is this normal ??? What can i do to make it better

You mean, other than an overhead guard?

Note that you need some space for the air to get *into* the cabinet...at least as much total area as the dust collection port. The trick is to have the air coming in through places where there isn't dust trying to go out.

One of these days I'm going to get some chunks of magnetic sign material and use them to block off the slots for the front adjustment wheel.

I will assume by "wholes" you mean holes and that's your problem. Everywhere that air can exit the saw cabinet, dust will follow, so your only solution is to seal as many as you can except for the dust collection port. Tape on cardboard, sheet plastic, whatever works and then you should see some improvement.

Yes, you're right, but even a zero clearance insert should allow sufficient air flow to stream dust into the cabinet and then into the dust collector port. As well, most saw blades (at least combination blades) have gullets which also allows a substantial amount of air flow to be directed into the cabinet.

Thanks guys, you already answered my first question. obviously it is happening. I used the saw and paid more attention to where actually the saw dust was getting out and the worst offender is the blade pushing it out into the guard. It looks like I would have to implement some sort of DC tube to the guard or perhaps buy one. do you know if you could change the guard on TSC-10HB ?

Depends on how much you want to spend. Here's a few examples.

Brilliant idea... consider that one stolen.
