Steve, make sure you pull the table all the way up until the locking mechanism clicks into place. It can seemed locked but I've had mine come down before. Also a nut inside the pedestal had come off so I replaced it with a nylock nut. Once you take the top off you will see it is a pretty simple set-up. I would be careful about fixing it in the up position. They are top heavy and come from the factory only screwed the floor. I have heard of a table pulling out of the floor while traveling with the table up. I ended up bolting mine down with 1/4" bolts and fender washers.
