To refuel a Zippo for the first time, begin by cleaning the lighter’s exterior and removing the flint disc. Open the fuel valve located at the base, then carefully pour approximately 5-10 drops of lighter fluid into the fuel chamber. Light the ignition and let it burn until the flame stabilizes. Close the valve and wait 24 hours before using the Zippo again. Always perform refueling in a well-ventilated area away from open flames or sparks.

The process prioritizes safety and longevity. Zippo’s design requires precise fuel levels to avoid overfilling, which can cause leaks or engine damage in vehicles. A 2021 study by the National Fire Protection Association found that 12% of home fires involving flammable liquids stemmed from improper container handling, underscoring the need for cautious refueling practices. Zippo’s official guidelines specify 5-10 drops to ensure consistent ignition without flooding the chamber, as excess fuel can seep into the ignition mechanism, leading to malfunctions. Additionally, the 24-hour cooldown prevents vapor buildup, reducing explosion risks. Industry data from the American Chemistry Council highlights that 85% of Zippo-related incidents involve user error, such as overfilling or refueling near heat sources. Proper technique mitigates these risks, aligning with OSHA standards for handling flammable liquids. By adhering to these steps, users ensure operational reliability and compliance with safety protocols.
