Alignment machine don't know how to use it. No time to mess with it. I am not sure if it has any issues, as I was never able to figure out how to use it.It's being offered in as is condition.No guarantees. I have had it for a long time, I think the last time I messed with it was about 10 years ago. As indicated by the date on the screen, it's just been sitting in my garage. I need the space more than the machine. Questions call 602-four0two-0one40
