1、扭剪螺栓裝上反力支架，并緊固螺釘。開動主機，使方頭銷孔與反力支架孔相對應，然后裝入扳手套筒，插上銷釘，并用橡膠圈固定。
1. Install the reaction support with torsion shear bolts and tighten the screws. Start the main engine so that the square head pin hole corresponds to the reaction support hole, then install the wrench socket, insert the pin and fix it with a rubber ring.
2、將控制儀的扭矩旋鈕調(diào)到所需扭矩值，扭剪螺栓將主機正反開關撥到正轉(zhuǎn)位置，把扳手套筒套在螺紋連接件的六方上。
2. Adjust the torque knob of the controller to the required torque value, twist the shear bolt, turn the forward and reverse switch of the main engine to the forward position, and put the wrench socket on the hexagon of the threaded connector.
3、扭剪螺栓按下電源開關，扳手啟動。當反力支架力臂靠牢支架時(支點可以是鄰近的一只螺栓或其他可作支點的位置)螺栓開始擰緊。當螺栓扭矩達到預定扭矩時，扳手自動停止，緊固完成，松開電源開關，進行下一只螺栓的擰緊工作。
3. Twist the shear bolt, press the power switch and start the wrench. When the force arm of the reaction support is firmly against the support (the fulcrum can be an adjacent bolt or other position that can be used as a fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench will automatically stop, the tightening is completed, loosen the power switch and tighten the next bolt.
4、扭剪螺栓扳手自動停止后，靠反力支架的彈性形變力，使支架力臂自動脫離支點，取下扳手。如力臂不能脫離支點時，可撥動正反開關，點動電源開關扳手即可取下。
4. After the torsion shear bolt wrench stops automatically, the force arm of the support is automatically separated from the fulcrum by the elastic deformation force of the reaction support, and the wrench is removed. If the force arm cannot be separated from the fulcrum, turn the positive and negative switch and click the power switch wrench to remove it.
