Precautions for components having dened life spans
• “Components having dened life spans” are those expected to wear out or break down
within a 10-year period of use or in storage under normal conditions. Components designed
for a life span of at least 10 years are excluded from the category.
• The “recommended replacement cycle” is the interval between preventive maintenance for
components having dened life spans. It does not guarantee breakdown-free operation dur-
ing that period.
• The recommended replacement cycle is a guideline. The actual replacement cycle may
vary depending on the environmental conditions of use, such as ambient temperature.
• The recommended replacement cycle is subject to change according to performance in the
eld.
