Before starting and during the operation of the diesel engine, the Yuchai 450 kW Diesel Generator Set must have sufficient engine oil to prevent cylinder scuffing and bearing burnout caused by oil shortage. During the operation of the Yuchai 450 kW Diesel Generator Set, attention should be paid to observing the condition of the oil pressure gauge or oil pressure indicator light. 

 If the Yuchai 450 kW Diesel Generator Set operates when the cooling water volume is insufficient or the temperature of cooling water and engine oil is too high, insufficient cooling water volume of the diesel engine will reduce its cooling effect, and the diesel engine will overheat as it cannot obtain effective cooling.
