20 Small Habits of Excavator Maintenance

Maintenance is a prerequisite for keeping the excavator healthy and efficient. Do you know 20 small habits of excavator maintenance? Please follow this article to find out.

Engine maintenance
1. Engine oil and oil filter elements must use regular brand products, and they must be checked regularly and replaced in time;
2. The air filter needs to be checked frequently. When there is a lot of dust on the outer filter element and it is necessary to use compressed air to blow the air pressure from the inside to the outside, the air pressure should not be too high to prevent the filter element from being blown out. The inner filter cannot be cleaned. After cleaning the outer filter two or three times, it needs to be replaced together with the inner filter;
3. It is better to use diesel fuel provided by regular gas stations. At the same time, diesel oil needs to be filtered before being added to the fuel tank (the more common method is to put socks on the fuel tank)
4. To prevent carbon deposits, please do not leave the machine in the state of idling for long-term use for the purpose of saving fuel.
Hydraulic maintenance
5. Hydraulic oil, oil return filter element, and pilot filter element are vulnerable parts, which should be checked and replaced regularly.
6. When there is a lack of hydraulic oil, add it in time.
7. Pay attention to exhaust the air after replacing the hydraulic oil or hydraulic components of the machine.

Electrical maintenance
8. Excavators should not work in deep water;
9. Do not pile up sundries in the battery box of the excavator, so as not to cause a fire;
10. Do not use iron or copper wire as a substitute for fuses. Also do not substitute substandard insurance products;
11. When the excavator is parked for a long time, the battery line should be removed to prevent power loss.

Mechanical maintenance
12. Regularly check the slewing reducer, travel reducer and other components of the excavator and replace the gear oil;
13. Pay attention to clean up the mud and debris on the pin shaft part, and add mechanical lubricating oil.
14. Remember to replace the lubricating oil in the rotary ring gear in time after the wading operation. This is because during wading operations, water will overflow the rotary ring gear, causing the lubricating oil to deteriorate, which in turn affects the working efficiency of the machine.
15. Pay attention to the rust prevention of the cylinder rod.
16. When the excavator is parked for a long time, the exposed metal parts should be coated with lubricating oil to prevent rust.

Maintenance of structure
17. Check the pin shaft bolts of the excavator every day for looseness or loss, and tighten them in time.
18. Check the structure for cracks and deformation every day.
19. Pay attention to the surrounding environment when parking the excavator, park it on a solid and stable ground, and do not park it by the river, cliff or under the hillside.
20. When parking the excavator, the bucket cylinder needs to be fully retracted and the bucket landed to prevent the cylinder from being hit.
