• The
material of these components naturally changes over time, and repeated use causes deterioration,
wear, and fatigue. As a result, there is a hazard that these components may fail and cause serious personal
injury or death. It is difficult to judge the remaining life of these components from external inspection or the
feeling when operating, so always replace them at the specified interval.
• Replace or repair the defined life parts if any defect is found, even when they have not reached the speci-
fied replacement time.
