1、装上反力支架，并紧固螺钉。开动主机，使方头销孔与反力支架孔相对应，然后装入扳手套筒，插上销钉，并用橡胶圈固定。

1. Install the reaction bracket and tighten the screws. Start the host, align the square pin hole with the reaction bracket hole, then install the wrench socket, insert the pin, and fix it with a rubber ring.

2、将控制仪的扭矩旋钮调到所需扭矩值，将主机正反开关拨到正转位置，把扳手套筒套在螺纹连接件的六方上。

2. Adjust the torque knob of the controller to the desired torque value, turn the positive and negative switches of the host to the positive rotation position, and insert the wrench socket onto the hexagonal threaded connector.

3、按下电源开关，扳手启动。当反力支架力臂靠牢支架时（支点可以是邻近的一只螺栓或其他可作支点的位置）螺栓开始拧紧。当螺栓扭矩达到预定扭矩时，扳手自动停止，紧固完成，松开电源开关，进行下一只螺栓的拧紧工作。

3. Press the power switch to activate the wrench. When the force arm of the reaction bracket is firmly attached to the bracket (the fulcrum can be an adjacent bolt or other position that can serve as a fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench automatically stops, the tightening is completed, the power switch is released, and the next bolt tightening work is carried out.

4、扳手自动停止后，靠反力支架的弹性形变力，使支架力臂自动脱离支点，取下扳手。如力臂不能脱离支点时，可拨动正反开关，点动电源开关扳手即可取下。

4. After the wrench stops automatically, the elastic deformation force of the reaction bracket causes the bracket arm to automatically detach from the fulcrum and remove the wrench. If the lever arm cannot detach from the pivot point, the forward and reverse switches can be turned, and the power switch wrench can be used to remove it.
