Do maintenance, no failure, in order to improve construction efficiency
1. The operator should always pay attention to the working state of the small excavator, and be good at identifying frequent failures. After a failure, it is not enough to just repair it. We also need to understand the cause of the failure to avoid secondary occurrences in the future.
2. Generally speaking, most of the sudden failures are gradual failures caused by the hydraulic oil being too dirty or the spring being broken and the valve is not tightly closed. Most of them are caused by serious wear of components or aging of rubber seals and pipe fittings. So we have to do regular inspections
3. The sound of normal machine operation has a certain rhythm and rhythm, and remains stable. Therefore, become familiar with and master these laws and keep them steady. Therefore, if you are familiar with and master these laws, you can accurately diagnose whether the hydraulic system is working properly.
4. When there is a failure of hydraulic oil leakage, after eliminating the insufficient or uneven torque of the fastening bolts, before replacing the oil seal that may have been severely worn or damaged, it should also be checked whether the pressure exceeds the limit. When installing the oil seal, the model and quality of the oil seal should be checked and assembled accurately.
The maintenance of small excavators is very important. Doing a good job in its maintenance can effectively improve work efficiency and increase revenue.
