4000 table saw motor

I really like the features of the saw. Motor is a different story. Right now I have replaced the brushes since the motor did not run correctly, this being only several hours aftergetting it repaired. What could cause this? Sounds like Bosch has major problems with motor units. Need some direction.
Thanks

Not knowing the problem you are having with your saw motor. We have noticed in the past, problems with the PC board failing. When this happens there are several things that could happen. For instance loss of power, motor not running at all, & motor running backwards. If your brushes are wearing out and you are seeing arcing from the motor you might also have a defective armature. I hope this helps.
