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(yàn)試驗(yàn)及保養(yǎng)

Inspection, testing and maintenance

1、電動(dòng)扳手的金屬外殼應(yīng)可靠接地，其外殼應(yīng)有定期檢驗(yàn)試驗(yàn)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(dòng)扳手機(jī)身安裝螺釘緊固情況，若發(fā)現(xiàn)螺釘松了，應(yīng)立即重新扭緊，否則會(huì)導(dǎo)致電動(dòng)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(dòng)扳手兩側(cè)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(xiàng)

matters needing attention

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 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(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 unexpectedly turn immediately, which may cause a risk of 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 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(shí)找好反向力距支靠點(diǎn)，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(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(yīng)做好高處墜落措施，梯子應(yīng)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.
