1、确认现场所接电源与电动扳手铭牌是否相符。是否接有漏电保护器。
1. Confirm whether the on-site power supply is consistent with the nameplate of the electric wrench. Whether leakage protector is connected.
2、根据螺帽大小选择匹配的套筒，并妥善安装。
2. Select the matching sleeve according to the size of the nut and install it properly.
3、在送电前确认电动扳手上开关断开状态，否则插头插入电源插座时电动扳手将出其不意地立刻转动，从而可能招致人员伤害危险。
3. Before power transmission, confirm that the switch on the electric wrench is disconnected, otherwise when the plug is inserted into the power socket, the electric wrench will turn unexpectedly immediately, which may cause personal injury.
4、若作业场所在远离电源的地点，需延伸线缆时，应使用容量足够，安装合格的延伸线缆。延伸线缆如通过人行过道应高架或做好防止线缆被碾压损坏的措施。
4. If the workplace is far away from the power supply and it is necessary to extend the cable, use the extension cable with sufficient capacity and install the qualified extension cable. If the extension cable passes through the pedestrian aisle, it shall be elevated or measures shall be taken to prevent the cable from being crushed and damaged.
5、尽可能在使用时找好反向力距支靠点，以防反作用力伤人。
5. Try to find the supporting point of the reverse force distance during use to prevent the reaction force from hurting people.
6、使用时发现电动机碳火花异常时，应立即停止工作，进行检查处理，排除故障。此外一定要保持清洁干净。
6. In case of abnormal carbon spark of the motor during use, stop working immediately, check and deal with it and eliminate the fault. In addition, be sure to keep it clean.
7、站在梯子上工作或高处作业应做好高处坠落措施，梯子应有地面人员扶持。
7. Measures for falling from height shall be taken when working on a ladder or working at heights, and the ladder shall be supported by ground personnel.
8、冲击电动扳手主要是初紧螺栓的，它的使用很简单，就是对准螺栓扳动电源开关就行。电动扭剪扳手主要是终紧扭剪型高强螺栓的，它的使用就是对准螺栓扳动电源开关，直到把扭剪型高强螺栓的梅花头打断为止。电动定扭矩扳手既可初紧又可终紧，它的使用是先调节扭矩，再紧固螺栓。电动转角扳手主要也属于定扭矩扳手的一种，它的使用是先调节旋转度数，再紧固螺栓。电动角向扳手是一种专门紧固钢架夹角部位螺栓的电动扳手，它的使用和电动扭剪扳手原理一样。
8. The impact electric wrench is mainly used to initially tighten the bolt. Its use is very simple. Just aim at the bolt and pull the power switch. The electric torsion shear wrench is mainly used to finally tighten the torsion shear high-strength bolt. Its use is to align the bolt and pull the power switch until the plum blossom head of the torsion shear high-strength bolt is broken. The electric constant torque wrench can be tightened initially and finally. Its use is to adjust the torque first and then tighten the bolts. Electric angle wrench mainly belongs to a kind of constant torque wrench. Its use is to adjust the rotation degree first, and then tighten the bolt. The electric angle wrench is an electric wrench specially used to fasten the bolts at the included angle of the steel frame. Its use principle is the same as that of the electric torsion shear wrench.
