It's a Belsaw. Good score.
I can't remember exactly, but the roller tension and vertical
position adjustment is rather crude. It sounds like the roller
may be a little low and/or under a bit too much tension. If
it doesn't put a divot in the work, I wouldn't fuss with it. If
it is marking the work, you may find that sticking a washer
under the spring on each side changes the tension/height
relationship favorably.
The height adjustment screws are rather well-done on the
Belsaw, though they can wear and get sloppy there's not
much backlash. Leave the handle on and you'll be able
to see the table position creeping by the location of the
handle, if it's creeping at all. With some head scratching
you should be able to mount a $30 6" DRO on the machine.
You can spend more but they all are pretty much the
same I'll wager. Check ebay for 6" dro.
