The plus and minus lever on the front is to control how big the opening will be when the valve opens. Bigger hole = more fuel released = bigger flame.
How do you set up a lighter?
Hold the lighter in your dominant hand. The ignition button, when pressed, releases the gas valve to the fuel tank. In order to light the lighter, you'll need to strike the sparkwheel and hold the ignition button at the exact same time. Don't worry--the process is much simpler than it may sound.

Do lighters run out?
Assuming the lighter doesn't rust, it can be stored for years and still work. The only major reason for it to not work is if it runs out of fuel or if the butane fuel is able to escape from the lighter. The escape rate is determined by the aperture of the vent, the temperature of the air, and usage patterns.
What is a lighter used for?
Lighters are used for a variety of tasks including lighting candles, igniting grills and camp fires and lighting cigars. Manufactured by a variety of companies in different shapes, sizes and colors, lighters commonly use butane as fuel. Adjusting the flame of a lighter can be done so the flame height can be matched to the task at hand. Flame adjustment is done by means of a control typically located on the bottom of the lighter.

Turn the control to the left, or counter clockwise, toward the plus sign to increase the height of the lighter flame. Slowly turn the control and do not force it to prevent potential damage to the lighter.

Position the flame height control in the middle -- half way between the plus and minus signs -- as a starting point for adjustment with a new lighter. A middle setting will result in a medium-size flame that allows for adjustment up or down.
What is minus sign?
The minus sign, −, has three main uses in mathematics: 1 The subtraction operator: a binary operator to indicate the operation of subtraction, as in 5 − 3 = 2. Subtraction is the inverse of addition. 2 The function whose value for any real or complex argument is the additive inverse of that argument. For example, if x = 3, then −x = −3, but if x = −3, then −x = +3. Similarly, − (−x) = x. 3 A prefix of a numeric constant. When it is placed immediately before an unsigned numeral, the combination names a negative number, the additive inverse of the positive number that the numeral would otherwise name. In this usage, ' −5 ' names a number the same way 'semicircle' names a geometric figure, with the caveat that 'semi' does not have a separate use as a function name.
What is the plus and minus sign in elementary school?
Use in elementary education. Some elementary teachers use raised plus and minus signs before numbers to show they are positive or negative numbers. For example, subtracting −5 from 3 might be read as "positive three take away negative 5", and be shown as. +3 − −5 becomes +3 + +5 = +8.
What is the hyphen minus sign?
The hyphen-minus sign, -, is the original ASCII version of the minus sign, which doubles as a hyphen. It is usually shorter in length than the plus sign and often at a different height to the plus-sign's cross bar. It can be used as a substitute for the true minus sign when the character set is limited to ASCII.
What is plus and minus in computer?
As well as the normal mathematical usage, plus and minus signs may be used for a number of other purposes in computing. Plus and minus signs are often used in tree view on a computer screen—to show if a folder is collapsed or not.
What does the minus sign mean in the alphabet?
In the International Phonetic Alphabet, subscripted plus and minus signs are used as diacritics to indicate advanced or retracted articulations of speech sounds.

Blood types are often qualified with a plus or minus to indicate the presence or absence of the Rh factor. For example, A+ means type A blood with the Rh factor present, while B− means type B blood with the Rh factor absent.
What does the + sign mean in Latin?
The + sign is a simplification of the Latin: et (comparable to the evolution of the ampersand & ). The − may be derived from a tilde written over ⟨m⟩ when used to indicate subtraction; or it may come from a shorthand version of the letter ⟨m⟩ itself.
How to tell if a candle lighter is refillable?
Check the bottom of your candle lighter to determine if it's refillable. If so, it has a valve at the bottom of the device, opposite the lighter tip end. Use only butane in a refillable candle lighter. If you're unsure what to buy, ask a representative at a store that sells an assortment of butane cigarette lighters.
How far away from the wick should the lighter be?
Hold the lighter so the tip of the nozzle is approximately an inch away from the candle wick.
How long does it take for a butane lighter to rest?
Step 3. Remove the butane container from the lighter when the butane sprays out a little. Allow the lighter to rest for at least two minutes, to let the parts inside it readjust so the lighter functions properly once again. Kathy Adams is an award-winning writer.

Overview
The plus and minus signs, + and −, are mathematical symbols used to represent the notions of positive and negative, respectively. In addition, + represents the operation of addition, which results in a sum, while − represents subtraction, resulting in a difference. Their use has been extended to many other meanings, more or less analogous. Plus and minus are Latin terms meaning "more" and "less", respectively.
History
Though the signs now seem as familiar as the alphabet or the Hindu-Arabic numerals, they are not of great antiquity. The Egyptian hieroglyphic sign for addition, for example, resembled a pair of legs walking in the direction in which the text was written (Egyptian could be written either from right to left or left to right), with the reverse sign indicating subtraction:
Nicole Oresme's manuscripts from the 14th century show what may be one of the earliest uses …
Plus sign
The plus sign, +, is a binary operator that indicates addition, as in 2 + 3 = 5. It can also serve as a unary operator that leaves its operand unchanged (+x means the same as x). This notation may be used when it is desired to emphasize the positiveness of a number, especially in contrast with the negative numbers (+5 versus −5).
The plus sign can also indicate many other operations, depending on the mathematical system …
Minus sign
The minus sign, −, has three main uses in mathematics:
1. The subtraction operator: a binary operator to indicate the operation of subtraction, as in 5 − 3 = 2. Subtraction is the inverse of addition.
2. The function whose value for any real or complex argument is the additive inverse of that argument. For example, if x = 3, then −x = −3, but if x = −3, then −x = +3. Similarly, −(−x) = x.
Use in elementary education
Some elementary teachers use raised plus and minus signs before numbers to show they are positive or negative numbers. For example, subtracting −5 from 3 might be read as "positive three take away negative 5", and be shown as
3 − 5 becomes 3 + 5 = 8,
or even as
Use as a qualifier
In grading systems (such as examination marks), the plus sign indicates a grade one level higher and the minus sign a grade lower. For example, B− ("B minus") is one grade lower than B. In some occasions, this is extended to two plus or minus signs (e.g., A++ being two grades higher than A).
Positive and negative are sometimes abbreviated as +ve and −ve.
In mathematics the one-sided limit x → a means x approaches a from the right (i.e., right-sided li…

Other uses
In physics, the use of plus and minus signs for different electrical charges was introduced by Georg Christoph Lichtenberg.
In chemistry, superscripted plus and minus signs are used to indicate an ion with a positive or negative charge of 1 (e.g., NH+ 4 ). If the charge is greater than 1, a number indicating the charge is written before the sign (as in SO2− 4 ). The minus sign is also used, in place of an en dash, for a single …
