現如今受歡迎的電動扳手應用在諸多領域，不僅是汽車，連我們的日常生活也到處都需要緊固件的使用，而的電動扳手就需要利用它的優勢來為我們進行零件的加固，以防在未來的使用中發生特殊意外。那么使用電動扳手時又該注意哪些問題？

Nowadays, popular electric wrenches are used in many fields, not only in cars, but also in our daily lives where fasteners are needed. Professional electric wrenches need to use their advantages to reinforce our parts to prevent special accidents in future use. So what are the issues to pay attention to when using an electric wrench?

一、觸電問題

1、 Electric shock problem

1.使用前應該檢查電動扳手的內外零件是否完好，外殼和導線是否有絕緣效果，不允許有漏電現象；

1. Before use, check whether the internal and external parts of the electric wrench are intact, whether the shell and wires have insulation effect, and no leakage is allowed;

2.電動扳手所規定的電壓應該與運用的電壓相符合，且接地裝置必須正確，不可以將插頭插錯方向；

2. The voltage specified for the electric wrench should match the voltage used, and the grounding device must be correct. The plug should not be inserted in the wrong direction;

3.如果需要操作金屬容器，那么應該有專人在外面進行監護，而且漏電保護器與電源聯接器、操控箱都應該放在金屬容器的外面，操作人員應該踩在絕緣板上面進行操作，如果操作現場有濕潤的地方，那么應該要穿戴適宜的作業服，切記佩戴絕緣手套和鞋；

3. If it is necessary to operate a metal container, there should be a dedicated person outside for supervision, and the leakage protector, power connector, and control box should be placed outside the metal container. The operator should step on the insulation board for operation. If there is a damp area on the operation site, suitable work clothes should be worn, and insulated gloves and shoes should be worn;

4.如果操作現場無電源，需要進行延伸線纜，那么應該使用容量足夠的線纜，并安裝在高架上，防止線纜被碾壓損壞。

4. If there is no power supply at the operation site and extension cables are required, cables with sufficient capacity should be used and installed on an elevated platform to prevent cable damage caused by crushing.

二、機械損傷

2、 Mechanical damage

1.在進行替換扳頭時應該將電源插頭拔開，才可進行替換；

1. When replacing the trigger, the power plug should be unplugged before it can be replaced;

2.操作時應將扳手牢靠地固定住，防止東西抖動導致脫手，發生危險；

2. During operation, the wrench should be firmly fixed to prevent it from shaking and causing detachment, which could lead to danger;

3.在開機前應該學會判斷旋轉的方向，用力均勻；

3. Before starting up, you should learn to determine the direction of rotation and apply force evenly;

4.操作箱應該專人操作，所以作業時需要有兩個人進行互相配合；

4. The operation box should be operated by a dedicated person, so two people need to cooperate with each other during the operation;

5.使用電動扳手時身體應該有恰當的姿態，防止軸線與螺紋軸線無法對正。

When using an electric wrench, the body should have an appropriate posture to prevent misalignment between the axis and the threaded axis.
