4.2 Maintenance Items
Maintenance is categorized into daily maintenance items (items to be carried at set intervals) and
periodic maintenance (replacement of parts when life is reached).
Some parts (HD, FDD, etc.) will not function in a hardware manner when the life is reached, so these
should be replaced before the life is reached.
