I found a picture of your model, and it is quite a bit different, although
probably with the same basic idea.

I think Doug's tip will do the trick for me. Thanks for the kind offer.

I've got a Model 315.175040 that sounds similar with the adjustment
rings. I can send you a copy of the pages in the manual that talks
about the adjustments if you want. I agree with Doug though, if you
want to make sure your bit is at the right height, use a gauge or test
piece!
