You need to gently blow air from your mouth at top of atomizer cone while holding a tissue or napkin on bottom where threads are located. Your blowing out primer that usually comes in these atomizers , this primer can be harsh if vaped and burn. It will make flavors taste horrible while giving you a bad burning sting to the back of your throat. This step is important!!! Once batteries are charged go ahead take battery off charger and screw cone shaped atomizer down onto battery. Not to over tighten!! Plastic tanks come with the kit, one end is flat for mouth other end is round with small cap. pop cap off bottom of plastic cartridge and simple fill tank with eliquid.
