To light a kerosene lighter, first unscrew the fuel cap counterclockwise to open the valve. Prime the lighter by pumping the handle 3-5 times to fill the fuel chamber. Wait 30 seconds to allow fuel to settle. Light the preheated wick with a match or lighter, holding the flame near the top until the flame stabilizes. Never attempt to light a cold lighter, as this can cause uneven burning or failure. Always store kerosene lighters in a cool, dry place away from children and flammable materials.

The steps above prioritize safety and functionality. Kerosene requires precise priming to prevent fuel leakage or flashback, which can lead to accidents. A 2021 study by the National Fire Protection Association (NFPA) found that 12% of home fires involving portable heating devices were linked to improper fuel handling, emphasizing the need for correct priming techniques. Additionally, the Consumer Product Safety Commission (CPSC) advises that 60% of kerosene lighter malfunctions result from failing to wait 30 seconds after priming, allowing fuel to distribute evenly. Kerosene’s high flash point (121°F/50°C) compared to butane (-105°F/-64°C) means it demands slower, controlled ignition to avoid sudden surges in flame intensity. The NFPA also notes that 85% of kerosene-related injuries occur when users attempt to light the lighter while holding it, increasing spill risks. Proper handling reduces these risks, aligning with CPSC guidelines that recommend using a stable surface and avoiding sudden movements during ignition. Adhering to these steps ensures safe operation and extends the lighter’s lifespan by preventing wick clogging from unburned fuel.
