The guide rollers are adjustable
I just happened to have a carriage head off the arm
to show you:
I don't know the recommended procedure for adjusting them, but I would guess...until the saw slides freely and has no lateral movement.....
BTW if the saw carriage does not slide parallel with the arm your kerf will be too wide. This could be a potentially difficult adjustment. The arm must be 90 degrees to the fence rail, but the fence is adjustable however, leave that for last. Make sure the arm seats in the 90 degree detent securely. Then make the adjustments to the carriage from that known setting. I would get the blade/carriage sliding parallel with the arm and worry about the fence being square last.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
