We purchased this unit used. It worked before we took it out of the home. Rode it up and down. The mistake we made was that we did not remove the seat. It was at the bottom when we took the rails apart and loaded it into the truck in
2 pieces. All I have read says that you remove the chair at the top of the rail. We did not receive a hand crank. We have now hooked the power back up. The chair and rail have power sitting on the floor upright on the brackets. The chair of course is sitting at an angle because the rail isn't going up the stairs. We cannot get the chair to move on the track...not sure why but it won't move. The other question we have is can the seat be reversed to operate on the other side of the stairs. It will work on the left side, but would be best on the right side. Any HELP appreciated!
