Metabo PE 12-175 Thermal Shutdown

I

I'm having an intermittent problem with a 3 month old Metabo 12-175. At first, I thought it was running it on the same extension cord as the halogens.



In brief: The machine gets very hot, the thermal indicator light comes on the the rpm either decreases or stops completely.



I run the rotary 98% of the time at 2.5 to 3.0 speed setting.



Any Autopians experienced this with Metabo? I've sent an e-mail to Metabo US and will be calling them next week, but I thought I'd post this to check here first.



Thanks Everyone and have a SAFE Memorial Day Weekend!

Man, my metabo did something weird this weekend. I was using it at 3 to 3.5 for about an hour and when i was at the very last panel the pad would not move when I touched a surface but would move without touching it. It was very hot and I thought it was this thermal shutdown thing. I waiting a couple of hours and nothing... When I turn it on the light comes on for 0.5 second and goes off... I also feel a loss of power in that 0.5 second. The pad spins but stops as soon as I touch it on anything.
 
kapinnn: sounds like you had a similar experience. I took my Metabo to the warranty center here in Kansas City and they replaced a switch. That seemed to solve the problem. The unit still will get hot (not as much as before), but I can live with that.
 
When you have this problem, turn the Metabo on but do not polish, just keep it in your hands. This will decrease the hot.

Are you using pressure when you are polishing?

If you use polishes with low lubrication, the engine will be hotter in less time than if you use polishes with more lubrication.

But is an amazing machine ;)
 
Well the problem is that I can't even polish with it... =\



It turns on, it spins, but as soon as I touch it on a surface the pad stops. I took the head of the machine apart and everything is connected just fine. The light comes on as soon as I turn it on and goes off half a second after it. The machine also loses torque in that half second. I used this machine maybe 5 times so far... I hope its an issue covered by warranty.

You need to let the machine run at speed one until the light turns off if it goes into thermal shutdown. Happened to me many times.

ahhhhh, thank you my friend. I hope it works. I'll try it this afternoon.

I don't think that is your problem if it behaves like you described: "The light comes on as soon as I turn it on and goes off half a second after it. The machine also loses torque in that half second. I used this machine maybe 5 times so far... I hope its an issue covered by warranty."



The method of running it at speed 1 until the light goes off is to let it cool down from a thermal overload...... but yours hasn't had time to heat up yet. The good news is these guys have a 1 year warranty, 3 if you register it on the Metabo web-site.



So anyone with a Metabo make sure you hang onto your receipt and register it on-line to get the free XXL (3 year) Warranty. They say you need the XXL® warranty confirmation (sent via e-mail) and the original sales receipt for warranty service.

Well, thank you for the heads up. I'll check the manual when i get home and will register on their website. I hope it's not too hard to get it serviced...
 
One of the things I do now is run the Metabo on a dedicated heavy duty extension. Prior to that, I was using a multi-outlet cord with my halogens plugged in the same outlet. Those are 2,000 watts and the Metabo can draw 1,400 watts. I suspect I was overloading the outlet and drawing too much power for the rotary to function properly.,

The first thing I tried when my Metabo overheated was upgrading the extension cord to 12g. While it's a good idea to do that anyway, it didn't help. Changing my technique did.

Well, so I tried the running it at speed 1 and nothing. I guess I'm going to have to go to a service center or get this warranty thing going.



Thanks for the help!
 
I have a local friend who just got a metabo and his seems to be overheating somewhat as well. Mine has been rock solid since I bought it 10 weeks ago. Thanks for the reminder on the 3 yr warranty. I just printed that out, scanned it and the receipt and emailed it to myself. That way I will always have it.
 
gmblack, have you tried your friend's machine yourself? In my situation I attributed the overheating largely due to my technique. I'm just wondering if that's the difference between your's and your friend's.
 
No matter what I've done or what technique I've used with either my Hitachi or Black & Decker neither of them have shut down on me. I wonder if there is maybe a bad run of Metabo's?

I don't think it is bad run. IMHO it is because Metabos are smaller (so they can be lighter) so it is harder for them to dissipate that heat. Lightness comes at price.
