Several varieties of refillable butane lighters with flexible necks are available on the market, and all work in essentially the same manner, despite the differences in their appearances. Nearly all models have an adjustable flame--the user can control the length of the flame via a rolling wheel dial on the handle. In addition, all brands have an on/off switch or a trigger, as well as a child safety lock, usually controlled with the thumb. Anyone who has a fireplace, enjoys camping or owns a barbecue should have one of these.
Using the Lighter
Open the casing of the handle. Some models require a small Phillips screwdriver, whereas others have a casing that slides off. Place the battery in the slot, following the directions embossed on the lighter.
Disengage the child safety lock. The lock is spring-controlled and located on the handle beside or above the on/off switch or trigger. Slide the lock forward and hold it in that position until you have created the flame.
Press the on/off switch or pull the trigger, which will activate the electronic ignition and start the flow of gas, creating the flame.
Continue holding the on/off button or trigger to maintain the flame. Some models have a trigger lock; when engaged, the flame will continue to burn until the trigger lock is deactivated or the flame is blown out. To disengage the lock, depress the trigger and release it.
Twist the flexible neck of the lighter to use the flame in tight spaces, such as to ignite pilot lights for stoves, ovens or gas wall heaters. Do not touch the last inch of the neck nearest the tip when the flame is burning, as it gets very hot; however, it is safe to touch the rest of the neck while lit, as it remains cool.
Refilling the Lighter
Select the appropriate nozzle adapter (these come with the refill can) that will fit your particular lighter; different brands require different nozzle adapters.
Place the adapter over the nozzle tip on the can.
Join the nozzle to the butane input port on your lighter. It is a depression with a brass pin inside and should be located in the base of the handle.
Push the can toward the lighter to begin the flow of liquid butane from the can and into the lighter.
Observe the viewport in the lighter to see when the butane level reaches ¾ full--at most--and stop filling.
Store the lighter at least 5 feet from any flame or source of heat. Exposure to heat can make the butane fluid evaporate in the storage chamber, thus increasing the pressure in the chamber and cause the lighter to leak, and exposure to a flame can cause a fire.
Keep the lighter away from small children.
Do not drop the lighter into a fire or lit barbecue; it will explode and fling burning butane fluid in all directions.
Do not put the lighter down or into your pocket without first disengaging the trigger lock; allow the lighter to cool before placing it into a pocket. This rarely takes more than half a minute.
Overfilling the lighter may cause it to leak fluid.
