How much use/how many starts until RO 150 FEQ won't turn on (assuming it's an overheat problem)?

[Festdewalkita]

RO-150 FEQ connected to CT Mini I. Fall day here in the home shop, it was 81F (27C) on the thermometer stuck to my duct. Giant fan was on, so I didn't think it was too hot.

I had 8 pieces of 4" wide ply to sand (both sides); 4 pieces that were 24", 2 that were 18", 2 that were 6". I would sand, then turn off, flip, and clamp...rinse, repeat.

I didn't finish. With maybe two or three to go, I swapped out the sandpaper and went to turn it on...nothing. I had noticed that one time about three or four pieces prior (but after a couple minutes break, it started up again).

I came back about 10-15 minutes later and finished, no problem (as a matter of fact, I sanded all the pieces over...I noticed almost all were shiny when sanding with P120, so I apparently should have changed the sandpaper a awhile ago).

I know it's a big sander that pro'ly has a big startup amperage draw, so I'm guessing it has a lot of Reactance (Impedence?)...my 240VAC Dust Collection system has a max 6 starts per hour limitation. Is there something similar for the RO 150? If so...what is it?

Or...

...is this not normal and it's time to send in for service? It's still under warranty.

There is a temperature sensor probe in the motor, so perhaps it had just over heated.

I don't know how often you check the cord connection to the tool, but make sure that is tight. Also take that loose and look at the end of the cord for any discoloration as well as the tool pins for discoloration. Perhaps an intermittent connection there?

I did not notice anything unusual, but appreciate the prompt. What I didn't say is that I am going back and forth between the RO 150 and my ETS 125 with the 205316 Poistioning Aid, so every time I unplug and replug I'm looking at the Plug It-Power Cord...I just went and doublechecked, and sure enough, it's pristine.

My assumption wasn't whether my use case is triggering the thermal cutout, it was whether the tool's thermal cutout is working within its desgin specs...as evidenced by other FOG members' experience.

I'm trying to gauge whether the cutout is tripping too early...or...if other people thought their similar problem was due to a thermal cutout but came to find out it was really a bad on/off switch...or...et cetera.
