It sounds like there have been a lot of questions posted on the saw, but none of them completely answered my questions so here it goes.

New to wood working, fairly new to this saw. Purchased it used $100.00

I started my first serious cabinet carpentry project with this saw. Several cuts in and the on/off switch failed. Not a big deal, replaced it and it fired up right away. Two cuts later the motor would not start again. After much trouble shooting and reconnecting, I rapped on the motor and it fired up.

After closer inspection I see a lot of "spark" from inside of the motor. Now I periodically have to rap on it to get it going.

Do I have to replace the brushes.

I guess after posting this I realized that might be the best course of action. I looked locally for a Dewalt / Delta service center and found one. They have (4) brushes in stock for about $6.00.

I will pick them up today and see how it goes.

As long as I am in there, is there anything else that I need to replace? The belt looks great.

Thanks for the reply!

I will check tonight and report back. I just replaced the blade and did not feel any play in it, but I will confirm. I remember thinking that the arbor felt a little "tight", but it has felt that way since I have owned it.

What really got me was the light show when it is running. I think the motor casing is vented on the arbor side and you can see a lot of sparks in there when it is at full rpm.

If the brushes seem like they have a lot of life left the armature might be worn where the brushes rub against them, but you'd have to pull the motor apart to see. My assumption at that point is new armature or probably cheaper to buy a new motor. Hopefully a motor expert will chime in.
