Backhoe loaders are mainly used for filling and excavation of roadbed engineering, aggregate and loading of asphalt and cement concrete yards during highway construction. Due to the advantages of fast operating speed, good maneuverability, and easy operation, the backhoe loader has developed rapidly and has become the main machine in earthwork construction. Therefore, the daily maintenance of the backhoe loader is particularly important.


1. Because the backhoe loader is a special vehicle, the operator should receive training and guidance from the manufacturer, have a full understanding of the structure and performance of the machine, and obtain certain operation and maintenance experience to operate the machine. The "Product Operation and Maintenance Manual" provided by the manufacturer is necessary information for the operator to operate the equipment. Before operating the machine, be sure to read the "User Maintenance Manual" and carry out operation and maintenance as required.
2. The backhoe loader needs to pay attention to the working load during the running-in period. Half of the working load during the running-in period should not exceed 60% of the rated working load, and a suitable workload must be arranged to prevent the overheating site caused by the continuous operation of the machine for a long time. occur.
3. Pay attention to the indications of all the instruments frequently. If there is any abnormality, stop the vehicle in time to eliminate it. Stop the operation before the cause is found and the fault is not eliminated.
4. Pay attention to frequently check the level and quality of lubricating oil, hydraulic oil, coolant, brake fluid and fuel oil (water), and pay attention to check the tightness of the whole machine. During the inspection, it was found that there was too much oil and water, and the cause should be analyzed. At the same time, the lubrication of each lubrication point should be strengthened. It is recommended that the lubrication point should be filled with grease (except for special requirements) during each shift during the run-in period.
5. It is necessary to keep the backhoe loader clean and adjust and fasten the loose parts in time to prevent the parts from being worn out or causing the parts to be worn or lost.
6. When the running-in period of the backhoe loader is over, compulsory maintenance should be performed on the machine, and the inspection and adjustment work should be done. At the same time, pay attention to the replacement of the oil. In short, the requirements for the use and maintenance of the loader during the running-in period can be summarized as: strengthen training, reduce load, pay attention to inspection, and strengthen lubrication.

As long as the maintenance and maintenance of the backhoe loader are carried out during the break-in period as required, the occurrence of early failures will be reduced, the service life will be extended, the operating efficiency will be improved, and the backhoe loading opportunities will bring you more benefits.
