4. Before use, qualified leakage protectors with rated action current not greater than 15mA and action time not greater than 0.1s or rated leakage action current not greater than 30mA and action time not greater than 0.1s shall be installed according to different types of tools used.
5.在金屬容器內(nèi)工作時(shí)，建議設(shè)專人在外不間斷地監(jiān)護(hù)，漏電保護(hù)器、電源聯(lián)接器和控制箱應(yīng)放在容器外面，工作人員腳下應(yīng)墊上絕緣板，在非常潮濕的地方使用電動(dòng)工具建議穿戴合適的工作服、配戴絕緣手套和絕緣鞋。
5. When working in metal containers, special personnel must be assigned to continuously monitor outside. Leakage protectors, power connectors and control boxes should be placed outside the containers. Insulating plates should be placed under the feet of workers. When using electric tools in particularly humid places, appropriate work clothes, insulating gloves and insulating shoes must be worn.
二、機(jī)械傷害：
2、 Mechanical injury:
1.使用前建議確認(rèn)該扳手為合格扳手，貼有標(biāo)簽或有合格證。
1. Before use, it must be confirmed that the wrench is qualified, with label or certificate.
2.使用前建議檢查機(jī)械傳動(dòng)部分各部螺母緊固牢靠，合格后才能使用。
2. Before use, check that the nuts of all parts of the mechanical transmission part are fastened firmly and can be used only after they are qualified.
3.在更換扳頭時(shí)建議將電源插頭拔開后才能進(jìn)行更換。
3. When replacing the wrench head, the power plug must be unplugged before replacement.
4.使用時(shí)建議將扳手可靠的固定住，雙手建議把牢(特殊情況下可把扳手吊起固定好)，防止工具擅動(dòng)脫手發(fā)生危險(xiǎn)。
4. When using, the wrench must be reliably fixed, and both hands must be firmly held (the wrench can be lifted and fixed under special circumstances) to prevent the danger of tools moving without permission.
5.開機(jī)前建議確定旋轉(zhuǎn)方向，確定無異常后再進(jìn)行工作，工作時(shí)用力應(yīng)均勻，禁止用力過猛。
5. The rotation direction must be determined before starting the machine, and the work can be carried out after it is confirmed that there is no abnormality. The force shall be uniform during work, and excessive force is prohibited.
6.工作時(shí)建議2人以上，專人對(duì)操作箱進(jìn)行操作，控制電動(dòng)扳手的工作與停止。
6. More than 2 people must be assigned to operate the operation box and control the operation and stop of the electric wrench.
7.使用時(shí)應(yīng)扶正扳手，要避免碰掉扳頭，嚴(yán)防電纜帶電脫落。
7. When using, the wrench shall be righted to avoid touching the wrench head and strictly prevent the cable from falling off with electricity.
8.工作時(shí)身體建議保持適當(dāng)?shù)恼_姿勢(shì)，建議站穩(wěn)，使工具軸線與螺紋軸線對(duì)正、握穩(wěn)。
8. When working, the body must maintain a proper and correct posture, and must stand firmly to align and hold the tool axis with the thread axis.
9.接通電源前建議認(rèn)真檢查所使用工具的開關(guān)應(yīng)處在關(guān)閉位置后才能接通電源。
9. Before connecting the power supply, carefully check that the switch of the tool used should be in the off position before connecting the power supply.
10.所使用工具在關(guān)閉開關(guān)后建議待機(jī)器完全停止后才能將其放在安全可靠的位置上，然后拔下插頭。
10. After closing the switch, the tools used can only be placed in a safe and reliable position after the machine is completely stopped, and then pull out the plug.
