"保养明细表" can be translated into English as "Maintenance Details List" or "Maintenance Schedule/Breakdown".
"Maintenance Details List" directly conveys the idea of a detailed list related to maintenance.
"Maintenance Schedule/Breakdown" can also be appropriate, especially if it implies a structured or itemized breakdown of maintenance tasks, though "schedule" might lean more towards timing while "breakdown" emphasizes the detailed listing.
For most contexts where you're simply listing out the items or tasks involved in maintenance, "Maintenance Details List" is a clear and straightforward choice.
