操作人員應了解定扭矩電動扳手的結(jié)構(gòu)，原理，性能和使用，并達到會操作，會維護和會故障排除的“四懂三會”的標準。
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.
連接電源之前，請檢查電源電壓是否與定扭矩電動扳手的銘牌相匹配，以及是否連接了漏電保護器。
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.
定扭矩電動扳手的環(huán)境溫度為-10°C?40°C，當環(huán)境溫度超過此范圍時，請勿使用電動扳手。 如果確實需要使用它，則應在相同的溫度條件下標定，并對該扳手所施擰的螺栓全部進行扭矩檢查。 請勿在潮濕或多雨的環(huán)境中使用，以免漏電。
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，應先打開定扭矩電動扳手并使其空轉(zhuǎn)3?5分鐘。 在操作過程中，如果電動機火花大，聲音異常，轉(zhuǎn)矩不穩(wěn)定等，應立即將其關閉進行檢查。 使用時請盡量找到反向力矩支靠點，以防止反作用力傷害人。
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.
改變旋轉(zhuǎn)方向時，必須在電動機停止轉(zhuǎn)動后進行。 嚴格禁止在定扭矩電動扳手操作過程中撥動正反轉(zhuǎn)開關。
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.
被擰螺栓的初擰扭矩應不大于電動扳手額定扭矩的70％。 當被擰螺栓達到規(guī)定的扭矩時，不得對該螺栓重復施擰。
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.
當扳手自動停止時，請立即松開開關（如果未及時關閉開關，扳手將在5秒鐘后自動啟動，這將導致螺絲擰得過緊。 如果需要再次啟動扳手，請等待45秒鐘，否則無法啟動扳手。
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.
定扭矩電動扳手自動停止后，如果無法平穩(wěn)地卸下扳手，則可以撥動正反轉(zhuǎn)開關，點動電源開關扳手即可取下。
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.
搬運時不可提拉電纜線，并注意輕拿輕放，以防振動和摔碰。 不使用時，應將其放在通風干燥的地方，不要與酸，堿和其他有害物質(zhì)接觸或一起存放。
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個小時，應對碳刷、齒輪等部位進行檢查和保養(yǎng)。
Every 100 working hours, carbon brushes, gears, and other parts should be inspected and maintained.
