Haven't posted before but I'm looking for advice. I'm setting up a brand new Unisaw. The blade stops need to be adjusted. I'm not getting a 90 reading on a Wixey; very close but I want it set up the right way. I unlocked the stop on the front of the saw and the manual says to use a 6mm hex to adjust the stop. I cannot get the wrench to fit in the socket. It is so deep that I can't see what I'm up against. Thanks for any help.
