I have a six year old Jet 14CS Bandsaw that is giving me some maintenance/mechanical problems. Recently i started to notice that it was bogging down in fairly easy cuts- pine, ash, etc. This occurred to the point of the GFI breaker on the outlet popping and shutting me down. I hadnt changed the blade in a while, so i put on a new blade, adjusted the tensions appropriately and started up again. I thought it was better, but within less than 15 minutes of work, the same thing started happening. The belt tension and appearance seems fine. But the motor gets very hot when this happens. I dont know if i have a motor problem, or what. I do think that the belt looks ok and seems about right with tension. Mechanics is not my forte, so—–
Any ideas or suggestions will be much appreciated. Thanks. Marc

A few questions to answer first. Are you running it off of an extension cord ? At the 6 year age I'am not sure if it's an open or enclosed fan cooled motor. which ? Are you getting full voltage at the Bandsaw ? How freely will the motor spin by hand ?

Thanks for the questions/interest Bruce. I have not had any problems with the electrical previously. Worked on Hickory without an issue in past, with same hook up. So i think this is intrinsic to the bandsaw. I am not using an extension cord.
To be honest, dont know if it is an open fan or enclosed, but if the fact that i dont see a fan helps, i dont??!!
It seems to move pretty freely, no binding or rubbing noises.

Look at the pully end of your motor, If it looks like a solid cast with no ventilation holes and the other end has a sheet metal bell ( fan is under there) Its an enclosed motor. If it's an open motor, My concern was bearing lubrication and dirty windings. If thats the case blow it out and relube the bearings. I would still check all the wiring,the plug and outlet and even the breaker. Loose connections, weak breaker, starter switch and corroded terminals/contacts can cause excessive amp draw and cause fires. Exhaust all possibilities first. Then call a buddy that has an amprobe and find out what the motor is drawing amp wise. If it exceeds the name plate data with no load you have a problem. Remove motor and have it checked out by a local motor repair facility.

Thanks Bruce, will check it out. marc
Start looking for a new motor. That's exactly the symtoms mine had. The smell of burnt windings lingered for a couple of days. This was a jobsite saw so I replaced the motor with an older Unisaw RI motor untill I found a 1hp Dayton on eBAY for $40.

Follow Bruce...."Are you getting full voltage at the Bandsaw ?" Before you go off trying to find a place to spend $300 (new motor), check everything between the saw and the electrical panel. There are numerous places the voltage can drop off.

Have you tried turning the wheels by hand when this happens? It's possible that something is binding the band or one of the wheels.
