What should be paid attention to when using the air filter

What should be paid attention to when using the air filter? The specific analysis is as follows:

1. Oil shall be filled before putting into operation, and the model of oil shall be the same as that of the engine used in the same period.

2. Fill the oil pan with oil to the oil level line (about 4L for general oil), and do not overfill.

3. Change the engine oil every 250 hours in general areas: when the oil pan is shaken and the engine oil is not easy to flow, it is necessary to clean the filter element of oil bath and change the engine oil. Under the extremely bad service conditions, it must be checked every day.

4. Every 750 hours of driving: maintain the paper main filter element; if the paper main filter element is damaged, replace it with a new paper main filter element immediately, and replace the secondary filter element at the same time.

5. Every 3000 hours or a year: replace the paper main filter element and secondary filter element at the same time.

6. In complex and harsh environment (dusty and humid), the above maintenance interval shall be halved.

7. When the user changes the filter element, the original filter element must be replaced.
