1. Steps to replace Dupont lighter flint

1.Preparation: Make sure the lighter fuel is exhausted to avoid accidental ignition during operation.
2.Dismantling the flint bin: Using Dupont's special tool or a small screwdriver, turn the screw on the bottom of the flint chamber (usually located on the bottom of the lighter) counterclockwise.
3.Take out the old flint: Gently pour out the remaining flint chips and check whether the spring is intact.
4.Load new flint: Place the Dupont original flint (model needs to match) into the warehouse to ensure that the flint and spring are in close contact.
5.Restructure lighter: Tighten the flint chamber screw clockwise to test the ignition effect.
2. Precautions
• Be sure to use original flint (such as Dupont Ligne 2 special flint), as inferior flint may damage the spark wheel.
• If the spring loses its elasticity, it needs to be replaced simultaneously.
• Avoid using excessive force during operation to prevent thread slippage.
