What should I do if the small excavator cannot rotate?
1. Hydraulic system failure
The main reason why the small excavator cannot rotate may be a failure of the hydraulic system, resulting in insufficient oil pressure or insufficient flow, making it impossible to control the smooth rotation of the hydraulic cylinder. At this time, you need to check whether the oil pressure and flow of the hydraulic system are normal. If they are insufficient, you need to add oil or replace the oil. At the same time, it is necessary to check whether the hydraulic system pipelines are clear to prevent pipeline blockage and insufficient flow. In addition, it is also necessary to check whether the valves of the hydraulic system are normal. If they are damaged, they need to be replaced in time.
2. Electrical system problems
Another possible reason why a small excavator cannot rotate is an electrical system problem, such as aging wires or loose connections leading to a blocked circuit. In this case, you need to check whether the wire connections in the electrical system are loose or the wires are aged or damaged. At the same time, check whether the solenoid valve is normal and eliminate electrical system problems to avoid affecting the rotation of the small excavator.
3. Other reasons
In addition to hydraulic system failures and electrical system problems, there may also be other reasons why the small excavator cannot rotate, such as mechanical failure, causing the rotating part to become stuck or damaged, requiring mechanical repair or replacement. In addition, you also need to check whether the lubricating oil of the small excavator is sufficient and whether it needs to be replaced, and clean the debris and dust on the surface of the machine to keep the machine in good working condition.
In short, when the small excavator cannot rotate, problems with the hydraulic system and electrical system need to be eliminated first. If the problem still exists, you can check whether the mechanical parts and lubricating oil are normal, and perform timely maintenance and repairs to ensure the normal use of the small excavator.
