1、接通电源前应先查看电源电压是否与本产品铭牌相符,是否有接地装置。当电源电压超出+10%时应采取稳压措施,否则会影响控制精度。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、工具使用的环境温度为-10℃-40℃,过高过低都会影响控制精度。
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. 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、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 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、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, 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.
定扭矩电动扳手操作注意事项
Precautions for operation of constant torque electric wrench
1、螺栓直径的大小对控制精度有一定的影响,施工中应用相同型号的螺栓连接付来标定扭矩值,而且使用一段时间后还应进行检验校定。
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、工作前应开机空转3-5分钟。操作中如发现电机火花大,声音异常,扭矩不稳定时,应立即停机检查,切勿带病工作。
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、定期清洗和更换油脂,一般在工作5000次后,应进行***清洗加油,以延长使用寿命。
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、主机上的电源开关,碳刷,控制仪上的保险丝等均属易损件,容易引起故障,应经常检查,及时更换。
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、使用中如发现工具上的螺钉松动,应及时紧固。
5. If the screw on the tool is found to be loose during use, it shall be tightened in time.
6、搬运工具时不可提拉电缆线,并注意轻拿轻放,防止震动和摔碰。不用时应放在通风干燥处。如发现受潮应及时进行干燥处理。不可与酸、碱等有害物质气体接触或存放在一起。
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.
