Generally, 32mm and 33mm sockets are used for semi-trailer tires. If the pressure and displacement of the air compressor can meet the requirements, it is recommended to choose a pneumatic wrench with 100mm blades. Of course, a pneumatic wrench with 106mm blades is also available, but the price will be higher. We recommend using the MELEVEY M-866 model.

1. To protect the lifespan of the pneumatic wrench, we recommend installing an oil-water separator and an oil injector in the air compressor pipeline;
2. Please ensure daily drainage of the air compressor and air filter;
3. Check and maintain the pneumatic wrench daily, add oil to the inlet before use, and prohibit adding oil with too much viscosity, otherwise it will reduce the power of the air compressor motor;
4. Before use every week, the front shell needs to be removed and a small amount of high-temperature lubricating grease should be injected into the striking area to provide lubrication and wear resistance;
5. Pneumatic wrenches are suitable for air pressures of 6-8kg/c ㎡. Excessive or insufficient pressure can damage the performance and lifespan of pneumatic wrenches;

1. Before use, please read the accompanying manual carefully
2. During the use of tools, please wear impact resistant goggles, face shields, and earmuffs
3. When linking the air compressor, please ensure that the tool is in the closed state
4. When changing tools, whether before or after use, please remove the air compression tube first
5. When using tools, do not wear jewelry, wear loose hair, and do not wear loose clothing.
