Today my 510 started being really, really hard to drag (low air flow). It's better now:
-- I blew out the atomizers (just swapping atomizers didn't seem to help)
-- I kept the cart more filled with juice
-- I used fully charged batts -- switched to full charged batts before the "dead light flash"; switched often.
One of those things helped, or maybe a combo of them all. But I was very disturbed that the thing was so hard to suck. (I carry it with me everywhere, now carry juice too; I vape A LOT).
What causes "hard drag"? Most commonly?
The other hardware issue is the screw connections (atomizer->batt) seem hard to screw.
I've been wiping them down with a paper towel until no more black crud came off, every night, but that's all. Is there more I need to do? (Lube the screws? They seem that hard to screw together.)
I'm "only" on day 12; my maintenance has been minimal. Do I really need to take the atomizers off at night and store them a certain way? How often should I be cleaning the connections, and with what?
