or stuck may be caused. Or if too
high, the oil leak may be generated.
2) If the engine operation were continued
with abnormal noises and vibration, it
causes the engine trouble that can not
be repaired or some other troubles.
