Topic tags/keywords: question

I have a Dewalt Radial arm saw that is about 5 years old. Never had a problem and the saw is great for what i use it for. Cranked it up to today and noticed a weird noise so i unplugged. I checked the cover where the blade is and theirs no debris lodged in their. I turn the blade by hand and to me it feels like theirs a dead spot where it doesnt rotate smoothly. I removed the cover for the belt and it seems o.k. so i was thinking something is wrong deeper in the saw. Before i start randomly removing covers and screws ? Does any one have an idea what could be wrong. Is their a motor problem that could possibley be under warranty ?

Thanks for your input

Fred

Dewalt quit making the RAS somewhere back in the 80’s, so I’m guessing you have a sliding compound miter saw? You mention belt, try taking that off and then moving the blade to see if the problem might be in the arbor. While it’s off spin the motor (unplugged, by hand) to see if it makes any noise or feels rough. Then plug to back it and turn it on (belt still off) to see if notice anything. Giving us the model number would be useful, then those who own that exact saw might have an idea.

Could it be something stuck up inside it ?It surely sounds like that to me.Why not take it apart a bit more and see if there is any crud causing a binding of the blade.Alistair

I have the DW708, I removed the belt cover and was going to remove the belt for further inspection per your suggestion and my son and I noticed that there are two spots about 8 in apart from one another that are “bad spots” in the belt, they feel like the belt is cupped in those two ares and coincide with the above mentioned rough feeling. I guess the belt is worn out, will replace. In the mean time I wonder if I somehow caused this belt to wear funny. I might be doing something wrong when operating the saw. It seems to me that when i finish a cut i just let the trigger go and let the saw lift off the piece ? I wonder if i should let the saw stop spinning first then lift up ? Any thoughts ?

If it is five years old and get a lot of use it is probably just a worn belt. You said eight inches a part so it probably just hung up a bit and got worn by the gears. Just replace the belt and I wouldn’t worry about if the blade has stopped before letting it up, but don’t’ let it go freely ease it up.

Hope it works, if you still have the problem afterwards then you may have a belt wheel alignment issue, tension issue.
