1、电源的连接
1. Connection of power supply
先将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。
First, insert the three core plug of the host into the corresponding socket of the controller, and then connect the power line of the controller to the power grid. The green / yellow core wire is the grounding wire.
工作结束后，以相反方向拆卸。
After the work is finished, dismantle in the opposite direction.
2、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 support and tighten the screws. Start the main engine to make the square head pin hole correspond to the reaction support hole, then install the wrench socket, insert the pin, and fix it with 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, turn the positive and negative switch of the host to the forward rotation position, and put the wrench socket 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 to start the wrench. When the force arm of the reaction support is firmly against the fulcrum (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 will stop automatically and the tightening is completed. Release the power switch to tighten the next bolt.
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 arm of the bracket will automatically break away from the fulcrum by the elastic deformation force of the reaction support, and then the wrench can be removed. If the force arm can not be separated from the fulcrum, the positive and negative switch can be turned, and the power switch can be touched to remove the wrench.
3、螺栓的拆卸操作
3. Bolt removal
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 is removing the bolt (reversing), the operation method is the same as that of tightening, but the positive and negative switch is turned to the reverse position, and the power switch is not opened after the bolt is loosened.
