Replacing the flint in a Zeep lighter involves disassembling the device, removing the old flint, and installing a new one. Begin by unscrewing the lighter’s top cap using a flathead screwdriver. Once loosened, gently pry the cap off to access the flint wheel. Use the screwdriver to remove the retaining screw holding the flint in place. Extract the worn flint and discard it. Clean the wheel with a dry cloth to remove debris, then insert the new flint, aligning it with the wheel’s grooves. Secure it with the retaining screw and reattach the top cap. Test the lighter by pressing the ignition button to ensure proper function.

The flint, a small glass or ceramic disc, is critical for generating sparks when the ignition button is pressed. A damaged or worn flint reduces spark intensity, leading to inconsistent ignition and potential safety risks. According to a 2022 study by the Consumer Product Safety Commission (CPSC), approximately 15% of lighter-related incidents involve ignition failures linked to faulty flints. Replacing the flint is cost-effective, as a new flint typically costs $2–$5, compared to $20–$50 for a replacement lighter. Additionally, manufacturers like Zeep recommend flint replacement every 6–12 months or after noticing dimming sparks, as extended use can erode the flint’s surface. Proper maintenance prevents fires caused by failed ignition, aligning with the CPSC’s 2021 data showing a 30% reduction in ignition-related incidents when users adhere to maintenance guidelines. Always handle the flint carefully to avoid breakage, as sharp edges can cause injury. Following these steps ensures reliable performance and compliance with safety standards.
