When crushing particularly hard objects, start from the edge, and do not knock continuously for granite crushing production line more than 1min at the same point to prevent the brazing rod from burning down or the hydraulic oil from overheating.

Do not use the retaining plate of the broken hammer as a tool to push the weight. Because the excavating loader is mainly a small machine, its own weight is light, if it pushes the weight, it will damage the granite crushing produciton line, which will cause the main engine lifting arm to break seriously, and even cause the main engine turning over accident.

Operate when the hydraulic cylinder is fully extended or fully shrunk; otherwise, the impact vibration will be transmitted to the hydraulic cylinder body and then to the main engine.
