My first post here. Just bought saw two days ago and i alread f(#* up. OK, i went to adjust the riving knife cause it didn't look aligned to me; off to one side slightly. So i loosened the two bolts per the user manual (man were those suckers tight) but that didn't do it to my satisfaction. This is the part were i really screwed up; i also loosened the two set screws (now i know why they didn't supply an alen wrench that size). Well, i spent about 4 hours tightening/loosening but got nowhere. Anybody know the trick for this saw? I seems if i try to tighten the bolts to the same level i found them everthing goes out of whack; or i can't get the knife to ride the correct distance above the blade (and i'm just guessing on that distance). Is it time for a service visit? Would it be covered under warantee or the lifetime service agreement?
