沖擊電動扳手主要是初緊螺栓的，它的使用很簡單，就是對準螺栓扳動電源開關就行。電動扭剪扳手主要是終緊扭剪型高強螺栓的，它的使用就是對準螺栓扳動電源開關，直到把扭剪型高強螺栓的梅花頭打斷為止。電動定扭矩扳手既可初緊又可終緊，它的使用是先調節(jié)扭矩，再緊固螺栓。電動轉角扳手主要也屬于定扭矩扳手的一種，它的使用是先調節(jié)旋轉度數(shù)，再緊固螺栓。電動角向扳手是一種專門緊固鋼架夾角部位螺栓的電動扳手，它的使用和電動扭剪扳手原理一樣。
The impact electric wrench is mainly used for initial tightening of bolts, and its use is very simple, which is to align the bolt and pull the power switch. The electric torque wrench is mainly used for final tightening of torque shear high-strength bolts. Its use is to align the bolt and pull the power switch until the plum blossom head of the torque shear high-strength bolt is broken. The electric fixed torque wrench can be used for both initial and final tightening. Its use involves adjusting the torque first and then tightening the bolts. Electric angle wrenches mainly belong to a type of fixed torque wrench, which is used to adjust the rotation degree first and then tighten the bolts. Electric angle wrench is a type of electric wrench specifically designed to tighten bolts at the angle of a steel frame, and its use is the same as that of an electric torsion wrench.
檢驗試驗及保養(yǎng)
Inspection, testing and maintenance
1、電動扳手的金屬外殼應可靠接地，其外殼應有定期檢驗試驗合格證，并在有效期限內(nèi)。
1. The metal shell of the electric wrench should be reliably grounded, and its shell should have a regular inspection and test certificate, which is within its validity period.
2、檢查電動扳手機身安裝螺釘緊固情況，若發(fā)現(xiàn)螺釘松了，應立即重新扭緊，否則會導致電動扳手故障。
2. Check the tightening of the installation screws on the body of the electric wrench. If the screws are found to be loose, they should be immediately re tightened, otherwise it may cause the electric wrench to malfunction.
3、檢查手持電動扳手兩側手柄完好，不開裂可破損，安裝牢固
3. Check that the handles on both sides of the handheld electric wrench are intact, not cracked or damaged, and installed firmly
注意事項
matters needing attention
1、確認現(xiàn)場所接電源與電動扳手銘牌是否相符。是否接有漏電保護器。
1. Confirm whether the on-site power supply matches the nameplate of the electric wrench. Is there a leakage protector connected.
2、根據(jù)螺帽大小選擇匹配的套筒，并妥善安裝。
2. Select a matching sleeve based on the size of the nut and install it properly.
3、在送電前確認電動扳手上開關斷開狀態(tài)，否則插頭插入電源插座時電動扳手將出其不意地立刻轉動，從而可能招致人員傷害危險。
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 unexpectedly turn immediately, which may cause a risk of personal injury.
4、若作業(yè)場所在遠離電源的地點，需延伸線纜時，應使用容量足夠，安裝合格的延伸線纜。延伸線纜如通過人行過道應高架或做好防止線纜被碾壓損壞的措施。
4. If the workplace is located far away from the power source and it is necessary to extend the cable, a qualified extension cable with sufficient capacity should be used and installed. If the extension cable passes through a pedestrian walkway, it should be elevated or measures should be taken to prevent the cable from being crushed and damaged.
5、盡可能在使用時找好反向力距支靠點，以防反作用力傷人。
5. Try to find a good support point for the reverse force distance during use to prevent injury caused by the reverse force.
6、使用時發(fā)現(xiàn)電動機碳火花異常時，應立即停止工作，進行檢查處理，排除故障。此外碳刷必須保持清潔干凈。
6. When abnormal carbon sparks are found during use, the motor should be immediately stopped for inspection and troubleshooting. In addition, the carbon brush must be kept clean.
7、站在梯子上工作或高處作業(yè)應做好高處墜落措施，梯子應有地面人員扶持。
7. Standing on a ladder or working at heights, measures should be taken for falling from height, and the ladder should be supported by ground personnel.
