1. Do not intentionally use strong wind to detect the flame of a brand lighter, although it is advertised as a windproof lighter, but that still makes the lamp core charring soon.
2. Don't think that the brand lighter is known as waterproof, just let the machine be in close contact with the water, which can't ignite in a dozen.
3. Most of the machines are afraid of oxidation, and accidentally left fingerprints after accidentally playing. For example, when the surface of the brass cabinet is oxidized, wipe it with dilute hydrochloric acid and rinse it with water.
