What should be paid attention to when using intelligent electric torque wrenches on construction sites?

The use of intelligent electric torque wrenches on construction sites is a tool for comparing mechanical production, installation, or disassembly. For construction site workers, it is not unfamiliar, but what aspects should be paid attention to when using intelligent electric torque wrenches on construction sites to ensure that the electric wrench has a good lifespan?

Precautions for using intelligent electric torque wrenches on construction sites:

1. The size of the bolt diameter of the intelligent electric torque wrench has a certain impact on the control accuracy. During construction, the same type of bolt connection should be used to calibrate the torque value, and it should also be checked and calibrated after a period of use.

2. The intelligent electric torque wrench should be turned on and idle for 3-5 minutes before operation. If there is a large spark, abnormal sound, or unstable torque in the motor during operation, the machine should be stopped immediately for inspection. Do not work with a problem.

3. Regularly clean and replace the grease of the intelligent electric torque wrench. Generally, after 5000 operations, it should be cleaned and refilled once to extend its service life.

4. The power switch, carbon brush, and fuse on the controller of the intelligent electric torque wrench are all vulnerable parts that can easily cause malfunctions. They should be checked regularly and replaced in a timely manner.

5. If the screws on the tool are found to be loose when using the intelligent electric torque wrench, they should be tightened in a timely manner.

6. When transporting tools, do not lift the cables and handle them gently to prevent vibration and impact. When not in use, it should be placed in a ventilated and dry place. If the intelligent electric torque wrench is found to be damp, it should be dried in a timely manner. Do not come into contact with or store together with harmful substances such as acids, alkalis, etc.
