1、確認(rèn)現(xiàn)場(chǎng)所接電源與電動(dòng)扳手銘牌是否相符。是否接有漏電保護(hù)器。
1. Confirm whether the on-site power supply is consistent with the nameplate of the electric wrench. Whether leakage protector is connected.
2、根據(jù)螺帽大小選擇匹配的套筒，并妥善安裝。
2. Select the matching sleeve according to the size of the nut and install it properly.
3、在送電前確認(rèn)電動(dòng)扳手上開關(guān)斷開狀態(tài)，否則插頭插入電源插座時(shí)電動(dòng)扳手將出其不意地立刻轉(zhuǎn)動(dòng)，從而可能招致人員傷害危險(xiǎn)。
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、若作業(yè)場(chǎng)所在遠(yuǎn)離電源的地點(diǎn)，需延伸線纜時(shí)，應(yīng)使用容量足夠，安裝合格的延伸線纜。延伸線纜如通過人行過道應(yīng)高架或做好防止線纜被碾壓損壞的措施。
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、盡可能在使用時(shí)找好反向力距支靠點(diǎn)，以防反作用力傷人。
5. Try to find the supporting point of the reverse force distance during use to prevent the reaction force from hurting people.
6、使用時(shí)發(fā)現(xiàn)電動(dòng)機(jī)碳火花異常時(shí)，應(yīng)立即停止工作，進(jìn)行檢查處理，排除故障。此外一定要保持清潔干凈。
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處作業(yè)應(yīng)做好高處墜落措施，梯子應(yīng)有地面人員扶持。
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、沖擊電動(dòng)扳手主要是初緊螺栓的，它的使用很簡(jiǎn)單，就是對(duì)準(zhǔn)螺栓扳動(dòng)電源開關(guān)就行。電動(dòng)扭剪扳手主要是終緊扭剪型高強(qiáng)螺栓的，它的使用就是對(duì)準(zhǔn)螺栓扳動(dòng)電源開關(guān)，直到把扭剪型高強(qiáng)螺栓的梅花頭打斷為止。電動(dòng)定扭矩扳手既可初緊又可終緊，它的使用是先調(diào)節(jié)扭矩，再緊固螺栓。電動(dòng)轉(zhuǎn)角扳手主要也屬于定扭矩扳手的一種，它的使用是先調(diào)節(jié)旋轉(zhuǎn)度數(shù)，再緊固螺栓。電動(dòng)角向扳手是一種專門緊固鋼架夾角部位螺栓的電動(dòng)扳手，它的使用和電動(dòng)扭剪扳手原理一樣。
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.
The above is a detailed introduction to the electric wrench for torsion and shear. I hope it will be helpful to you If you have any questions, please contact us We will provide service for you with professional attitude http://www.8ying.cn
