A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Singer 191D-20 Industrial, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used.

What is an instruction?

The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of Singer 191D-20 Industrial one could find a process description. An instruction's purpose is to teach, to ease the start-up and an item's use or performance of certain activities.

Why don't we read the manuals?

An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of Singer 191D-20 Industrial, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Singer service. Lately animated manuals and instructional videos are quite popular among customers.
