5. operation method of this machine tool: function of bolt cutter: when driving, supporting and repairing coal mine roadways

a. divide AK by the thickness of the cross-sectional area f at the specimen notch according to the shear material, and adjust the clearance of the blade

b. adjust the profiling or fixture according to the width of the sheared material

c. before the operation of the machine tool, first make 1 or 3 times of empty travel, and then implement the cutting work after it is normal
