I recently sent my Kapex saw in for a repair, under warranty, with great results. While in the shop, they also replaced the "warped fence", which I never noticed, (at no cost). My first cuts after getting the saw back showed that the fence was out of square to the blade. There are four screws to loosen or remove the fence, so I worked at several tries to get it perfect square and got it close enough for the job I was doing. Still, I figure there must be some easier way to square the fence to the blade, than my "trial & error" method. What do you do? How is the fence set at the factory?
