I've had this Hausfield compressor for quite a few years. Since I've been using the crap out of it with my nail guns here to get the house done it is showing it's years. Recently I've run into trouble getting it started. I will flip the switch and it will hum and through the breaker. If I give the belt wheel some turns it will usually finally get started. It may start again the next time or it may not.
I've looked on the motor to see if there are any brushes. Don't see anywhere there are any. It has two cannisters at the top which may hold a capacitor. Could the capacitor cause a problem like this? There is oil in the compressor motor. I'm going to try and change that to see if it does any good.
Do any of you mechanical giants have any idea what could be looked at that could be causing the problem?
