New Holland 1034 stack wagon

Just a couple quick questions. Recently picked up a new toy, unfortunately I didn't get a manual. Everything seems to work as it should aside from a few sticky valves. Hopefully they will free up as I use the machine. First question is whether the slide on the bale table moves automatically as the second table pushes bales back or is the something I have to do. Second, what is the lever for under the bale table, it kinda ties in with the handle on the side that raises the bale catches up top.
