Table saw starts slow and the stops

Are you using a rip blade. Maybe slowing down the cut will help.

how thick are the boards you are putting through? maybe they are to thick
also have you oiled the blade ?


hope this helps

Hello vince....sorry to be the messenger but it sounds like your saw's motor is shot. You can purchase a rebuilt from dewalt. Joe

The problem you have is a faulty field coil, the Bosch saws unfortunatly have a bit of an issue with this. The coil can be replaced separatly so you won't have to replace the whole motor. Bosch has a 1 yr warranty on thier table saw so this is a warranty replacment provided the saw was purchased within the year. If not the coil replacment is still cheaper than buying a whole new saw, but should really be done by a service center because of the level of difficulty of the repair.

Two easy possibilities are that the blade is dull or that the wire is too small. The wire is likely to be a problem if you are using an extension cord. You could move the saw near to an outlet that you know to be wired with 12 gage wire (not 14). Or you could buy as short as possible 12 gage extension cord. If being underwired is the problem, you will notice that the motor comes up to speed much faster when wired adequately. You might also buy a cheap new blade to rule out the dull blade problem. If neither of these fixes the problem, then the motor has become "weak" because it has overheated just enough to cause some minor shorts between the windings. (If the shorts are major it won't turn at all and will trip a breaker.) In this case the motor can be rewound, but it will probably be cheaper and easier to just replace the motor.
Good luck, Al K

Sounds like it but does it have a capacitor (start/run)--what model/type motor is it? and go from there.

Sonmethings shorted out inside motor / strip and see if any debris is in there.

It has somehow repolarised from the negative side to pos side!!

Hello, the brushes are two gray sprung loaded electrical conductors. They are located on the inner main spindel of the motor (armature), when they start to wear out you will find that most electrical motors will slow down in revolutions. Experience has taught me that when an electrical motor emits smoke it has normally burnded out the armature. This in all honesty is not worth fixing as it is an expensive job, it is cheaper to buy a new saw. Sorry to convey bad news but I hope this clarifies thing for you.

Unless somewhat preformed, brushes have a tendency to arc like crazy and can produce heat and even smoke. I would remove the brushes and use a fine 'keyhole' type file to give them a little inside curve so they have better contact to start with.
