Daily maintenance
Youdaoplaceholder0 start preheating ‌
After cold start, run at low speed for 3 to 5 minutes until the water temperature and oil pressure are normal before loading to avoid the risk of cylinder sticking.
Youdaoplaceholder0 shutdown process ‌
First, cut off the load → turn off the main power supply switch → reset the excitation rheostat → stop the engine to prevent voltage surges.
Youdaoplaceholder0 belt adjustment ‌
When pressing the belt with your fingers, it is best if it sinks by 5 to 10mm. If it is too loose, it will slip; if it is too tight, it will accelerate the wear of the bearings.
Youdaoplaceholder0 fuel system maintenance ‌
Regularly check the pressure of the fuel injection pump. The pump head of the diesel pump needs to be cleaned on the outside and lubricated inside to prevent jamming.
Youdaoplaceholder0 crankcase cleaning ‌
Clean with a mixture of diesel and kerosene every 200 hours. Run at low speed for 3 to 5 minutes, then drain and change the engine oil.
Youdaoplaceholder0 winter care ‌
Switch to low pour point diesel (-10#/ -35#) and use 5W-30 engine oil to prevent difficulty in starting at low temperatures.
