A month ago my brake activated when the blade touched my intra miter gauge. My fingers were never in jeopardy, just a dumb move on my part for not paying attention. So the system worked as you'd expect it to -- blade stopped and retracted in a millisecond, leaving 2 tiny nicks barely 1/64" deep in the aluminum.
But 5 new brake cartridges later (1 from Amazon and 4 from SawStop), my contractors table saw is still sitting in the garage lonelier than the MayTag repair man. That's right, none of the cartridges worked. Funny because my dado cartridge mounts perfectly and purrs like a kitten when I turn on the saw.
Three of the 5 bad cartridges are Rev 2s, which won't lock down, and the other 2 are Rev 3s (apparently that's how you distinguish the 2 generations), which lock down okay, but when you turn on the machine, the motor shuts down in about a second.
Finally Friday, SawStop, after weeks of having me do everything under the sun trouble-shooting the problem, apologized, saying it's not my table saw, that the company has received similar complaints and that SawStop's engineers have concluded there's a problem with both generations of cartridges, or at least from the batches mine came from. I was told by one of the trouble-shooter techs that's all they know to pass along at this time, and SawStop is working toward a fix and would let me know as soon as they resolve the problem.
Curious if anyone else has run into this issue.
