How to Refill Your Line 2 Lighter

What You’ll Need:

• S.T. Dupont Red or Yellow Butane (depending on your model)

• Flat, stable surface

• Clean cloth

Steps:

1. Turn the lighter upside down and locate the refill valve.

2. Remove the protective refill cap (if present).

3. Match the refill color to your lighter model:

   • Red Butane – Standard Line 2 models

   • Yellow Butane – Ligne 2 Torch (rare variant)

4. Insert the S.T. Dupont gas refill nozzle firmly into the valve.

5. Press down and hold for 4–5 seconds.

6. Let the lighter rest for a few minutes before use to stabilize the gas.

Important: Always use genuine S.T. Dupont refills to avoid damaging the lighter or voiding your warranty.

How to Ignite the Lighter

1. Flip open the cap using your thumb—listen for the iconic “ping.”

2. Roll the ignition wheel downward to create a spark.

3. The flame should ignite smoothly with minimal delay.

Troubleshooting:

• If the flame doesn’t appear:

  • Ensure there is gas.

  • Check the flint.

  • Confirm the ignition wheel has proper resistance.

Adjusting the Flame Height

1. Turn the lighter over to locate the flame adjustment screw.

2. Use a small flathead screwdriver:

   • Turn clockwise to lower the flame

   • Turn counterclockwise to raise it

3. Make small adjustments and test ignition after each turn.

Replacing the Flint

When to Replace:

• If the lighter no longer sparks or requires multiple strikes.

How to Replace the Flint:

1. Locate the flint screw at the base of the ignition wheel.

2. Unscrew it carefully and remove the spring.

3. Remove any remaining flint dust.

4. Insert a new S.T. Dupont flint (gray).

5. Reinsert the spring and screw it back into place.

6. Test the spark by striking the wheel.

Tip: Only use genuine S.T. Dupont flints to ensure consistent performance.
