How to adjust adjustable rockers?

Yeah you need to make sure the nuts don't come off! The factory arms are not set up for plain nuts and they will come loose sooner or later. And if they come off...... IDK what will happen but it might not be a good thing..............
I run my anti pump-up hydraulics at .020 preload, and don't readjust until it's worth my time to go in there; it seems to run best when it clatters a bit lol.
I'm just lazy that way. It's been clattering since about 2005, lol.......
