4.3. Inspections After Starting
During operation the oil pressure in the engine lubrication system must be monitored. If the
monitoring devices register a drop in the lube oil pressure, switch off the engine immediately.
And the charge warning lamp of the alternator should go out when the engine is running.
•
Do not disconnect the battery or pole terminals or the cables.
•
If, during operation, the battery charge lamp suddenly lights up, stop the engine immediately
and remedy the fault in the electrical system.
•
Engine should be stopped if the color, the noise or the odor of exhaust gas is not normal.
•
Confirm the following things through warning lamps and gauge panel.
4.3.1. Pressure of lubricating oil
The normal pressure comes up to 1 kg/cm
2
(1.0 bar) at idling and 3 ~ 5 kg/cm
2
(3.0 ~ 4.9 bar)
at maximum speed. If the pressure fluctuates at idling or does not reach up to the expected
level at high speed, shut down the engine immediately and check the oil level and the oil line
leakage.
4.3.2. Temperature of cooling water
The cooling water temperature should be 79 ~ 95 °C in normal operating conditions.
Abnormally high cooling water temperature could cause the overheating of engine and the
sticking of cylinder components. And excessively low cooling water temperature increases the
fuel consumption, accelerates the wears of cylinder liners and shortens the engine life-time.
