The term manual comes from the Latin word manuālis. He concept It has several uses according to the context, either as an adjective or as a noun.

What is done or handled with the hands receive the qualification of manual . By example : "The machine is malfunctioning, we must turn the grinder manually", “I love this dress: it was handmade, with great manual work”, “My computer broke down so I had to write down all the addresses manually”.

Broadly speaking, we can say that in the past all jobs and tasks were carried out manually, while today the opposite is true: the machines save us time and physical energy in almost all of our activities , both industrially and domestically.

We can think of food, clothing manufacturing, scientific research, drawing or writing itself: today we usually use devices to make our products and store our creations of all kinds. The methods manuals have not disappeared, but have become very rare: there are still people who make all kinds of meals manually, as are those who make clothes, paint or write without relying on automation.

In the vehicles , the manual transmission It is the system through which the driver must modify the gear ratio by manipulating a gearbox with his right or left hand, depending on the region. To make the changes, the subject must step on the clutch pedal to decouple the transmission and engine and then move a lever that is on the floor.

While this may be rare or too complicated for many people today, until a few decades ago it was the only option that existed. The transmission Automatic is the most common today, and consists precisely of a system that gives the driver the comfort of not having to make changes, since this process is done by the car itself using different parameters and technologies.

It is called manual tool on the other hand utensil It is used to perform various tasks with your hands. These tools, such as a hammer, a clamp or a screwdriver, minimize energy use and effort.

In this case we find a concept that can be slightly ambiguous, since being a tool, that is, a creation of the human being, its use implies a series of mechanisms that were not in our nature but we had to to learn. Despite this, since they do not depend on the automation that can provide us with an electronic device, they are part of the manual tasks.

Manual is also a noun that is used to refer to a book or notebook It gathers important information about an issue. Many times the manuals present the instructions for operating an appliance or other type of machine.

A manual or user manual , in this way, explains how to use a device. These publications usually include details of the available options and teach the operation of the keys or buttons, to mention some possibilities.

The instruction manual usually presents different sections in several languages. The first one is for the list of the parts that make up the product: for example, in the case of a device Electronic cables and accessories are included. Then there are explanations for the first use, maintenance and troubleshooting. Depending on the complexity of the product, the extension of the manual can vary considerably.
