Is this normal?

So I fired up my new Flex 3401 DA last night to work on my glass top stove. It really seemed to get hot. Now mind you, I was applying some pressure to it, but not more than I would a rotary. My Dyna does not get hot like this. Is this normal?

richly I don't use a Flex but rather a Dewalt & PC. I've read extension. Ive read certain extension. Odds can make these tools run hot. Just wondering if you used an extension cord? If so was it different than your normal one?

Mine has the factory 30' cord.

The other thing is that I had removed the handle so I was holding the housing. I will try it with the handle back on to see if that makes a difference. My bad above: 25' cord, not 30'.

Do you mean the cord or the machine? Mine gets hot and if I use it for a long period of time it gets really hot. the cord never really feels warm.

All tools get hot after hard use over time but I've never experienced anything like what you're saying...

In fact, if you are holding the forward bale handle and the rear body handle you shouldn't feel much heat at all.

The head and body will get hot from the motor and gear drives but not enough to affect the handles where you hold the tool and this is normal.

I tried that too as I don't normally like handles and I ended up putting the handle back on.

I also tried a stick handle and come to the conclusion that the German engineers actually do know what they are doing...

Richy, I know what you mean, mine gets hot as well. Especially the metal housing, almost like you're touching a hot stove. The top of the machine also gets rather warm. The handle I think is ok.

I was just chalking it up to 100deg days plus when I wasn't using the machine it was laying in direct sunlight for the most part.

I have the 9' power cord. I use the 5" backing plate w/ 5.5" pads, would that affect it?

This Thursday as we're buffing out the 2012 Camaro I take some temperature readings using the new MicroTemp MT-PRO Non-Contact Digital Infrared Thermometer to check how hot it's getting.

I'll wait till it's been used to buff out an entire panel.

All the 3401's in our studio are at least a year or older and have seen Newbies and Pro's alike so they are all well broke-in...

Even Adam has put them through their paces...
