Question: During a pre-shift inspection of a bulldozer, you observe that the hydraulic oil reservoir sight glass is extremely low, barely visible. What should you do next?

Answer options:

• Top up the reservoir with any available general-purpose oil to save time. ✅ Immediately notify your supervisor and do not operate the machine until the correct type and quantity of hydraulic fluid has been added and the system inspected for leaks.
• Proceed with light-duty work as the machine has some residual hydraulic pressure.
• Check the machine's maintenance log to see when the hydraulic fluid was last changed.

Correct answer: Immediately notify your supervisor and do not operate the machine until the correct type and quantity of hydraulic fluid has been added and the system inspected for leaks.

Explanation: Operating a machine with severely low hydraulic fluid can cause pump cavitation, overheating, and damage to the hydraulic system components. The machine should not be operated until the issue is rectified with the correct fluid and potential leaks are investigated.
