I have the same saw and have had it for over ten years. Mine doesn't do that. I do give the round slide a squirt of WD-40 every time I go to use it. Makes the tray slide real easy.
Sorry you had this experience, but also makes me feel a bit better knowing others have been screwed too haha.I had a similar problem shopping at Amazon, new merchandise which turned out to not be new. I won't shop there any more. They sell stuff from all sorts of sources and don't generally tell you where your purchase comes from. They do make an effort to resolve issues. I'm old fashioned and detest 3rd party sales.
