Compliance and Restrictions



Air impact wrench is fit for heavy vehicle tire changing, general mechanical works, and manufacturing equipment maintenance. It is easy to use, with an ergonomic handle that can adjust to multiple positions and an angled down exhaust that keeps the air away from you as you operate the wrench. Both the wrench and its applications are protected by the shock-absorbing rubber bumper.
