How to use:
Step 1: Read the user manual and fill in the butane before using it. The butane lighter contains no fuel due to Safety Regulation and please wait for 5-10 minutes to allow gas to stabilize in the lighter, or the lighter will hard to ignite.
Step 2: Slide up the ignition button to light.
Step 3: Release the ignition button to extinguish the flame and stop fuel flow.

How to adjust flame level:
*Make sure the butane lighter is not operating. *Pull out the adjusting ring at the bottom. *Rotate the fuel adjustment knob to (-)/(+) on the bottom of the lighter to decrease/increase the flame.
*Ideally, the butane lighter's flame height should be controlled at 1.5-2.0CM.
*When you turn off the torch lighter, the flame will still burn for 1 to 3 seconds because there is still butane in the pipe. You can rotate the fuel adjustment knob to the lowest, which can help extinguish the flame and stop fuel flow.
