Refuel
Regular lighters usually use some kind of lighter fluid, while Zippo lighters use butane. They are built with the ability to be refilled once the butane is gone. Zippo recommends they be refilled using Zippo brand butane. Turn the lighter upside down and insert the nozzle of the butane can into the hole. Press the nozzle down a few times, releasing the fuel into the lighter.
Replace The Flint
When the flint on your Zippo goes out, it will have trouble creating a spark and keeping the flame lit. To replace the flint, turn the lighter upside-down and remove the small screw at the bottom. Pull the flint wheel out of the top of the lighter. Place a new flint into the lighter and into the tube in the middle. Replace the screw tightly.
Vapor Lock
Vapor lock happens when you refuel your Zippo improperly. This allows air inside your lighter instead of butane. The lighter will not light or spark. Press a small screwdriver into the valve in the bottom of the lighter, draining all of the air out. Be careful to point the lighter away from your face.
