Like a fine Swiss watch, Dunhill lighters are precision pieces that offer a combination of elegance and function. These coveted lighters typically retail for several hundreds of dollars, but require no special skill to maintain and operate. Your lighter requires a combination of fuel, spark and oxygen. While oxygen is plentiful, your lighter contains a finite amount of fuel and flint, which will need to be replaced periodically. Adjust your lighter's flame to suit your personal preference.
Open the lighter's lid. Depending on the model, look for either a screw or flat metal slide. Both designs cover the flint chamber.
Turn the screw counterclockwise, and remove the screw and spring. Alternatively, for models with a flat metal slide, push back the flat metal slide until the flint chamber pops open.
Rotate the Dunhill lighter so that the flint chamber is pointing down above your hand. Shake out the old flint into your hand, and discard.
Drop a new flint into the chamber. While other brands of flints may work, Dunhill recommends use of its own flints, which are designed especially for Dunhill lighters. These flints create greater spark while also reducing wear upon the flint wheel.
Turn the Dunhill lighter upside down to expose the filler valve at the bottom.
Look for a slotted screw or cap on the base of the lighter.
Press down on the cap and turn counterclockwise to remove. For models with screws, grip the knurled sides of the screw and turn the screw counterclockwise to remove. If the screw proves too difficult to remove by hand, use a coin. Some models will have no valve cover at all.
Insert the nozzle of a fuel filler bottle into the aperture. Gently squeeze the bottle until the cotton wool is saturated or drops of fuel escape from the valve.
Replace the screw or cap, where applicable, atop the filler valve, and tighten.
Raise the lighter cap. Using your thumb, rotate the roller in a clockwise direction once. For models with a safety catch and ignition lever, align the safety catch with the flame symbol atop the lighter, then depress the ignition lever.
Close the cap to extinguish the flame. Alternatively, for models with an ignition lever, release the lever.
Determine whether flame height is suitable. Normal flame height is approximately 25mm. To adjust flame height, proceed to the next step.
Determine the method for adjusting flame height. Your model will include either a knurled wheel on the back edge of the lighter, a "D-ring" at the base, a slotted cap at the base, or a wick.
Turn the knurled wheel up to increase the flame. For models with a D-ring, lift the D-ring and turn it counterclockwise to increase the flame. For models with a slotted cap, use a flathead screwdriver or small coin and turn the cap counterclockwise to increase the flame. For models using a wick, use tweezers to raise the wick.
- Always fill your Dunhill lighter away from any flame.
