Ro 150e sanding mode knob is broken...
« on: April 02, 2018, 10:03 AM »
Hi Folks,
I'm very glad to have found this group - I've just joined in the hope that someone can assist me. About 20 years ago I bought a very expensive but very nice Festo Ro 150e rotary/random orbital sander. Since then it has had pretty heavy use - its had a new motor and I think at least 2 new rubber pads. Anyway I thought I'd lost it a few years ago until today when my brother returned it! It seems that I'd loaned it to him to build his kitchen (along with a number of other tools) and I'd forgotten to retrieve it (and he hadn't bothered to give it back!)
Anyway, I'm glad to have it back. It runs but I'm somewhat dismayed to find the rotary sanding-mode knob on the side of the metal housing has come adrift (or been removed) with the parts - such as they are - in a small bag. There's the green plastic swing-out knob, a small spring, a Philips head machine screw about 25mm long, a small keyed cap-like thing that seems to fit into the bottom of the green knob as well as some unidentifiable, vaguely copper-coloured curved bits of magnetic metal plate which look very broken!
I've had a tentative go at reassembling things but I can't see how it's supposed to work or how it goes together. In fact after checking the parts diagram at mmtoolparts.com it looks like there are also some parts missing. I'm thinking I should just buy a new switch kit (it's part # 487800 at the above web site). Cost posted to Australia will be about US$80!
My questions are:
- how can I find out how to carry out this repair? Is this a straightforward reassembly that would be obvious once I had a new kit of parts in hand?
- I don't yet understand how this mechanical switch works - anyone have any pointers?
- do people think it's worth it? It appears that the sander is 'stuck' in random-orbital mode (which is probably how I'd use it most of the time) but it would be nice to be able to switch it into rotary mode occasionally to make use of the brute power I know this thing is capable of.

Any help or insights would be much appreciated!
best wishes,
Sam.

I don't know if you have any local festool dealers, but if I order a festool part here, I don't have to pay shipping, so in your case that part would cost 57,70 AUD including VAT. (according to ekat on the festool.com.au site link to parts diagrams

Personally I would try to fix it myself, if you send it in for repair, you'd get a quote of how much it will cost to get it fixed, and if you find that too expensive there's a chance you get it back dissassembled to the last screw (and you might have to pay an examination-fee). You started with a functional tool and then you have a bunch of parts (happened to me with a shopvac I sent in to Makita repair)
