I have a Ryobi RTS20 table saw and it recently started to make an odd noise when running. It makes a sort of squeaking/chirping noise like something is slipping and I can hear the pitch of the blade fluctuate when in the past it had an even hum/whine to the blade when it was running. I checked my manual and nothing in there mentions this and it even says that nothing on the motor/drive assembly should need lubricating for the life of the saw. I think the blade may be slipping but the washer and nut are firmly pressed against the blade so not sure how it could be slipping. I tried several different blades and all make that noise. It seems to cut fine but I am very nervous about using it since it just doesn’t sound safe.
Has anyone else had a similar problem, not necessarily with a Ryobi, but with any table saw where it suddenly starts to make this noise. I have already sent an email to Ryobi about it but honestly not sure if they will be of any use. And yes, I know Ryobi is a rather cheap table saw but it is what i could afford on my budget at the time and I really don’t have $200-$300 cash to even buy a decent used table saw at this time.

Have you checked the brushes? (part #24 in the diagram)

Scott may be right about the brushes. If they have worn so much that the mounts are making noise it may be too late (they will have damaged the armature; number 11 in Scott’s diagram picture), but maybe not. Hard to say.

In any case, call Ryobi parts to order brushes (the number should be in your owner’s manual) and do not use the saw again until you install them. They are easy to install, by the way, and as best I can tell the Ryobi miter saws, Ridgid universal motor table saws (the jobsite versions), and the Ridgid miter saws all use the same brushes. I have ordered a number for those various tools to keep on hand as spares and they look the same.

A brush replacement for Ryobi and Ridgid saw motors (and many other brands, too) is about the easiest thing you can do as part of maintenance. Heck, they are easier to replace than replacing blades.

Thankfully, brushes are cheap to buy.

sorry about being a bit late on replying – yes, the brushes were just a pitiful site. I guess i just figured that the brushes would last alot longer then they did since i don’t think i used the table saw that much. But i guess the speed the motor runs at and the load gets to them. I have some on order and hoping that is all i need. Thanks.

well, finally got my brushes in and changed them but the table saw is still not working right. The pitch of the motor/blade seems to skip and not hold a consistant speed even with nothing being cut. I can’t find anything obviously wrong just doing a visual inspection and it isn’t the saw blade itself cause i tried 3. It is like the washer pieces that hold the blade are not pressing down tight enough and that the blade is slipping, but I can’t get it any tighter without having to use a hammer or a very long handled wrench, and that seems like it would be too tight.
