Hey Mark.
What model # do you have. There was a recall on model #s....
model R4511. The recalled saws have manufacturing date codes between CD0829 and CD0837.
Home Depot exclusive models only so it is very unlikely you have it but your picture looks similar and I would hate to have not mentioned it then found out this happened to you....
Hazard: The table saw’s arbor shaft can fail when used with a stacked blade set (commonly known as a “stacked dado set”), which is used to cut grooves. The stacked blade set can be ejected from the saw, posing a potential laceration hazard to consumers.
