Strange sounds on my DeWalt sliding compound miter saw

The saw starts slow and when I turn it off there is a strange almost grinding sound. I have stopped using it until I find out what s going on. Any suggestions? Thanks

I think it's sawed it's better days.
Slow start could be a problem with the starter switch, cap, or winding, and the grinding sound would suggest either starter switch or the obvious bad bearings or gears.
Do you think it is fixable?
Could it be the break?
Thanks for responding
Basically, you have to diagnose it first, then decide if it's worth fixing. But of course the first question is whether it's worth diagnosing.
How are you with mechanical things?
Needs new drive gear
I had a DeWalt slider that had the same issue. The drive belt from the motor is connected to a small splined pulley that engages with a gear that drives the arbor. Take the drive belt cover off and then the drive mechanism. Once you start taking things apart it will be obvious where to go next. The damaged/worn part will be very obvious. Look it up on the DeWalt part diagram and order a new one.
Alternatively you can take it to a repair guy who will charge more than the saw is worth. The part cost me probably $20 and I got to curse the saw for good reason that day. I finally sold it but it ran fine when I did. At least the drive mechanism ran fine. There was something about that saw that didn't let me ever warm up to it.
The saw is probably really worth fixing and its an easy task.

Procrastinate and your gonna pay.
It's not the belt but rather the belt pully and other stuff that the belt drives. If you don't fix it now I believe the worn part will soon impact the next mating one and so on down the line. But it's your choice.
thanks for the heads up..I'll open it up again and give it a look see..
