Help, I can't get off my creeper

The one I bought is a Worth,out of Fort worth Texas. I wanted a lift to handle a Dually Diesel truck.10,000 lbs.I bought it thru Justice Brothers as a man in our car club was a rep.Works for me,, about 12 years now. 3 of my friends that own businesses all have Rotary. 7 in total.Only one had a problem, shipped wrong order I guess. It didn't lift high enough,They sent out another and did the removal and reinstall.
