It came with the hardware already installed on the arbor. All I had to do was remove the nut and one washer. The inside washer is fixed permanently. I had the larger side of the outside washer facing the blade. I also made sure both were clean, flat, or at least as much as possible because they had rolled edges, and otherwise all looked normal. But for reasons I never found out, it cupped the blade when tightened, so I returned it. The girl in the hardware area said others had been returned for the same reason.
So, instead of another Kobalt, I left and went to Home Depot to look at the Ridgid R4512. I was really close to getting it, but it just seemed too big for the space I have available, a 13x22 garage that has all my other machines, and also contains the washer/dryer and water heater. Plus, I just really like the idea of a portable saw for work at home and away from home. I ended up getting the Ridgid R4513 portable saw. It is about the nicest portable I ever did see. The miter gauge alone is impressive, and I may start using it for the first time ever. The fence is much nicer than my old saw, self squaring, and was near perfect out of the box. It was 1/32 off in distance from fence to blade according to the built in ruler, but I adjusted the indicator by setting the fence an exact distance from the blade and double checking it with a steel ruler, then moving the indicator to reflect that measurement on the ruler. The blade on this saw came preinstalled so all I had to do was check it with a square. It was good. I believe I have a better saw now than what the Kobalt was. I absolutely hated knowing it costed within $30 of the price of the much nicer R4512, but shop space, portability, and just shear ease of movement all take priority over having the most saw for the best price. I am still happy though, because this saw feels much better to me than other portables have. It doesn't feel flimbsy or rickety at all. I feel like my abilities will increase simply from having such a better saw than I've had up until now.
I will run a few yards of wood through on the factory blade to see how it goes, but most likely I'll put my Freud blade on it after that.
