Operation of engine
●
After the engine is started, reduce the throttle opening immediately to enable the engine to be in idling state,
and inspect the engine oil pressure at this moment to ensure that the engine oil pressure is not lower than
98kPa(1 kgf/cm ² ). At this moment, the oil pressure indicator light is off.
●
After the engine is started, do not have the engine operated at full load immediately, but have the engine
operated at middle speed for warm-up. When the coolant temperature is more than 60
℃
, the engine speed can
be increased to the maximum value, and be operated at full load.
●
The engine speed and load should be increased/decreased slowly, especially after the engine is started, do not
allow to "fiercely step throttle" to make the engine to be run at high speed.
●
When the engine is running, the engine pressure and coolant temperature should be inspected from time to
time, and the cooling temperature during normal operating of the engine should be kept at about 85 ～ 95
℃
.
The engine oil pressure should be 294
～
490 kPa.
Important:
The engine oil pressure cannot be lower than 98kPa in any circumstance, and if the pressure is lower than
the same value, it is required to investigate causes and conduct troubleshooting.
