Butane Lighter: Refilling it?

[godfather]

you do know how to properly bleed it,don't you??...

Yes, I read up on it a little more last night:

"Always bleed your butane tank before refueling. Bleeding your butane tank releases all the air that has been trapped in the tank and any unused butane that hasn't been used.

Again, some common sense really works here. Butane is a gas and cannot be transferred into your lighter from the butane canister without some form of propellant. The cheapest propellant is compressed air. Eventually, if you don't bleed the air out of the lighter's fuel tank, then that air will displace the amount of butane fuel the lighter can hold. Consequently, your lighter won't light or will "sputter" and the less it will light. Remember, air doesn't necessarily ignite by itself. The proper mix of butane and air works perfectly every time.

Here is how to bleed your butane tank on your lighter. Turn your lighter upside down, and using a small screwdriver or some other small metal device (never use a ball point pen because the ink will blow out all over the place), depress the refill valve on your lighter. Let all the air and butane escape.

Use some common sense here. Always bleed your butane lighter tank away from any flames and people and please do not smoke when you are doing this. You could catch something on fire.
If your butane lighter has a flame adjustment valve, turn the valve to its lowest level. Sometimes lighters have a "memory" and if you do not turn the lighter adjustment valve down when refueling, the lighter might "remember" that this is the lowest setting. Your adjustment valve may not work properly and the flame may be too low for you."
