adjust the wick case like the letter (M) to fit your glass so that it does not slip and the wick remains centered, about (1 cm) below the rim of the glass.
Insert the wick into the tube, leaving about 3 mm -5 mm wick.
Fill it with vegetable (Only) oil (olive oil is best) until it reaches the middle of the wick ( Do not use Parafinne Oil).
When the wick absorbs the oil, you can light it.
If the lit part of the wick is too large, it will cause smoke and higher temperatures. The short wick will have a small and soft flame and will burn clean.
Safety Tips
Do not burn oil lamps unattended, children are forbidden to use it.
Extinguish the flame before removing the wick case and adjust the wick.
Remove any flammable materials up close
