@TWheels Must have been a disappointment that it didn't go together right off the bat. I imagine it's a repack of a returned saw. CPO has a pretty good reputation with these things, so I imagine it will be taken care of. If not, this Forum will need an explanaton. That kind of thing is a reputation killer.
You may be surprised at how often you'll prefer using the table saw rather than the sliding miter. When you get up and running, get a blade or two, they will really affect your work. I particularly love the Freud Glue Line rip blade, although I use it for crosscuts too. Buttery smooth cuts every time.
I have also switched (almost all) narrow kerf blades for full kerf (1/8th thick) blades. They don't deflect as some of the narrow ones have when cutting mitered ends, as in picture frames.
If CPO won't fix the saw, don't be afraid to return it. I was never able to get my first small table saw to cut right, but waited too long to return it. The blade stop is really nice, but you aren't married to it. Safety on a table saw is far more about how you behave and move around the saw and handle your material. I still think-through every cut I make on my saw, anticipating every move, and planning. Saws are not what chops fingers off, careless woodworkers do.
