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.
