So it's a 3-piece 510 auto kit. Cool. The little how-to page at the site isn't that bad:
How do iVAPE?
Here's a short Joye 510 manual:
Electronic Cigarette Instruction Manual
Overall, either/both of the above, plus:
-The atomizers may have primer on them. Before first use, hold a tissue over one end then blow through the other to remove any.
-With an automatic battery, be careful to not overfill cartridges or cartomizers. At the end of the day, or before putting a battery on a charger, it is a good idea to wipe the battery connector to remove any liquid that has gotten into it. If using cartomizers, blow through the cartomizer onto a tissue, then wipe the battery contact, before putting the cartomizer on the battery.
-Drink lots of water. Vaping tends to dry you out, causes hoarseness.
-The strength of liquid (mg/ml of nicotine) needed varies from person to person. A typical pack-a-day full flavor cigarette user will likely need 24 mg/ml strength liquid to stop smoking, though some may need weaker (16-18 mg/ml) or stronger (30 - 36 mg/ml); more rarely a full strength smoker will need to drop to 12 mg/ml strength. A lights smoker will typically use 18 mg/ml liquid, with some needing 24 mg/ml and others needing 12 mg/ml; more rarely a lights smoker may need 6 mg/ml.
-Do a slow inhale, into the mouth, then into the lungs
should be enough to get most people going.
