The torsion shear electric wrench is composed of a host and a controller. The main machine of this torsion shear electric wrench adopts double insulation single-phase series excitation motor and deceleration mechanism, which has the advantages of novel structure, small volume, light weight and more reliability. Due to the static torsion structure, the operation is stable, no vibration, no impact, low noise, and the operator is not affected by the counter torque, so the labor intensity is low.

扭剪型电动扳手操作注意事项

Precautions for operation of torsion shear 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 the 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 work. 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，应进行一次清洗加油，以延长使用寿命。

3. Clean and replace the grease regularly. Generally, after 5000 times of operation, clean and refuel once 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 falling. 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.
