If you're ripping longer wood, you need either a helper or an outfeed table that supports the wood. The weight of the outfeed will affect what you're attempting at the table, and is indeed dangerous. When i set a width of cut, am not using a steel square and a table slot. Only a tape rule with finer measurements with end butted up against bottom of fence and inside measurement graduations against edge of chisel tooth (front and back of blade). This checks what actually matters most.
If you can't get the fence aligned doing this, there is likely underside adjustments to square up the table top. Don't presume anything, and if you don't have one that model's owner's manual is likely available on the net.
I'll recheck the other side of the blade/table/fence and the teeth but I don't think I could get it any more square. I was a mechanical designer in the old days, so I'm pretty good at making measurements. Maybe I'll get my calipers on it.

I did find the manual and read it before I messed with the saw, but I wasn't sure what was causing the binding problem.
