A case guard is a simple but necessary add on for a 394 in my opinion. These saws get big chunks knocked out of the front of the case a lot, this is cheap insurance.
Remove the nut on the buffer mount stud.

Put the case guard on the stud and install the 2 front mount bolts, tighten the stud nut last. Easy peasy....

While I was in the area I attached the ID tag from my original case half. Retaining rivets just drive in with a punch. To remove a tag without destroying it simply rotate the fasteners counter clockwise with a chisel and hammer. Don’t bother trying to drill them, they’re hard as wood pecker lips.
