The LR 306 User Guide This guide will continuously be updated, but this is going to serve as our baseline. What you should know: When using a new LR 306 for the first time, it is important to prime the atomizer properly. Cisco LR 306 atomizers come with NO PRIMER, therefore special care must be taken. Priming is done by dripping 4 to 5 drops directly onto the atomizer coil, waiting about 60 seconds, then dripping another 1 to 2 drops. After this is done, you are ready to take your first drag. Do not press the button before this point. These atomizers come with no primer because a) So you don't have to clean it out & b) Some people are sensitive to primer. As with all LR atomizers, do not use with any batteries rated higher than 3.7v. LR 306 must not be dry burned to be cleaned. This will damage the atomizer. Instead, soak in grain alcohol if cleaning in absolutely necessary. Alternatively, try blowing out excess e-liquid from the bottom into a napkin. LR 306 atomizer must be kept wet at all times. The moment you detect that your e-liquid is almost finished, drip at least 2 more drops. The LR 306 atomizer shares the same threading with the 510. It will fit on any device a 510 atomizer will fit on. Do not use LR 306 (or any low resistance atomizer) with batteries rated less than 450mAh. Not only will it will damage a standard e-cig battery, but you will not get the most out of low resistance. These atomizers can take 24-48 hours to fully break in, depending on how often you vape. It is not uncommon to feed these atomizers up to 1ml of liquid within the first hour of usage during the break in period. The amount of liquid needed will decline after the initial 24-48 hour period. Some leaking from the bottom of the atomizer may occur during this period. Drip tips: Do not force Version I Colored Translucent Drip Tips to the base of the atomizer. Press them down until you feel some resistance, then do not press any further in order to avoid any cracking or splitting. Version II Colored Translucent Drip Tips CAN be pressed to the base of the atomizer without worrying about cracking or breaking them. V2 is a new and improved design over V1. -> Enjoy this atomizer. With a drip tip, many find it to be their most enjoyable vaping experience to date.
