1. Electrical failure, 2 ~ 3 stroke switches are usually arranged behind the cutter's transmission mechanism (turbine box, gear transmission, etc.), one is mainly used after the cutter is too low, when both hands leave the button, the cutter will Automatically return to the high point (considering the cutter counting function); the other one is used for the high point stop model. When the position of the travel switch and the bumper is incorrect, the cutter will not stop at the high point (in this case only Need to adjust the position of the bumper or the travel switch to remove the fault.
        2. Brake failure, there must be a brake device at the input end of the cutter transmission device (turbine box, gear transmission, etc.). When the brake pad is worn or the gap is too large, the cutter cannot stop at a high point (adjust the gap or replace the brake pad) It can be solved), or the clutch disc is stuck, which makes the return position inflexible (disassemble the brake parts, clean and add oil to solve)

        3. Hydraulic failure, when the new machine leaves the factory, the hydraulic piston does not return to the low point. After a period of use, the piston returns to the low point after the surface is worn in, causing the position of the paper press to be too high (generally the blade is lower than the bottom of the paper press ), This simple method of handling is that most manufacturers will set a top cover on the piston head, we only need to thicken the top cover to solve. The approximate parameter is that when the top cover is thickened by 1mm, the paper presser is lowered by about 1.4mm.
