Adjustable:
Flame adjuster is under the bottom of the lighter (the big wheel surrounding the filling hole and NOT the small screw), please follow the "+" and "-" sign to turn it.
Flame height need to be re-adjust to desire level because butane pressure in the fuel tank reduces after a period of use.
How to Refill:
1.Set flame adjuster near (-) position.
2.Release the remaining gas before refilling (use a small screwdriver to press the filling hole slightly to release the gas).
3.Put lighter upside down, shake the gas bottle first and press it 2-3 seconds for 3-4 times (please choose long nozzle gas can).
4.Shake the lighter for several times after filled and adjust flame before first ignite.
Tips:
Lighter will not ignite at the lowest setting as there is no butane pressure.
Keep Away from children, face, body or any inflammable things.
