noise and smell

i have a craftsman 10 inch direct drive table saw, Model #137248880. ive had it for around 6 years, of which it has seen around one year of use. it has worked fine, up until yesterday. as i turned it on, i heard a rather ugly grinding type noise coming from the motor. there was also a burning type of smell, but no smoke or flames. i cut a piece of 1/2 inch stock, and it cut it as usual, but i am concerned about the noise. i checked the arbor and there is no play. should i try and replace the motor or bearings or armature? buying a newer, contractor table saw is not in my immediate plans, but i dont want to burn the motor up or risk injury. any ideas? i checked online and couldnt find any other answers other than perhaps the bearings may be bad.

thanks in advance.

not likely

A saw with little use will not have a bearing issue...as a rule.
If you can blow out all the dust from the cooling vents on the saw with the motor running and no blade on the saw. Use a air hose and a small nozzle end and blow into every hole you can find several times. It may have just been a dust issue and you will be fine.
Other than that it could be that the brushes are worn, but that too is unlikely with limited use. Just use it normally, keep the dust out and see what happens. It could have been the motor needed a smoke break and now it's fine...... bill

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

could be this ....

a sliver of cut off got hung up between the blade and the arbor and got ground up when it first came on. I don't like to hear the words Grinding Sound when referring to a machine with bearings however.
Rotate the blade by hand and listen real close for a "tick" as the blade goes around full circle. .... if you get one that's not good.
Of course unplug the saw first. bill
A loose screw or nail rolled into the blade opening? Do you own a cat? Check to see if he's still around....
