Periodical check and maintenance are essential for the safe riding.
An ATV has a lot of components assembled, and as time goes by, degradation and abrasion of such components develops. Daily and periodically check such conditions and anticipate future such condition changes, which is the basis of required maintenance.
Therefore, such checks prevent serious trouble and excessive expense, and provide security up to the next check.
Oil and liquids are used in many sections in an ATV.
Oil and liquids used in the engine, transmission and radiator play the roles of lubrication of the system, cooling and rust prevention to maintain the basic functions of an ATV.
Human blood is cleaned in our lung and kidney and circulated in our body. However as the oil circulated in an ATV cannot be cleaned, replenishment and change are required in periodical checks or at times specified by the manufacturer.
