contained in these statements.
A WARNING statement calls attention to an operating procedure, practice,
or condition, which, if not followed correctly, could result in injury or death
to personnel.
A CAUTION statement calls attention to an operating procedure, practice, or
condition, which, if not followed correctly, could result in damage to or
destruction of parts or the entire product.
