It probably wouldn't apply to everyone, because you may not have it available, but this is a good reason to support your local dealer. If I had an issue with any of my Festool gear, it would go to them. This in the advantage of the big city though. My local dealer is a repair center too. Out of warranty is still going to cost you, but only for the repair itself, there is no shipping involved.
As ChuckS said, there comes a point where you have to question the viability of repair, mostly because of cost. The "disposable society" mentality has made it to where even getting parts to repair things is a challenge, nearly impossible with many of the box store brands. Then on the ones where you can get them, what is the cost? Either directly or in the case of time to ship/receive, plus indirectly, through your own time to diagnose, then repair. In a hobby shop, this is different, even part of the enjoyment, but in a commercial situation? Nope, you can't be without. Maybe the repair happens later, when you have the time or the parts do come in. At that point, you have a back-up another for a different space or you sell it? I can't see a business selling it, but the option is there.
