I picked up an RO 90 last week and set about sanding. Maybe 10 hours of use in it started to make an odd noise that I don't think it made before. I first started hearing it when I was starting and stopping it. I also found a few speeds where it does it all the time.
Here's what it sounds like:
Normal or not? Call up Festool? Since it's so new, should it be a swap for a new one?
Any ideas?
