A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of MTD 520/550/551/554, 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. A necessary precondition for this is the unmistakable, legible character of an instruction.

What is an instruction?

The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of MTD 520/550/551/554 one could find a process description.

Unfortunately, only a few customers devote their time to read an instruction of MTD 520/550/551/554. A good user manual introduces us to a number of additional functionalities of the purchased item, and also helps us to avoid the formation of most of the defects.
