axam,

I looked at the manual and assume that you have located screws 60 and 61, and that you have discovered that by loosening these screws, the trunnion can be adjusted to bring the saw blade parallel to the mitre slot. Therefore, my guess is that as you tighten 60 and 61, the trunnion moves.

My only suggestion for this typical and frustrating problem (at least for me), is tighten the screws a little at a time. Paying attention to the order in which the screws are tightened may also help, tightening screws that are diagonal from one other.

For example loosen screws 60 and 61 just enough so that the trunnion can be moved. Then adjust the trunnion so that the saw blade is parallel to the mitre slot. Then tighten 60 just a hair. Then tighten 61 at the diagonally opposite corner just a hair, then tighten the second 60 screw and finally to the diagonally opposite 61, just a hair. Then check that the trunnion has not moved. Continue this process until 60 and 61 are snugged up all the way up. Then check that the blade remains parallel to the mitre slot.

The only other alternative I can think of is to set the trunnion so the saw blade is parallel to the mitre slot and then clamp the trunnion in place. After clamping, re-check blade alignment. Then tighten the screws, but following the diagonal tightening pattern is probably still a good thing to do. Of course the problem with this method is finding a place for the clamps.
