操作人员应了解定扭矩电动扳手的结构，原理，性能和使用，并达到会操作，会维护和会故障排除的“四懂三会”的标准。
Operators should understand the structure, principle, performance, and use of fixed torque electric wrenches, and meet the standards of "four understandings and three abilities" in operation, maintenance, and troubleshooting.
连接电源之前，请检查电源电压是否与定扭矩电动扳手的铭牌相匹配，以及是否连接了漏电保护器。
Before connecting to the power supply, please check whether the power voltage matches the nameplate of the fixed torque electric wrench and whether a leakage protector is connected.
定扭矩电动扳手的环境温度为-10°C?40°C，当环境温度超过此范围时，请勿使用电动扳手。 如果确实需要使用它，则应在相同的温度条件下标定，并对该扳手所施拧的螺栓全部进行扭矩检查。 请勿在潮湿或多雨的环境中使用，以免漏电。
The ambient temperature for a fixed torque electric wrench is -10 ° C? Do not use an electric wrench when the ambient temperature exceeds 40 ° C. If it is indeed necessary to use it, it should be calibrated under the same temperature conditions and all bolts tightened by the wrench should be torque checked. Do not use in damp or rainy environments to avoid electrical leakage.
工作之前，应先打开定扭矩电动扳手并使其空转3?5分钟。 在操作过程中，如果电动机火花大，声音异常，转矩不稳定等，应立即将其关闭进行检查。 使用时请尽量找到反向力矩支靠点，以防止反作用力伤害人。
Before working, the fixed torque electric wrench should be opened and allowed to idle for 3 seconds? 5 minutes. During operation, if the motor has a large spark, abnormal sound, unstable torque, etc., it should be immediately turned off for inspection. When using, please try to find the support point for the reverse torque to prevent the reaction force from harming people.
改变旋转方向时，必须在电动机停止转动后进行。 严格禁止在定扭矩电动扳手操作过程中拨动正反转开关。
When changing the direction of rotation, it must be done after the motor stops rotating. It is strictly prohibited to toggle the forward and reverse switches during the operation of a fixed torque electric wrench.
被拧螺栓的初拧扭矩应不大于电动扳手额定扭矩的70％。 当被拧螺栓达到规定的扭矩时，不得对该螺栓重复施拧。
The initial tightening torque of the tightened bolt should not exceed 70% of the rated torque of the electric wrench. When the tightened bolt reaches the specified torque, it is not allowed to repeatedly tighten the bolt.
当扳手自动停止时，请立即松开开关（如果未及时关闭开关，扳手将在5秒钟后自动启动，这将导致螺丝拧得过紧。 如果需要再次启动扳手，请等待45秒钟，否则无法启动扳手。
When the wrench automatically stops, please immediately release the switch (if the switch is not closed in a timely manner, the wrench will automatically start after 5 seconds, which will cause the screws to be tightened too tightly. If you need to start the wrench again, please wait for 4 to 5 seconds, otherwise the wrench cannot be started.
定扭矩电动扳手自动停止后，如果无法平稳地卸下扳手，则可以拨动正反转开关，点动电源开关扳手即可取下。
After the fixed torque electric wrench automatically stops, if it is not possible to smoothly remove the wrench, you can turn the forward and reverse switches and click the power switch wrench to remove it.
搬运时不可提拉电缆线，并注意轻拿轻放，以防振动和摔碰。 不使用时，应将其放在通风干燥的地方，不要与酸，碱和其他有害物质接触或一起存放。
Do not lift or pull cables during transportation, and be careful to handle them gently to prevent vibration and falling. When not in use, it should be placed in a well ventilated and dry place, and should not come into contact with acids, alkalis, and other harmful substances or be stored together.
每工作100个小时，应对碳刷、齿轮等部位进行检查和保养。
Every 100 working hours, carbon brushes, gears, and other parts should be inspected and maintained.
