You might also check, the saw stop is bad about saw dust gathering in the rear of the rear posts. Look in the Manuel, it addresses that issue. I found that a vacuum is better to remove it than the blow gun (compressed air)

the first one , saw stop I owned (early model). It had a door on the right plus I think another. This later saw has a Mickey mouse plastic door (cover) on the left. I regret selling the first SS due to moving. I think it was a better saw than this later model. I also had a Powermatic 66, advertised both, not one hit on th PM 66. I could have sold 20 saw stops. I just couldn’t afford to move both. Moved to NY from Colorado, PM66 sold here in NY really fast. The PM 66 in my opinion is a better saw, larger top, heavier trunnions it just doesn’t have a rifling blade and the hotdog electronics. O’well I got older but not smarter I guess.
