I'm new to this form. So if this is the wrong place to post the question let me know. The truck is a 1992 Pierce Arrow 100 ft Aerial. We have only a short time and we are still figuring thing out. We have a problem with the platform not leveling. It worked when we got the truck home from Indy. There is a switch in the cab to level it when you need. The switch lights up but the platform doesn't level.
