I've had this drum sander for about 4 years and it's performed admirably all that time.
BUT, in the last week or so when I've been running it for 4-5 minutes it starts to emit a howling that sounds an awful lot like a bad bearing.
Does anyone have this sander and have you had occasion to change the bearings? Is this a difficult fix or should I be contacting the seller to make the repair.
I couldn't find this particular issue addressed in the archives and I'm hoping someone may have the answer.
Thanks for your help.
Doug
