Hobart A200 mixer

Hi all!

I'm new to the forum and need help with an A200 I just acquired. It is old! I'm not sure of year.

Current issue is the bowl lift lever. It won't raise or lower more than 1 inch. It sounds like it is hitting something inside the neck. My question is do I take the head off to get to it?? The only literature I can find is a parts breakdown that doesn't show much. Any help is appreciated!
