Hello DelFit,
I wonder if you could enlighten us here.
We own an elliptical machine, not Precor's, that sprinkles black dust on the machine itself and the floor mat. We are now very concerned because it looks like tiny particles of metal that we could end up inhaling while breathing heavy on the elliptical. We know the disc has a tiny magnet but that is for reading the speed and feeding the data to the console. As we assembled it, there was an electrical wire (for the data feed) and just a cable which I think was for the resistance. We don't exactly know where the dust is coming from.
While you are dealing with an elliptical, bicycle or any other similar fitness equipment, has there ever been a case where the disc area sprinkles black dust, maybe a piece of magnet or metal? Has there ever been a case where the pedal area spews black dust?
Regards,
Bonnie
