Briefly describe the operation method of hydraulic wrench

After confirming that the basic parts of the hydraulic wrench are normal, you also need to make sure that: there is no one in front of the bolt to be tightened; any part of your body does not target the bolt to be tightened before you can operate.
When using a hydraulic wrench, two people should be arranged to operate together: one to operate the wrench and the other to operate the hydraulic pump. And the operation of the hydraulic wrench is carried out by the wrench holder. When the hydraulic pump starts to work, the operator must always observe and pay attention to the value of the pressure gauge of the hydraulic pump. If the value exceeds the normal range, it must stop using it immediately and report for repair in time.
When using a hydraulic wrench, it must be placed on a fixed surface. After finding a stable fulcrum, reconfirm whether there is oil in the oil tank of the hydraulic pump and whether the oil pipe is unobstructed without being squeezed and blocked by obstructions. After all these are no problems, we can start the hydraulic wrench. If the hydraulic wrench trembles significantly, then we must immediately stop pressurizing and readjust the fixed position and support point of the hydraulic wrench. In addition, avoid excessive bending of the high-pressure tubing during use to prevent the formation of backup pressure in the tubing, which will reduce the life of the tubing.
Since different bolt types correspond to different hydraulic wrenches, in the process of use, you must not use small wrenches instead of large wrenches to work. For the sake of convenience, use hydraulic wrenches that do not match the nut specifications to forcibly split or tighten the nuts.
