I have a Tradesman Variable Speed Scroll Saw. I only used it a few times and it quit working. It has a work light and it is still getting power to the light. The last time I ran it, which was a few weeks ago, it was for about 20 minutes. About 5 minutes later, I turned it back on and nothing. So I waited about 30 minutes and turned it on again, and i it was moving really choppy, not smooth at all. So I left it run for a few minutes without cutting anything and it seemed to work out the choppy problem and started running smooth again. I went to use it 2 days ago and it didn’t start up at all. Does anyone have any suggestions as to what the problem may be? Anything at all would be appreciated.

Thanks

Sounds like you might have a brush problem. See if you can remove the brushes and see if the contact point on the armature is clean, or maybe you have a broken wire on a brush.

Many motors have what looks like large screws on two sides of the motor if there removed you will be able to remove the brushis. Another cause could be a bad smitch or loose wire.

When you say remove the brushes, do I replace them, or clean them, or just remove them? What function do the brushes do for the motor? What could be wrong with the brushes that is keeping the saw from working? Thanks for the info guys.

Just buy new ones. Their not expensive you may have to grind them in to the shape of your armature or they might spark a bit not serious don’t worry get the supplier to explain it to you.Alistair
