Festool ets 125 Req spins uncontrollably

[thebrazilianpainter]

Hello everyone.
Thanks so much for taking the time to help me solve this problem.

I have several sanders with the same problem.
I made a video so you can see how it spins uncontrollably.

Can anyone help me troubleshoot it and order the right part number?

Thanks in advance.

I'm not sure if I understand the issue. Does the pad not stop if you hold it?

It does not.. I will make a better video tomorrow to show how it works when I am sanding with it..

Thanks for your reply.

That issue is beyond my level of understanding on how to fix - other than sending it in to Festool. But I'm sure someone here will know what's up with that.

On the bright side, it looks like it's "gear driven" - so a cheaper way to have a Rotex.

Unfortunately this sander is not longer under warranty.

Thanks

I could be wrong but from the video it looks like it's not actually orbiting, just spinning?

I gave my ETS away so unfortunately can't look inside, but I know the basic design of most RO sanders have a weighted attachment that screws or clips onto the pad or shaft, which is what gives it the orbital motion.

First thing to do I reckon is take the pad off and have a look inside for any obvious things that need tightening or replacement due to damage.

I appreciate your message...
I will check on that tomorrow.

I'm pretty sure that there is a gasket/seal that makes contact with the top of the pad. This puts some load against the rotation, helping it stop. If I'm remembering right, it's somewhat of a wear item, not exactly a "consumable" but along the same lines.
