Anybody know what the Woodmizer HR120 recall details.

I received a Registered letter today that Woodmizer had a retro fit recall on my resaw. It stated something about the fence but I don't know what it is. Does anyone know what it entails. They have a card that when I install what ever they are sending they are going to give me one of the new blades they have.
Sending a registered letter seems serious.

Here is what will have to be done.   Thanks
