HANDLING OF ENGINE
Inspection Method After the Engine Started
Avoid a quick increase of engine speed or load immediately after the engine is
started. First, idle the engine for about 10 minutes, and then check the operating
status of instruments and warning lights. Also, check for abnormal vibration from the
engine, noise, and the conditions of smell and color in the exhaust gas.
CAUTION
In the cold season, immediately after the engine is started, the operating
sound of the engine may be slightly louder, and the smoke of the exhaust gas
may increase, but this is not abnormal.
When the engine is not sufficiently warmed up, the engine oil is not supplied
adequately, and a breakdown may result. Be practically careful in the cold
season.

Engine Oil Pressure
When the engine oil pressure gauge is equipped, after the engine is warmed up,
confirm that the gauge reads the appropriate values during the idling speed operation
and the rated speed operation.
ADVICE
Since the oil temperature is low immediately after the engine is started, take
measurements after the engine is warmed up.
•
Engine oil pressure
Proper value*
During idling speed operation 147 kPa (1.5 kgf/cm²/21 psi) or more
During rated speed operation 294 kPa (3.0 kgf/cm²/43 psi) or more
* The values vary depending on the oil temperature and the oil type.
