Purchased the delta 34-670 table saw on Sunday. Seller told me that the on board fuse would kick off with a second of turning the motor on. Took a $25.00 gamble on it being a fuse/ motor brush problem.
Got it home, removed the motor, took the motor apart and cleaned out the saw dust and visually inspected it. Brushes look great, lots of material left on them. The rest of the motor looked to be in good shape, no melted plastic or metal. Everything spins nicely. Reassembled the motor and checked the motor with the belt on(no load on the motor). This time it dosen’t pop the on board fuse, it runs until the 120 20amp breaker in my box pops.
Did a little reading research I find my amperage may be to low at the breaker box to kickthe motor on. So switch out the 120 20amp breaker to a 120 30amp breaker. When I turn it on, the motor runs for about 40 seconds, some arcing and flashing near the internal wires of the motor, some smoke, then it stops and kicks the GFCI outlet.
Did I buy a great paper weight? Why is the motor now running for 40 seconds and kicks off and smokes? Your input would be appreciated. John
