2、工具使用的环境温度为-10℃-40℃，过高过低都会影响控制精度。

2. The environmental temperature of the tool is - 10 ℃ - 40 ℃, too high or too low will affect the control accuracy.
3、被拧螺栓的初始扭矩不得大于工具的额定扭矩的70%。螺栓达到额定扭矩后不得重拧。
3. The initial torque of the screwed bolt shall not be greater than 70% of the rated torque of the tool. The bolts shall not be re tightened after reaching the rated torque.
4、工具用于拆卸螺栓时，其扭矩不得大于额定扭矩值。一般情况下，不是本扳手拧紧的或锈蚀严重的螺栓，不宜用本扳手拆卸，以免造成工具损坏。
4. When the tool is used to remove the bolt, its torque shall not be greater than the rated torque value. Generally, bolts that are not tightened or seriously rusted by this wrench should not be removed by this wrench to avoid tool damage.
5、变换旋转方向时，必须待电机停止转动后进行，严禁在运转中拨动正反开关。
5. When changing the direction of rotation, it must be carried out after the motor stops rotating. It is strictly forbidden to move the positive and negative switches during operation.
6、当扳手自动停止后即可松开开关（如果不断开开关，过5秒钟扳手就会自行启动）待4-5秒后再进行开动扳手，否则扳手不能启动。
6. When the wrench stops automatically, the switch can be released (if the switch is opened continuously, the wrench will start automatically after 5 seconds) and the wrench can be started after 4-5 seconds, otherwise the wrench cannot be started.
