折弯长或大工件时，需要两人以上协同工作。避免由于工件受力变形时倾倒。不

When bending long or large workpieces, two or more people are required to work together. <br>Avoid tipping when the workpiece is deformed by force. <br>It is not allowed to hold the pressed workpiece at close range. <br>When calibrating or pressing the workpiece, the operator should place the workpiece in the middle of the mold without biasing. <br>The upper die should approach the workpiece slowly to prevent the workpiece from being forced out. <br>It is necessary to check whether the strokes of the two cylinders are consistent during work. If you encounter any problems, please adjust or report for repair in time. <br>When the oil cylinder piston is shaken or the oil pump makes noise, the air in the oil circuit must be discharged. <br>Always pay attention to the fuel tank and observe whether the oil level is suitable. <br>If the oil level is too high, check the oil return line and adjust the oil return valve. It is strictly forbidden to overflow the fuel tank. Keep working oil temperature ≤45℃.

When bending long or large work pieces, more than two people are required to work together.<br>Avoid dumping when deformed due to force on the work piece.<br>Do not hand the pressed work pieces up close.<br>When correcting or pressing the work piece, the operator should place the work piece in the middle of the mold and not allow bias.<br>The upper mold should slowly approach the work piece to prevent the work piece from being forced out.<br>The travel of the two cylinders needs to be checked frequently during work. If you encounter problems, please adjust or report them in time.<br>Air in the oil path must be drained when cylinder piston shakes or when noise from the oil pump is detected.<br>Always pay attention to the tank and observe if the oil surface is suitable.<br>If the oil surface is too high, check the return line and adjust the return valve. Do not spill the fuel tank. Keep the operating oil temperature ≤ 45 degrees C.
