This listing has been updated! Apparently, another seller has used my pictures to create a fraudulent listing. I added a picture with the date to prove I have this impact wrench in-hand.
This portable gas powered 1" impact wrench runs great and is powered by a Stihl MS290 chainsaw. I believe it is used for a railroad application. Take a good look at the pics and see the new video. As you can see in the video it drives an 8" lag bolt into the 6x6 just fine.
Note: I buy equipment to re-sell. I try to test what I can, but I do not fully use everything I list. This item cranked up, idled, and responded to the throttle (see video). It has not been tested or used for an extended period of time. Buy with that in mind.
