Well, first of all, at only 6 months, it really shouldn't be making any noise. But, with that said, everything that comes from off shore is being built as cheaply as humanly possible and in some cases no grease or lubrication has been added prior to shipping. It's just a sad fact. Your saw is very similar to all the saws of that same design. In my case, when I bought my first saw it was a used Dewalt 788 and I had no idea how it had been maintained. So after watching a very wonderful set of how-to videos done by Bob Brokaw through Gwinnette Woodworkers Youtube site, I decided to tear my saw apart and inspect and lubricate all the bearings. And there are many. I would imagine that yours is no different. So, the short answer to your question is, yes, take it apart and inspect it. But, first try to locate those videos and watch them. They won't pertain to your exact saw but should be close enough that you can get an idea of what to do and how to do it. Also, I might add, at only 6 months of age, it should still be under warranty. If you bought it from Home Depot, I'd suggest taking it back and getting another saw. Or have them send it in for repair. Wen has a very good reputation for standing behind what they sell. I've had good luck with them regarding my air cleaner when the remote control went south. They send me a new remote and the updated circuit board. Best of luck. I'm sure it will all work out.
