What is the black button thing for on top of Griot's 6" DA orbital?

Hello,
I was just given an old model Griot's Garage 6" DA random orbital. I am curious as to what the small black circle is on top of the unit, in front of the handle. It seems as if it can be pushed and slightly turned, and I hear something moving when I push it, but I have no idea what it is. I don't want to ruin the unit, so I have not yet tried pushing it with the unit on.

Thanks!

Did we take care of your questions?


Any further questions?

Need to add this to my list of articles since it covers why the first generation Griot's polisher doesn't work to actually remove swirls.

Ejector seat?

self destruct sequence? Griots knew it was a POS when they made it, so to save you the trouble of having to beat it into nothingness, they included said button.
