It can be done I had to do it to get JunkYard out of a guys basement with that same turn. Youll want 3-4 guys to keep the machine from bumping walls. lift and carry it with the translit down and strapped to the body of course with the legs off.Make sure the back box or translit is going up the stairs first. when you get to the turn lay the machine down with the back on the ground and the coin door in the air. rotate it and lift and carry so the coin door side is the first to make it up stairs.
