The Unisaw's rolling base is activated by a foot lever that raises the base's feet off the floor so it can roll on the two wheels at the other end of the base plus the third wheel under the foot lever. The lever has two downward-facing curved edges that act as cams on a steel plate underneath.
I think my cams may be wearing out, or eroding enough that they don't hold the saw up off the floor for long when the foot pedal is lowered. When I step down on the lever to start rolling the saw, it can roll a few inches along the floor, but then pops back down, slipping back off the cams and popping the foot lever up again –– and stopping the saw's rolling where it lies.
Can these be adjusted? Or can one buy a replacement lever/cam assembly for this base? The base part number, I think, is 50-289 –– the one for the 3 HP saw with 52" Biesmeyer fence.
