How to refill a butane lighter

Burping / Bleeding your lighter, is when you get all the old fuel and air out before refilling it with new butane. This is done to help prevent your lighter from sputtering or flickering thus giving you the best light possible. To begin, turn down your lighter, or turn your lighter’s lock on, if you have one. This is just to prevent yourself from accidentally turning on the torch while you’re working on it. Next is to locate your lighter’s refill hole / port. This is typically found on the bottom of your lighter. Flip your lighter upside down and with a small tool, such as a pen apply pressure to the refill hole until you hear it sputtering or until you feel cold air being released. It is best to avoid sharper objects like knives in order to avoid any possible damage or scratching to the refill hole.
