Maintenance

1.Engine oil needs to be replaced regularly, with a general replacement cycle of 500 hours.

2. Hydraulic oil should be replaced according to the prescribed maintenance cycle, which is 2,500 to 3,000 hours.

3. Timely addition of lubricating grease can effectively reduce the wear of each component and ensure smooth operation of all components.

4. Regularly clean or replace the air filter element and air filter to ensure that the engine sucks in clean air and improve fuel efficiency. In harsh working conditions such as heavy dust, the frequency of inspections should be increased.

5. Check the coolant level to keep the cooling system unobstructed and prevent overheating.

6. Clean the radiator. When an excavator is in operation, it generates a large amount of heat. The cleaning of the radiator is very important for maintaining the normal operation of the engine.

7. Tracks are important components of excavators. Appropriate track tension can extend the service life of tracks. Regularly inspect and adjust the tension of the tracks to ensure they are within a consistent standard range.

8. The transmission system is an important component of an excavator. Regular checks should be conducted on the transmission chain, gears and other parts, and severely worn components should be replaced in a timely manner.Through the above daily maintenance measures, faults can be effectively prevented, the service life of excavators can be prolonged, and the safety and smooth progress of work can be ensured.
