I have a Ryobi TSS102L miter saw, and when I try to get into the the bevel position, and it wont budge left or right. From what I gathered, I am supposed to put the saw upright, lock it in place, and then loosen the bevel knob in the back, and then position the level to the left for a bevel cut. What am I doing wrong ? Please advise! Thanks!
