- DMonthly
Show answer & explanationAnswer & explanation
Correct answer: A. At the end of each work day
Air tanks should be drained at the end of each work day to remove moisture and contaminants. This prevents corrosion and freezing, which can damage the air brake system.
Why the other options are wrong
- B. Weekly draining is insufficient to prevent moisture build-up and potential issues.
- C. Annual draining is grossly inadequate and would result in severe system damage and failure.
- D. Monthly draining is far too infrequent and will lead to significant contamination and corrosion.
Air Tank Draining Frequency
The recommended interval for manually draining moisture and contaminants from air brake system reservoirs.
- Performed at the end of each work day.
- Removes water and oil that can freeze or corrode.
- Essential for air brake system longevity and safety.
Memory trick: Drain daily, keep the brakes sprightly!
