I did a quick look on the web (Emerson Site) and did not notice any specification for the limitation of width for a dado blade. I would suspect that since it is a "Job Site" class saw, the saw is not designed for a dado.
There is an easy way to tell if the saw might accept a dado. Install a normal blade on your saw. Use the arbor washer and nut and tighten as normal. Now measure the amount of arbor threads that stick out of the nut. If there are about 3/4" or more of threads, you might be able to run a dado.
Next take a 1", 1/4x20 screw with a nut and lightly clamp the screw to a gullet in the blade. The screw should stick out in the same direction as the threads that you measured above. With the saw unplugged, turn the blade by hand. Does the screw bind or rub on any part of the saw? Or Did a part of the saw knock the screw off of the blade? If the answer to both is no, you may be able to run a dado blade in this saw. (The manufacturer may advise against it, however.)
Be aware that regardless of the HP numbers, most job site saws are a bit anemic to be running a dado blade. If you are able to fit a dado blade on this saw, I would suggest using a 6" dado blade.
A throat plate can be easily made for most saws with removable throat plates. Also, a zero clearance throat plate can be purchased and used as a dado throat plate. Just use the same procedure that you would use when making a ZC throat plate.
Use the right tool for the job.
