定扭矩电动扳手东西运用的环境温度为零下十度到零下四十度，当温度过高过低的时候都会影响控制点精度的。
The ambient temperature of the fixed torque electric wrench is from minus 10 degrees to minus 40 degrees. When the temperature is too high or too low, the precision of the control point will be affected.
另外的扳手的被拧螺栓的开始的扭矩好不要大于扭矩的百分之七十，螺栓到达额定扭矩后不得重拧。改换旋转方向时，有必要待电机间断翻滚后进行，禁止在工作中拨动正反开关。
In addition, the initial torque of the screwed bolt of the wrench should not be greater than 70% of the torque, and the bolt should not be re-twisted after reaching the rated torque. When changing the direction of rotation, it is necessary to wait for the motor to roll intermittently. It is forbidden to turn the positive and negative switches in the work.
电动扳手用于拆开螺栓的时候，它的扭矩一般不能大于额定值。通常情况下，如果扳手不是没京津活着生锈的话，一般是不建议大家拆开的，否则容易不好用或者损坏。
When the electric wrench is used to remove the bolt, its torque can not be greater than the rated value. Usually, if the wrench is not rusty without Beijing and Tianjin, it is generally not recommended that you open it, otherwise it is easy to be difficult to use or damaged.
还有就是当我们接通电源前需要先检查一下电影是不是和设备的是一致的，有没有接地装置。避免造成不良的事故。
Also, before we turn on the power supply, we need to check whether the movie is consistent with the equipment and whether there is a grounding device. Avoid causing bad accidents.
当我们在使用扳手的自动间断后我们就可以断开，等待四到五秒后我们在开动扳手就行，要不扳手是不能发动的。
When we use the automatic interruption of the wrench, we can disconnect. Wait four to five seconds before we start the wrench, otherwise the wrench can not start.
