At the construction site, the manhole cover rounding machine occasionally has various faults. Some of these failures are due to product quality, but most of them are caused by improper use. Therefore, we must strictly follow the operating procedures for construction. First of all, if the brakes fail, the first task is to check whether the friction pads are damaged. If the friction plate is damaged, it must be replaced immediately, and there is no chance of leaving it to chance. Otherwise, in the event of an accident, it may lead to injury to the person.
Secondly, if we find that the cutting line deviates, the steering is slow or does not move during the construction process, we need to check whether the cutting disc is broken, and whether the buffer valve spring has debris. Once the cutting disc is damaged, it should be replaced in time. If there is debris in the spring in the snubber valve, the spring needs to be replaced and the debris removed. Be sure to cut off the power to the device before making a replacement. Furthermore, if there is a lot of resistance or difficulty in rotating when turning the direction, we need to check whether the dial is broken, deformed or worn, and whether the transmission linkage shaft is worn or deformed. As soon as the above situation is discovered, the dial and drive linkage shaft should be replaced immediately, and the transmission oil should be injected. 
Finally, if there is slippage during the cutting process, check whether there is dust or oil on the cutting disc. These stains can cause the manhole cover rounding machine to slip sideways. When encountering a manhole cover rounding machine failure, there is no need to panic. As long as we maintain the correct way of operation in daily use and increase the coping method, we can reduce unnecessary failures and make the work easier!
The specifications and models of the manhole cover cutting machine are mainly hand-pushed and fully automatic, and we choose a cost-effective one according to the needs of the work, and choose a cost-effective one under the premise of quality assurance.
