Welcome to LumberJocks!

Sorry to read about your kick back event. Never any fun.

Hard to tell what you did wrong? This article might help you figure it out:

There are many more articles on WWW about avoiding kick back, if this randomly selected one does not make sense to you.

For me, the two things that stopped 99.99% of kick back were:
1) ALWAYS use a splitter, or riving knive on newer saw
2) Never cut across the wood grain with board wedged between fence and blade.

Best Luck figuring out what happened.

Cheers!
