Should be able to adjust the lock lever down tighter, sounds like its slipping on the belt. Had that happen on my 652 before. Don't remember the procedure as I haven't run Foley in a while, but it was pretty simple. Should be able to look at the lock system and see how it goes, otherwise manual or look on line. Sorry I can't be of more help but I think your in the right area from the sounds of it.
