Topic tags/keywords: question tablesaw

Hi LJ’s. I could really use your help on this. I have a 12” Foremost TS that is having motor issues. I ripped a piece of wood and it worked great. I turned it off, got another piece to rip, turned it on, and it took about 3-5 seconds to get up to speed. Before, it only took a second at most. I tried to rip the wood, but there was very liitle power under load. Bad motor? Any help would be GREATLY appreciated. Thanks!

I’m not familiar with a Foremost table saw, but depending on what type of motor you have, it could be several things. If it is a capacitor-start motor (AC), the capacitor could be bad. In either case if it is a an AC or DC motor, it could be one or more the windings in the motor have shorted together. The motor will still run, but won’t have as strong of a magnetic field to turn the motor.

I had the same thought Sam did…bad capacitor. It’s gonna cost almost $7, and may take 5-6 minutes to fix it! ;-) Any motor shop or electronics surplus place should have a cap that’s close enough to work…the values only need to be close.

Yes, it does have a starting cap. I should have mentioned that originally. I really appreciate the help LJ’s! Thanks!!!!

I would check the pulley. I had this happen to me. The set screw that holds the pulley on the motor shaft loosened up and was spinning on the shaft. It took awhile to get up to speed and when I tried to feed a board it just bogged down.

Yeah my first thought was belt/pulley/linkage between the motor and blade. I’d check that before tearing the motor apart :)

Tony and Jimi, you guys nailed it. The pulley was loose and after a short easter egg hunt for the key, she’s running like a champ once again. Thanks, BIG TIME!!

Good to hear, hopefully they’re all that easy.
