re: Table saw question

When I bought the saw and brought it home, the first thing I did was start at the beginning of the manual and go through every step in setting it up. I will happily post scans of the manual, page for page. Nowhere does it mention checking the 45° to slot alignment, nor any backlash adjustments. I did completely clean the saw and lube with spray graphite. I also clean the saw regularly and re-lube it. I’m not OCD, but I take good care of my tools. My manual (nor the online manual) also does not show any way to lock the handwheels, nor does a visual inspection reveal any way to do so. Is there some trick to this?

I did get the 45° to <.001 this morning. I made a couple of shims out of some sheet metal I had and wet sanded them to .027 (the actual difference). I may be making a mountain out of a mole hill, but it’s my mole hill to do with as I choose.
