How do I adjust Z-Axis angle?

[Acmeaviator]

I have a BT-48 and I need to adjust the angle of the Z-Axs - I'm not sure what the proper sequence is to do so. The "silver" colored tracks that the router mount slides in are not perpendicular to the table. I know this is not support but I'm sure one of you have come across this and know how to correct for it:D

Does your outside guide rail wheels have excentrics on one set each side..?
