I dont know if its the blade or something, but in the directions it says the wheels aren't supposed to be rolling against the blade when the saw is on but not cutting. I changed out the the 1/4" blade to a half inch blade to cut a piece of mahogany that was maybe 2" thick. Anyways whenever I switched to the wider blade I noticed the top wheels on the left side wouldn't back away from the blade enough, so they kept spinning. I went ahead and cut with it anyways without any issues. Was showing him the difference between a jet and his little benchtop pos that wasn't cutting well. Anyways anyone have any solutions? It almost seems like the upper guide wheel assembly twisted a little bit.. These are ball bearing guide wheels, not the cheap sliding guides that other saws have.
