1. 在定扭矩電動扳手接通電源前，檢查電源電壓是否與本產品銘牌一致，是否有接地裝置。當電源電壓超過+10%時，應采取穩(wěn)壓措施，否則會影響控制精度。接地不良容易引起事故。
1. Before the fixed-torque electric wrench is connected to the power supply, check whether the voltage of the power supply is consistent with the nameplate of the product and whether there is a grounding device. When the power supply voltage exceeds + 10%, voltage stabilization measures should be taken, otherwise the control accuracy will be affected. Poor grounding can easily cause accidents.
2. 恒扭矩電動扳手的環(huán)境溫度為-10℃-40℃，過高或過低都會影響控制精度。
2. The ambient temperature of constant-torque electric wrench is - 10-40 C, too high or too low will affect the control accuracy.
3.螺紋螺栓的初始扭矩不得大于工具額定扭矩的70%。螺栓達到額定扭矩后，不得復扭。
3. The initial torque of threaded bolts shall not exceed 70% of the rated tool torque. When the bolt reaches the rated torque, it shall not be twisted again.
4. 當工具用于拆卸螺栓時，其扭矩不得大于額定扭矩值。正常情況下，扳手未擰緊或螺栓銹蝕嚴重，不宜用扳手拆卸，以免對工具造成損壞。
4. When the tool is used to disassemble the bolt, its torque shall not be greater than the rated value. Normally, the wrench is not tightened or the bolt is seriously rusted. It is not suitable to use the wrench to disassemble, in order to avoid damage to the tool.
5. 當改變旋轉方向時，必須等到電機停止轉動。
5. When changing the direction of rotation, the motor must wait until it stops turning.

6. 當扳手自動停止時，松開開關(如果開關一直開著，扳手將在5秒后自動啟動)，等待4-5秒再啟動扳手，否則扳手無法啟動。
6. When the wrench stops automatically, release the switch (if the switch keeps on, the wrench will start automatically in 5 seconds). Wait 4-5 seconds to start the wrench again, otherwise the wrench will not start.
7. 螺栓直徑的大小對控制精度有一定的影響。在施工中，采用同類型螺栓連接對扭矩值進行校核。
7. The diameter of bolt has a certain influence on the control accuracy. In construction, the same type of bolt connection is used to check the torque value.
8. 機器應在工作前空轉3-5分鐘。運行中發(fā)現(xiàn)電機火花大、聲音異常、扭矩不穩(wěn)定時，應立即停機檢查。不要與疾病打交道。
8. The machine should be idle for 3-5 minutes before working. When the generator is found to have large spark, abnormal sound and unstable torque during operation, it should be stopped immediately for inspection. Don't deal with illness.
9、定期清洗和更換潤滑脂，一般在工作5000次后，應進行清洗和加油，以延長使用壽命。
9. Clean and change grease regularly. After 5000 times of work, it should be cleaned and oiled to prolong service life.

10. 主機控制儀表上的電源開關、碳刷、保險絲等都是易發(fā)生故障的易損件，應經(jīng)常檢查，及時更換。
10. Power switches, carbon brushes and fuses on the host control instruments are all vulnerable parts which are prone to failure. They should be checked regularly and replaced in time.
11. 使用過程中工具螺絲松動，應及時擰緊。
11. Tool screw should be tightened in time.
12. 搬運工具時，請勿拉動電纜，輕拿輕放，以免振動和掉落。不使用時，應放在干燥通風處。如發(fā)現(xiàn)潮濕應及時干燥處理。請勿與酸、堿等有害物質接觸或貯存。
12. When handling tools, do not pull the cable, take it lightly to avoid vibration and falling. When not in use, it should be placed in a dry and ventilated place. If dampness is found, it should be dried in time. Do not contact or store with harmful substances such as acid or alkali.
