I have had a TS75 EQ and love it. However, the riving knife is no longer aligned with the blade. When I cut it holds back and then springs into the gap. Not good. I can't find anywhere to adjust it. I have taken the knife completely out, cleaned it, adjusted it closer to the blade per the 2-4 mm spec but it still wiggles left and right. I don't think it should do that. Any thoughts?
