Here is the manual; not much help BUT i would recommend disassemble, clean, and reassemble properly to see if it helps, also focus on cleaning the POGO pins. Also make sure that the auger can compress freely to trigger the anti jam. I would print the manual if you haven't done so also; it is a good disassembly reference
I'm not sure if it's adjustable, it's just supposed to 'work'
I wasn't sure if it used eyes or a pressure switch in the neck; the manual says eyes though so I'll assume it's true. Look carefully when you have it apart and look for those eyes
Minor update: I turn mine on with no paintballs and it spins fast, then starts pulsing and the jam light comes on and it keeps pulsing
Now with paint, it works normally but the jam light is on constantly
If I pull the bottom tray and lick the pins then put it back, I get the green light then it goes red again
I may be using low batteries however
