We have a 2005 Fadal EMC, when getting into the 6K+ RPM range, I can hear what I can only describe as ringing - sort of the ringing you'd get in your ears after a loud concert coming from the spindle. I cannot honestly recall if this has been on-going, but I am only noticing it recently, making me thing it is only recenty it started to occur.
We have 3 months of warranty left - is it time to get a tech over to look at the bearings ? could somthing else be the cause ?
Thanks for any input.
