🔍 Key Concepts

• Study which labeled component is directly associated with the lubricating oil reservoir for this system, not air or electrical controls. • Compare which parts look like drains or outlets (at the bottom of tanks) versus which part looks like a fill or service point for adding oil. • Notice the small assembly enlarged at the right side of the illustration and how it connects back into the main system — this often shows the oiler or lubricator used for the compressor or blower.

💭 Think About

• Which labeled component is located at or above a container that clearly holds fluid and would reasonably be used to pour oil into, rather than remove it? • Among choices D, F, M, and R, which letters in the figure are attached to devices that look like controls, drains, or sensors (things you would not pour oil into)? • Look closely at the zoomed‑in detail view on the right: does any part there look like a cup or reservoir with a removable cap where oil could be added?

✅ Before You Answer

• Confirm that the component you choose is directly connected to the lubrication pathway toward the moving machinery, not just to an air or electrical line. • Make sure the component is not clearly marked as a drain, gauge, or switch in the illustration. • Verify that the component you select is physically shaped so that oil could be poured into it from above (such as a capped cup or filler plug).
