一、电源的连接
I. Connection of Power Supply
先将定扭矩扳手主机的三芯插头插入控制仪相应的插座上，然后将控制仪上的电源线接入电网。绿/黄双色芯线为接地线。工作结束后，以相反方向拆卸。
Firstly, the three-core plug of the main engine of the fixed torque wrench is inserted into the corresponding socket of the controller, and then the power line of the controller is connected to the power grid. Green/yellow dual-color core wire is grounding wire. After work, disassemble in the opposite direction.
二、螺栓的扭紧操作
2. Tightening operation of bolts
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 fasten the screw. Start the main engine, so that the square head pin hole corresponds to the counterforce support hole, and then install the pulling glove barrel, insert the pin, and fix it with the rubber ring.
2、将控制仪的扭矩旋扭调到所需扭矩值，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 of the controller to the required torque value, set the positive and negative switch of the main engine to the positive rotation position, and put the wrench glove barrel on the hexagon of the threaded connector.
3、按下电源开关，扳手启动。当反力支架力臂靠牢支点时（支点可以是邻近的一只螺栓或其他可做支点的位置）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，放开电源开关，进行下一只螺栓的紧固工作。
3. Press the power switch and start the wrench. When the reaction bracket arm is firmly supported (the fulcrum can be a nearby bolt or other fulcrum position), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench automatically stops and tightens, releases the power switch, and tightens the next bolt.
4、定扭矩扳手自动停止后，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 fixed-torque wrench stops automatically, the elastic deformation force of the reaction bracket makes the bracket arm automatically detach from the fulcrum and take down the wrench. If the force arm can not be separated from the fulcrum, the positive and negative switch can be switched, the power switch can be activated, and the wrench can be removed.
三、螺栓的拆卸操作
3. Bolt disassembly operation
扳手在拆卸螺栓（反转）时，其操作方法与拧紧操作相同，只是将正反开关拨到反转位置，螺栓卸松后防开电源开关。
When the wrench disassembles the bolt (inversion), its operation method is the same as the tightening operation, only the positive and negative switch is moved to the inversion position, and the power switch is prevented after the bolt is released.
