In the early 1900s, Alfred Dunhill began a new business that supplied well-appointed accessories such as pipes, watches, and cigarette lighters to well-heeled gentlemen. Dunhill expanded by opening stores in the United States in the 1950s. According to Dunhill, its lighter was the first that could be held and operated in one hand. The luxury lighter is still being offered by Dunhill as of 2010. Keep your Dunhill lighter in top operational condition by giving it periodic service.
Keep your Dunhill petrol lighter filled with fluid. Turn the lighter upside down and keep the cap closed. Turn out the filler screw in a counterclockwise direction with your thumb and forefinger and place it aside. Pour lighter fluid into the hole just until the cotton is absorbed. Replace the filler screw. Allow the flint wheel to dry before using your lighter.
Fill your Dunhill butane lighter with a gas refill. Turn the lighter over with the cap closed and remove the filler screw as in the above step. Position the pointer of the gas refill into the hole on the bottom of the lighter as far as it will go. You will hear a hiss as gas is being transferred to the lighter. Remove the gas refill from the lighter when drops of liquid gas appear at the base of the lighter.
Adjust the height of the flame in your Dunhill petrol lighter by grasping the wick with a pair of tweezers and lifting upwards slightly. Adjust the flame on gas models by turning the adjustment wheel on the rear edge of the lighter.
Change the flint on your Dunhill petrol lighter by turning the horizontal thumb screw on the flint tube at the top of the lighter in a counterclockwise direction. Remove the screw and spring and shake out the old flint. Place a new flint into the tube and replace the spring and thumbscrew.
Change the flint on your Dunhill butane lighter by using a fingernail to push back the metal slide at the top of the lighter. Shake out the worn flint and insert a new one. Push the metal slide back into position.
Dunhill recommends a 25mm flame height for normal use. Dunhill recommends using Dunhill lighter fluid only.
