  Intelligent electric torque wrenches have been used in all walks of life, and many people are familiar with them. However, some details are still very important. In the process of operation, we have more precautions.

  Precautions for operation of intelligent electric torque wrench

  1. The diameter of the bolt has a certain influence on the control accuracy. The same type of bolt connection should be used to calibrate the torque value during construction, and it should be checked and calibrated after a period of use.

  2. The intelligent electric torque wrench should be turned on for 3-5 minutes before working. If it is found that the motor has large sparks, abnormal sound and unstable torque during operation, it should be stopped immediately for inspection, and do not work with illness.

  3. The intelligent electric torque wrench should be cleaned and replaced regularly. Generally, after 5000 times of work, it should be cleaned and refueled once to prolong the service life. 4. The power switch on the main unit, the carbon brush, and the fuse on the controller are all vulnerable parts, which are easy to cause failure, and should be checked frequently and replaced in time.

  5. If the screw on the tool is found to be loose during the use of the intelligent electric torque wrench, it should be tightened in time.

  6. When carrying the tool, do not lift the cable, and pay attention to handle it with care to prevent vibration and falling. It should be placed in a ventilated and dry place when not in use. If it is found to be damp, it should be dried in time. It should not be in contact with or stored together with harmful substances such as acid and alkali.
