I manage to remove a crank dampner bolt that was supposed to be torqued to 350 foot pounds with it. When I tried to use the air impact the whole Crankshaft wanted to turn I believe due to the fact that it creats a lot of torque. I tried the electric impact and it took a lot of rapping but the bolt came loose.
It is like any tool it has it limitations and advantages.
Where I worked the had an electic impact AC current that plugged into a wall socket. I did not like that one at all.
