作业前，仔细查看液压剪板机控制组织是不是灵敏、可靠、保证没有松动。空载

Before the job, look carefully controlled hydraulic shears organization is not sensitive and reliable, to ensure that no loose. No-load test machine is not working properly; if there is a slider or even the red hysteresis phenomenon; safety equipment is not intact and useful.

Before the job, carefully check the hydraulic shear machine control organization is not sensitive, reliable, to ensure that there is no loose. The job of the empty experimental machine is not normal, the slider is delayed or continuous, and the safety equipment is not available and useful.

Before operation, carefully check whether the control organization of the hydraulic shearing machine is sensitive, reliable and free from looseness. Whether the operation of the no-load experimental machine is normal; whether the slide block has hysteresis or continuous impact; whether the safety equipment is intact and useful.<br>
