A few weeks ago I happen to set of the break by hitting my miter gauge. You have to really look for the the scatch on the metal bar. After I struggled to get the cartage & blade off at the same time I put a new cartage & blade back on. Now when I start the saw it makes a small squeal when starting. I checked the belt & it has the 1/4'' deflection it suppose to have. Also when I shut the saw off it makes a sound like the bearing is bad when it winds down...anyone else have this ?
