Matters needing attention in daily maintenance

Daily inspection is an important link to ensure the long-term and efficient operation of hydraulic excavators, especially for self-employed, doing daily inspection can effectively reduce maintenance costs.

Turn the machine twice first, and check whether there is any abnormality in the appearance and chassis of the machine, and whether there is oil flowing out of the slewing support. Then, check the bolts and fasteners of the retarder and the crawler. If it is a wheeled excavator, it is necessary to check whether the tires are abnormal and whether the air pressure is stable.

Check whether the bucket teeth of the excavator are seriously worn. It is understood that the wear of bucket teeth will greatly increase the resistance in the construction process, seriously affect the work efficiency and increase the wear of equipment parts.

Check the stick and cylinder for cracks or oil leakage. Check the battery electrolyte to avoid falling below the low level.

The air filter is an important part to prevent a large amount of dusty air from entering the excavator, so it should be checked and cleaned frequently.
