It is a very good air wrench, you just have to work it at 8 bar so that it drops to 7 when you are at full to unscrew everything.
The tool is excellent.
But very, very heavy.
And it requires daily lubrication.
It also requires a high air flow, so get the largest hose your quick coupler can take

Relatively powerful, tested on wheels, it solves relatively comfortably on a 28 screw. Negatively, it is very heavy and the switches that adjust it are not of good quality.

Test on a rusty bolt, a 22mm screw, it unscrews relatively easily... (I didn't expect it) for the money it does its job and more for someone who wants it for normal use it is worth it and more.
