I've been sort of using my press as a single-stage up to now, or using the auto-index to quickly move between 2 or 3 stages. I've primed about 100 .40 cases but I had my son insert the primers into the cup individually (thank heaven for small hands).
I can't get the safety prime arm to stay lined up with the primer ram. When I hold the SP arm to the left (basically holding down the right side of the tabs on the top of the SP) it works. but it takes two hands. If I let go of the SP the right side lifts out of its recess (I guess from the "spring" tension of the little plastic spring thing).
Any ideas?
Thanks for asking our advice.
Sounds like you don't have the thing positioned correctly.
If you take a screwdriver and use it to swing the primer dispenser toward the primer cup (use a tool rather than your finger so you don't apply any lateral or vertical pressure inadvertently). If it doesn't line up perfectly, adjust the positioning of the mount so that it does.
I understand there are videos of how to do this properly, but the above method is how I did it and I have had no problems at all getting the primers into the cup.
Well, that is not exactly true. When I started, I needed to refine my technique of operating the little "pez dispenser" part. I had to learn to apply
only forward pressure with my right thumb until the dispenser was fully engaged with the cup, and then apply
only straight downward pressure with my forefinger to expel the primer. It works 100% now.
If that does not work, do a search for loading videos on how to install and adjust the LPS.
Good luck,

edit: the little black plastic spring thing in the mount is only there to prevent the device from coming out of the tray part of the mount. It should not be actively doing ANYTHING when the device is in use. In fact, if it were gone, the operation of the primer device would be affected not at all. If it is compressed, your Safety Prime device is probably not fully inserted in the mount, and if you can reach the primer cup with it like that, the mount is definitely not positioned correctly. (This is all without benefit of a visual, so take that into account.)
