Service Bulletin: SB 147.1
Subject: Bottom Finish Assembly — Ramp Style
It has come to our attention that the four bolts (SHCS 5/16-24 x 7/8) that bolt into the front plate slide (tooling) are coming loose. To guard against this you will need to remove the bolts and you MUST use removable LOCK-TITE on the bolts and re-assemble them.
We highly recommend Perma Lok (Nut locking) MM115.
