3.在更換扳頭時必須將電源插頭拔開后才能進行更換。
3. When replacing the wrench head, the power plug must be unplugged before replacement.
4.使用時必須將扳手可靠的固定住，雙手必須把牢(特殊情況下可把扳手吊起固定好)，防止工具擅動脫手發生危險。
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.開機前必須確定旋轉方向，確定無異常后再進行工作，工作時用力應均勻，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.工作時必須2人以上，專人對操作箱進行操作，控制電動扳手的工作與停止。
6. More than 2 people must be assigned to operate the operation box and control the operation and stop of the electric wrench.
7.使用時應扶正扳手，要避免碰掉扳頭，嚴防電纜帶電脫落。
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.工作時身體必須保持適當的正確姿勢，必須站穩，使工具軸線與螺紋軸線對正、握穩。
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.接通電源前必須認真檢查所使用工具的開關應處在關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.所使用工具在關閉開關后必須待機器完全停止后才能將其放在可靠的位置上，然后拔下插頭。
