1、接通電源前應先查看電源電壓是否與本產品銘牌相符，是否有接地裝置。當電源電壓超出+10%時應采取穩壓措施，否則會影響控制精度。接地不良易造成事故。
1. Before connecting the power supply, check whether the power supply voltage is consistent with the nameplate of the product and whether there is a grounding device. When the power supply voltage exceeds + 10%, voltage stabilizing measures shall be taken, otherwise the control accuracy will be affected. Poor grounding is easy to cause accidents.
2、工具使用的環境溫度為-10℃-40℃，過高過低都會影響控制精度。
2. The ambient temperature of the tool is - 10 ℃ - 40 ℃, too high or too low will affect the control accuracy.
3、被擰螺栓的初始扭矩不得大于工具的額定扭矩的70%。螺栓達到額定扭矩后不得重擰。
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、工具用于拆卸螺栓時，其扭矩不得大于額定扭矩值。一般情況下，不是本扳手擰緊的或銹蝕嚴重的螺栓，不宜用本扳手拆卸，以免造成工具損壞。
4. When the tool is used to remove the bolt, its torque shall not be greater than the rated torque. Generally, the bolts that are not tightened or seriously rusted by this wrench should not be removed with this wrench to avoid tool damage.
5、變換旋轉方向時，必須待電機停止轉動后進行，嚴禁在運轉中撥動正反開關。
5. When changing the rotation direction, it must be carried out after the motor stops rotating. It is strictly prohibited to toggle the positive and negative switches during operation.
6、當扳手自動停止后即可松開開關（如果不斷開開關，過5秒鐘扳手就會自行啟動）待4-5秒后再進行開動扳手，否則扳手不能啟動。
6. When the wrench stops automatically, loosen the switch (if the switch is not opened, the wrench will start automatically after 5 seconds). Start the wrench after 4-5 seconds, otherwise the wrench cannot start.
定扭矩電動扳手操作注意事項
Precautions for operation of constant torque electric wrench
1、螺栓直徑的大小對控制精度有一定的影響，施工中應用相同型號的螺栓連接付來標定扭矩值，而且使用一段時間后還應進行檢驗校定。
1. The size of bolt diameter has a certain impact on the control accuracy. During construction, the same type of bolt connection pair shall be used to calibrate the torque value, and inspection and calibration shall be carried out after use for a period of time.
2、工作前應開機空轉3-5分鐘。操作中如發現電機火花大，聲音異常，扭矩不穩定時，應立即停機檢查，切勿帶病工作。
2. Start up and idle for 3-5 minutes before operation. In case of large spark, abnormal sound and unstable torque of the motor during operation, stop the machine immediately for inspection and do not work with disease.
3、定期清洗和更換油脂，一般在工作5000次后，應進行***清洗加油，以延長使用壽命。
3. Clean and replace the grease regularly. Generally, after 5000 times of operation, * * * cleaning and refueling shall be carried out to prolong the service life.
4、主機上的電源開關，碳刷，控制儀上的保險絲等均屬易損件，容易引起故障，應經常檢查，及時更換。
4. The power switch, carbon brush and fuse on the control instrument on the host are vulnerable parts, which are easy to cause faults. They should be checked frequently and replaced in time.
5、使用中如發現工具上的螺釘松動，應及時緊固。
5. If the screw on the tool is found to be loose during use, it shall be tightened in time.
6、搬運工具時不可提拉電纜線，并注意輕拿輕放，防止震動和摔碰。不用時應放在通風干燥處。如發現受潮應及時進行干燥處理。不可與酸、堿等有害物質氣體接觸或存放在一起。
6. Do not lift the cable when handling tools, and pay attention to handle it gently to prevent vibration and collision. When not in use, it should be placed in a ventilated and dry place. If moisture is found, it shall be dried in time. Do not contact or store with acid, alkali and other harmful substances and gases.
