Replacing the wick: Update the wick 1-2 times a year. After cutting the wick 2-3 times, it needs to be replaced.
Refilling the lighter: Fill the lighter slowly. NEVER OVERFILL. Before lighting the lighter, remove excess gasoline from the lighter and hands. In case of overflow, do not put it in your pocket or near the skin. If gasoline gets on the skin, rinse it thoroughly with water. Before lighting the lighter, make sure that the gasoline container is closed and there is no spilled gasoline nearby.
