It is necessary to periodically check the correct tension of the drive belt and, if necessary, adjust it. It is also necessary to check the belt for cracks, wear, fraying or other signs of aging, and, if necessary, replace it. In addition, check the location of the belt: it should not come into contact with engine parts. After replacing the drive belt after two or three weeks, the new belt should be re-adjusted to eliminate slack after it has stretched.
