Remove the knife jig adgustable stop and the rubber O-ring.

Place the Pivot Collar on the knife jig shaft, and lock with the allen key provided perpendicular to the jig clamps.

I like to return the jig adjustable stop for better control, but many users of the Pivot Collar use it as is.

Clamp the knife in the jig in a regular way, as you do with the stock jig.
