I don't follow the marking part, they are stamped with a logo on one edge. I just keep that logo in the same orientation as I rotate them (only done it once). But I removed them a row at a time so I could clean the seats, and then replace the cutters. I torqued the to the proper spec with a little screwdriver type torque wrench (45 inch# I think). At one point I rotated them what I called "inside out". My reasoning (maybe faulty) was that the center most cutters receive most of the use, so I moved the outside cutters into the center, and the center ones to the outside of the cutterhead. Can't say with any evidence that it extended the life of the cutters...but I do know at the time I did it it seemed to make sense.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.
