How to filling a butane lighter

To fill a butane lighter, you can follow these general steps:
1. Locate the refill valve: This is usually found on the bottom of the lighter or near the base. Look for a small hole with a screw or pin in the center.
2. Depressurize the lighter: Before refilling, you need to release any remaining gas from the lighter. You can do this by using a small screwdriver or other tool to depress the valve and allow the gas to escape.
3. Shake the butane can: Shake the butane canister to ensure it's well-mixed.
4. Align the canister: Hold the lighter upside down and align the nozzle of the butane canister with the refill valve.
5. Press and hold: Press the butane canister nozzle down into the refill valve and hold it there for a few seconds.
6. Wait a minute: Wait a minute or so for the butane to settle into the lighter.
7. Test the lighter: Test the lighter to ensure it's properly filled and working correctly.
