Okay check the o ring that the bottom of the 510 pin has that big red one that sits I the plastic, clean every thing make sure juice is not on any battery contacts, and a third thing I did was losses the button screw a little bit mines firing hard as when I got it after I did those thing.Is anyone else having issues with the firing button? My one doesn't always fire when I press the button unless I press it a certain way or push it right down with a fair bit of force to make sure it makes contact & even then I don't think it's making a good contact because it's not hitting as hard as it should. I'm finding it really annoying, I've pulled it apart a couple times now everything is clean & looks good. I'm not really sure what else I should try.
P's that owing has to be seated in the Grove and a little bit of your 510 can be seen.
I just remembered also make sure the Owings are on the top of your refill bottle.
