So then... how do you guys avoid kickbacks?
The first thing to do is understand the causes of kickback. There are many, but the most common ones involve the piece moving away from the fence or being pinched between the fence and the blade. In these situations, there's the potential for the teeth at the back of the blade to catch and throw the piece back at you.
To avoid kickback:
Make sure the fence, blade, and miter slots are properly aligned
Use the splitter supplied with the saw or a suitable aftermarket alternative
Keep the piece being being cut against the fence at all times!Use the miter gauge or the fence, but not both at the same time
Use a featherboard, when appropriate, to keep wood against the fence and down on the table.
Grip Tite's magnetic featherboards are a really slick product in this regard. If there's a woodworking show in your area, their demo is pretty darn impressive.
Use a special jig or fence when working with laminates or other very thin stock that can slide under a normal fence. Invariably, the piece is sliding under the fence the back is also skewing into the blade, inviting kickback.
I would also suggest that you need to set the blade at an appropriate height for the cut being made. Different people have different opinions of what constitutes "appropriate". I would probably tend to run the blade a bit higher than most; the lower the blade the more teeth are buried in the wood at any particular time and the easier it is for kickback to happen if something goes wrong.
