Upon start-up, my bandsaw lets out a squeal lasting about a half second, then disappearing. The mfg rep told me it is from a tiny bit of slack in the belt and nothing to worry about. In fact, he said a belt that's too tight will put more strain on the bearings than necessary, and it's better to err to the side of a tiny bit of slack. I tightened up the belt a little and it went mostly away, but now it's back.
This is a new-ish saw, so could it be just the belt stretching a little as part of the break-in, and should I it tighten it again, or not worry about it?
Maybe there is a different root cause than the belt tension?
The saw cuts well and I'm not experiencing any power issues. This is a S500p (fka MM20) btw.
Thanks, Edwin
P.S. I recall back in the day sometime automotive belts would squeal when they were dry and they would apply a dressing to resolve it. This raises another question - is it a good idea to dress the belt and maybe the tires from time to time, especially if you live in a dry climate?
