Hi - I bought this band saw almost 4 years ago and have enjoyed it. Lately it's started tripping the breaker (it's the only thing on the circuit and that has never been a problem before.) Today I put a new blade on thinking that a dull blade might be contributing to the problem. No change. Breaker is tripped after only a few seconds and there's a hot smell. The bottom of the motor is hot to the touch but not alarmingly so. The motor does not appear to have sawdust in it but I've not taken it apart yet. The belt tension seem fine. A slipping belt might contribute to the smell but shouldn't cause the breaker to trip (would it?) Before I shell out $200 for a new motor does anyone have a similar experience or a better idea? Thanks.
