A variety of agricultural machinery to carry out maintenance, maintenance of agricultural machinery, should pay attention to:

1. Some drivers only know to supplement the oil, but ignore the quality inspection. As everyone knows, long-term use of oil contains a lot of oxides and metal shavings, resulting in decreased lubrication performance, parts wear increased. Therefore, the engine should regularly change the oil according to the specified cycle.

2. Some drivers never remove the exhaust pipe and muffler carbon deposition, resulting in too thick carbon deposition, exhaust cross-sectional area decreases, resulting in exhaust emissions, lack of fresh air, combustion deteriorated.

3. Some drivers never remove scale, although the cooling water is full, but the cooling effect is poor, causing a variety of failures.

4. The role of the first oil valve is sealed, about to separate the plunger oil chamber and high-pressure tubing, so as to avoid back flow; Second, to stop the rapid decompression when the fuel supply to ensure that the nozzle off the oil simply. Outlet valve poor quality or wear and tear, it will cause a lot of diesel engine failure.

Valve leakage, people used to check the valve and valve seat, ignoring the valve spring quality inspection. It should be noted that the lack of elastic valve spring is also one of the causes of valve leakage.
