There's a lot of subtleties to the proper function of a PW press. More than we can go over here. If you think it's seen a lot of use, you may want to consider having them rebuild it. I have 2 PW presses and had problems with one I chased for over a yr. It was a press a group of us bought 20 yrs ago. It had been used by a friend who was heavyhanded and some things in the indexing system needed changing. Also, get a few of the plastic wad guide fingers to keep around and change it now. This little plastic part can look o.k. but give you headaches. Personally, I'd pull the top off the press and take the indexing plate off and clean it, and the gears, lube and reassemble.
