I was asked to look at a Bosch 5412L crosscut miter saw which had a blade guard that was not retracting smoothly. The operator had to manually get it started the first couple of inches. A dangerous situation especially since it was used in a school shop.

I found a few references on the web to this problem with no clear solutions.

After some tinkering I came up with this idea. I attached a 1.25” O.D. flat washer using aluminum pop rivets to the linkage at the point where it was hanging up on the bearing. This change resulted in a smoother transition across the arm and the guard now retracts easily.

I added a pair of flat washers behind the bearing so it is centered on the linkage and 1.25” washer.

In my case, the spacer was missing and replacing it fixed the problem. (Part #: 2610911850 .
Since I was at it, I replace also the missing washer (Part #: 2610911599 and the screw that was damaged from running without the spacer (Part #: 2610911598
