Hello everyone,

I’ve got a Ridgid R4512 that I’ve been using for about the past year without any problems. Earlier today though, I was feeding some 3/4 plywood through it and it all of a sudden changed to a much deeper sound and much louder.

I turned the saw off, then back on again and the sound was gone…until I started making another cut. As far as I can tell, it’s not affecting the performance of the saw, but it makes me uneasy when it sounds different a year into it.

Any ideas as to what might be causing it? And how to fix it?

Thanks.

Get a look at the motor (look thru the vent slots) while it’s running.
I had a Delta contractor’s TS that made a deeper, louder sound that usual, and the brushes were sparking and there was a burning smell. 12min of operation or so later, it went belly-up.

I have the same saw. When I first got it, the belt was loose. I had to tighten. I would check it to make sure the motor hasn’t slid out of alignment. There are several post on LJ about how to tighten the belt if it is loose.

Thanks for the responses.

I should add, too…The sound doesn’t start until loaded, but it will continue after the cut is complete and there is no load. It only goes away if I turn the saw off, wait for it to stop, and then turn it back on.

Yea I check the belts first as address by DW833, with the saw off lift the motor up and then set it in the resting position check the belt tension with your finger. The belt shouldn’t give without firm pressure, then turn the belt by hand making sure no obstruction are hindering free movement. Take a close look with a flashlight to make sure the locking nut haven’t slip. I hope this is whats wrong easy fix if so just tighten up…best wishes BC

Well, I tightened up the belt and it seems to have helped. Only made one quick cut though.

I’ll put it through its paces tomorrow and see if it holds up.

A little update…I ordered a new belt over the weekend and I finally got it today. Holy smokes…cuts better than it did the day I bought it. I decided not to buy the Ridgid belt for $40 and instead found the exact same belt from an actual belt manufacturer for $2. That’s $38 left to spend on lumber.

Thanks for the followup. Since so many folks own that saw, it’d be useful to a lot of them if you’d post the details of the where you got the belt and the belt #....

Yeah, the belt # is 140J6 and it can be found from various suppliers on the web. It is a 14” 6-ribbed J-series Poly V-Belt.

The 135J6 would probably also work. It is the same thing, but 13.5” instead of 14”.

Have your say...
