Product Usage Knowledge and Precautions

Pneumatic Impact Wrench Usage

When the input air pressure of the air impact wrench is 0.8MPa, the torque output is approximately 850N.M. When the input air pressure increases to 1.3MPa, the torque can reach 1200-2000N.M. Torque is directly proportional to air pump pressure. It is recommended to use an air hose with an inner diameter of 8mm or larger, shorter air hoses will deliver higher torque.

Pneumatic Tool Lubricator Usage

The lubricator features 1/4’’inch interfaces on both ends. During use, connect the head to the pneumatic tool’s air inlet and the tail to the quick connector. Unscrew the top screw to fill the lubricator with special pneumatic tool lubricating oil. Once installed, the lubricator will automatically and periodically lubricate the tool’s internal components, reducing manual oiling frequency and extending the tool’s service life.

Precautions

1.Install an oil-water separator at the air compressor outlet and drain it daily.

2.The air compressor requires a minimum storage capacity of 40 liters at 8 bar pressure and a power rating of 1.5 kW to start.

3.Regularly lubricate the pneumatic impact wrench’s air inlet—preferably daily with 2-3 drops of oil. After lubrication, run the tool idle for one minute.

4.Never use engine oil, only special pneumatic tool lubricating oil is permitted.

5.If use with 3/4’’inch air impact wrench, it is recommended to purchase a 10mm inner diameter and avoid spring-retractable bend hoses or coiled hoses.
