What classification of an oil leak deadlines the loader?

• A. Class 1
• B. Class 2
• C. Class 4
• D. Class 3

Answer: (D)

Oil leaks are categorized to show how serious the leak is and what action is required. The important idea is that as leaks become larger, the risks to the machine, safety, and the environment rise, so the response moves from monitoring to stopping and repairing. The category described as the one with a clear, noticeable leak—visible drips or pooling—indicates a level of severity that means the loader should be shut down and repaired before continuing. Lower categories are minor seepage that can be monitored or fixed during routine maintenance, while higher categories imply even more urgent action. So the classification that signals the loader must stop and be serviced is the one that corresponds to Class 3.
