Folks -
I'm running into 2 problems with my 10-20 sander, and was looking for any advice on fixes:
First, the circuit breaker which protects the sander (main) motor seems to be flipping off without much reason, and doesn't reset well. The motor isn't hot to touch when it flips. The breaker reset switch, when pressed, will make the drum start to turn, then it stops. After maybe 5 minutes, the drum will start properly and run. I could see this happening if the motor had been under heavy usage, but that's not the case. Does this mean a bad circuit breaker? Or a motor going bad? How would I check the breaker itself?
Second, when I was looking into the breaker problem, I noticed that there was oil under the machine, which seems to be coming from the conveyor belt motor (which is not protected by that circuit breaker. The conveyor belt keeps right on running when the breaker flips). It appears to be leaking around where the electrical cord enters the motor case (it enters at the bottom). The motor runs, it makes noise when it runs but nothing that sounds particularly wrong, or squealing. This is something I've never heard of or read about. Would such a thing possibly be repairable by me? A new motor is available from Jet, but it'd be $200, over 25% of the cost of a new machine.
Thoughts, advice, ideas? Many thanks -
