I'm retired and a total amateur/rookie woodworker. I bought a Bosch 4100 table saw about one year ago and I'm still learning how to use it.
For example, I was trying to make some accurate rips but wasn't getting the desired result. My 8 in long workpieces always measured about 0.020" wider at the far end. So I measured the fence/blade parallelism and found the fence too far from the blade at the far end (duh). Long ago I observed the fence moving a little when locking it but assumed that movement was squaring up the blade, not "unsquaring" it. Ha, ha, the joke's on me.
Before attempting to adjust the fence I measured the blade/miter slot parallelism. I measured about 0.008" error. I loosened the four bolts and, with some difficulty, moved the blade a tiny amount to about 0.002" error.
Then I went to the fence. The instructions are simple but very uninformative. It's just those two bolts. I don't get it. Anyway, I messed with it for a long time and finally got a good result.
I have not yet tested the accuracy of my 8 in cuts. Maybe tomorrow, busy today.
