Hi
Welcome to the Forum
Before I start to answer your question, it would be helpful to know a bit about how experienced you are. Dado sets are notorious for playing a part in very nasty accidents.
This may be presumptuous of me, but my guess is "not very". I don't mean that nastily, it's just that that saw is a very small, very basic machine and if you were very experienced I'd expect you to know the answer to your own question!
OK, the short answer is No, not a cat in hell's chance. But that's not very helpful, so let's explain why.
Stacked dadoes are many times heavier than a standard blade. That means that there is more momentum. On a big machine, that increase in momentum is relatively small compared with the momentum of the motor, but on a tiny machine like that it would make a considerable difference, resulting in the saw taking longer than 10 seconds to stop. That would put it outside the rules for braking times.
Secondly, the saw would need a long arbour and arbours are short specifically to stop us from fitting dadoes to inapproprate machinery.
Thirdly how do you propose to guard a dado stack? It's quite possible, but not easy.
So there are 3 very good reasons why you shouldn't even attempt it, and I'm sure I could think of many more.
So now let me try to be encouraging and constructive.
First of all, ask yourself why you want a dado set. For cutting housings? Use a router and jig. For cutting grooves and rebates? Use a router with a fence or a bearing, as appropriate. It's much safer, easier and quicker for small runs, if you take into account the setup time.
If you are hell bent on using a dado set, you need to consider upgrading your machine. Almost all consumer-grade tablesaws sold in county come with a short arbour. On some machines this can be replaced with a long abour. Several of us on here have the Xcalibur cabinet saw from Woodford's. It's one of the few that will accept a longer arbour. But it is not CE rated, so you couldn't use it legally in a commercial business, even if you guarded it properly and used jigs. But it is a superb saw, all the same and you should consider it as your most basic option. They go up from there, and as you have discovered by Googling it, it's not pocket-money prices.
I suggest that you find other ways to achieve your ends. There is nothing that a dado set can do that can't be done more safely and cheaply with a router. If you do want to see how to use a dado safely then follow the link in my footer and read the blurb about Workshop Essentials Volume 10. It might just save your fingers.
