I know it's an older post but....
Hello Matt, cruise to Hobart's website (I used Hobart Food Service) and follow the links to equipment manuals where you can download any of the spec sheets, parts manuals or operators manuals. they used to require a login ID but don't anymore.
I suspect that you've already figured this out but sometimes the bowls need a pretty good snap of the wrists to get loose. Just be sure the blade assembly is off the machine before you loosen the bowl as it will likely stike the blades otherwise. FWIW, most used bowl cutters have improperly adjusted blades. They want to sweep withing 1/32" of the bowl. I have three bowl cutters, all bought at auction and all had very poorly adjusted blades (dull too...)
Are you in Upstate NY? If so I may be close by (I'm in the Auburn/Skaneateles area).
