1. Cleaning the tractor. Frequent cleaning can keep the tractor clean and prevent dust and debris from entering the machine when fuel or lubricating oil is added. And it can discover hidden dangers in time to prevent blockage, damage and parts corrosion. Therefore, after each shift, the dust and oil on the outside of the tractor must be carefully removed before other maintenance work can be carried out.

2. The lubricating grease should be filled with fresh grease in accordance with the lubrication point, oil filling interval and quantity specified in the technical maintenance regulations. During filling, the actual amount of grease injected is often insufficient due to the presence of air in the grease gun. Therefore, it is necessary to ensure the amount of grease injected.

3. Maintenance of filter device. Air, fuel, and lubricating oil filters are the key to retaining impurities and reducing mechanical wear. Regular cleaning and replacement of filter elements are key items for maintenance.
The maintenance of the air filter is mainly to remove the dust in the accumulation cup, clean the central air inlet pipe, clean the filter screen and the oil pan, and change the oil.
After the paper filter element of diesel and oil filter is used for a long time, the impurities are trapped in the surface pores, gradually reducing the filtering performance, increasing the pressure difference between the inside and outside of the filter element, and even squeezing or crushing the folded sheet. an examination. When the blockage of the filter element is not serious, it can be immersed in diesel oil and blown from the inside out with air to restore its filtering performance; when the blockage is serious, it should be replaced.

4. Adding and replacing engine oil. A small amount of tractor oil will be consumed during use. Therefore, it should be checked every time before starting, and if necessary, make up according to the scale of the oil dipstick. There are two upper and lower marks on the dipstick. The oil capacity between the two marks is for regular consumption under normal operation. Usually the oil level should be between the two engraved lines and close to the upper engraved line.
The engine oil is oxidized at high temperature during use, resulting in colloids, carbon deposits, and abrasion debris, resulting in deterioration, dirt, and poor lubrication of the engine oil. Therefore, after a certain period of time, the oil should be replaced in accordance with the requirements of the technical maintenance regulations. Otherwise it will accelerate the oil wear.

5. Clean the engine oil passage. While changing the oil, clean the oil passage to remove the dirty oil and dirt remaining in the lubricating passage, otherwise, it will contaminate the newly added oil and reduce its quality.

6. Remove the scale of the cooling system. The engine cooling system requires the use of clean soft water, whose purpose is to delay the formation of scale and ensure heat dissipation efficiency. Otherwise, the formation of scale in the cooling system will cause the engine to overheat due to poor heat dissipation and insufficient power. In serious cases, it will also cause accidents such as tile burning and cylinder pulling. Therefore, keeping the cooling system clean and removing the scale of the cooling system is an operation item that cannot be ignored.
