Open up windows if you’re refilling your lighter indoors. Turn on a fan to improve air circulation in the room.
If you’re working outside, make sure you use a surface that’s clean and dry so you don’t get any dirt or moisture in your lighter.
If you recently used your lighter, wait at least 30 minutes before you refill it.
Some butane lighters come with a special key to turn the adjusting screw. Your lighter may have a wheel to adjust the flame height instead of a screw, so you don’t need to use a screwdriver to set it to the minimum setting. Don’t force the screw. If it isn’t turning anymore, it may already be set to the minimum setting.
Any air or gas left inside the lighter can prevent the butane from being injected into it and can break your lighter.
Holding the lighter upside-down also means you’ll need to hold the can of butane upside-down when you refill your lighter.
Give the can 5-6 good shakes to prime it.
Depending on how empty the lighter is, it may take 2-3 bursts to fill it. Some lighters have a gauge that shows the fuel level. Check the gauge to make sure it’s full. Don’t overfill the lighter. As soon as it feels full, stop adding butane.
Keeping the lighter set at the minimum setting can make it harder to start, especially if it was completely out of fuel.
Adjust the flame height to your desired setting. If the lighter doesn’t produce a flame or the flame is really weak, you may need to add more butane.
A secure drawer is a safe place to store butane. If you have small children, be sure to store the butane in a hard-to-reach area.
