4. CARE IN THE ENGINE OPERATION
In the engine operation, always pay attention to the following items
if the engine indicates any sign of abnormalities.
(‘1)
Engine Oil Pressure
Engine oil pressure is normal when the oil pressure gauge
shows 290 to 590 kPa (43 to 85 psi) in the engine warmed-up
condition., although the engine oil pressure may vary depending
on a type of oil or the engine specification.
In the continuous engine operation, engine oil pressure is
slightly lower than the pressure at start-up time.
If, in continuous engine operation, the engine oil pressure
warning lamp is off, engine oil pressure is normal.
When the engine oil pressure gauge shows the following
abnormal conditions, stop the engine immediately and check
the engine oil amount in the oil sump and oil leakage:
l
The engine oil pressure gauge shows below 200 kPa (28 psi)
though the engine speed is raised.
l
The oil pressure gauge indicator oscilates greatly in the
engine low speed range.
l
When the engine oil pressure warning lamp goes on and off
repeatedly.
When no lack of engine oil or no oil leakage is found, contact
your equipment supplier to determine the cause of the
abnormal reading.
