Which item is a monthly maintenance task?

• A. Filter inspection/replacement
• B. Pressure testing
• C. Complete system audit
• D. System flushing

Answer: (A)

Keeping hydraulic fluid clean and protecting components starts with the filter. Filters are the first defense against dirt and particulates in the system, and they wear out or clog over time. Regular inspection and replacement, typically on a monthly cycle, help maintain proper flow, keep differential pressure in check, and prevent contamination from reaching pumps, valves, and actuators. Other tasks are more invasive or comprehensive and are performed less often: pressure testing is used to verify integrity during setup or after a problem, a complete system audit is a thorough review done periodically (not monthly), and flushing is a cleaning action reserved for specific contamination issues or major service.
