After spending about six hours of quality time with the ETS EC 125 this morning, the sander started shutting off on it's own. Turning it back on allowed about ninety seconds of sanding time, then another shutdown. I tested multiple outlets and plug-it cords, both through the CT it's hooked up to, and individually. Same results. I turned the dust collection sensor on and off; again, no difference.
I pulled out the manual to get the number for Festool service, and the only number supplied in the box is the German number. That seems like a big oversight on Festool's part. Now that I'm able to get online, I can get the number, so I'll call tomorrow.
The manual noted that the sander has overheating protection that will shut it down. I'm guessing that this is what's happening, but the body of the sander is not warm at all. Is anyone familiar with this problem/feature that could shed some light on how hot is hot enough to trip the protection?
I was sanding cedar panels that had been previously leveled out, so the sander was not under much load, final sanding at 120 grit. I absolutely love using this sander, but now I'm loving it a little less. My Pro5 is not here yet to use as a backup, so I'll be working on the remaining 140 sf of paneling with the Rotex if the ETS EC doesn't want to do the job.
