The red bolt sets the tension on the ball bearing the Prolock, it is adjusted at th factory and should not be turned. ?This is what the Owner of Prolock told me at LIGNA when we bought a batch of pro locks for our super spindles.?

The instructions I received with mine are instructions for the saw blade lock.? Does anyone know if we are to do anything with the red flat blade screw?

?Thanks to Michael Marsico, received?ProLock shaper spindle locking caps today. FWIW, there is an icon on top to indicate that the allen set/grub screw is the one to tighten.
I did not know how this gizmo works. The split screw that is hand tightened has a dome shape on the underside.
The cap has the negative profile. Once the screw is hand tightened I assume the two profiles marry/merge. Now as the allen grub screw is tightened the 2 halves of the screw spread. This should impart a downward force on the lower cap.
At least that is what I am theorizing after looking at it.
?Thanks for the replies, it took a pair of pliers to break the knurled screw free, all is good now
