1、 Precautions for engine use
1. After a new engine or overhaul, the diesel engine cannot work at full load and high speed at the beginning. It can only be put into normal operation after running in at low speed and light load for 50 hours.
2. Keep the fuel clean. If necessary, it shall be precipitated or filtered with silk cloth.
3. Maintain normal water temperature (70 ~ 85 ℃) and oil pressure (0.2 ~ 0.4MPa at medium speed).
4. In case of any abnormality during operation, stop the machine immediately for inspection.
5. "Hard water" should not be used as cooling water to prevent scale and reduce the service life of the engine.
2、 Daily maintenance
1. Check whether the oil level in the oil pan is between the two scribed lines of the oil scale and close to the upper scribed line. After the new engine or the diesel engine that has been out of service for a long time is filled with oil to the upper scribed line, stop after running at low speed for 5 ~ 10 minutes, and measure the oil level again with an oil dipstick.
2. Check the water volume of the water tank.
3. Check the oil level in the fuel injection pump and replenish it to the specified position if it is insufficient.
4. Eliminate three leakage (oil, water and gas).
5. Check the firmness of components, accessories and devices.
6. Check the cleanliness, remove oil and dust, and pay special attention to the drying and cleaning of electrical equipment.
7. After 50 hours of light load operation of the new machine, replace the engine oil (including the engine oil in the fuel injection pump) and the engine oil filter element in time, and clean the oil pan and engine oil filter collector.
8. Timely protection of daily lubricating oil additives.
