Which of the following scenarios suggests the need for immediate maintenance in a pneumatic system?

The scenario that indicates an immediate need for maintenance in a pneumatic system is low-pressure readings. Pneumatic systems rely on a specific pressure range to operate effectively and ensure safety. Low-pressure readings can lead to inadequate force, causing malfunctioning actuators, slower response times, and ultimately impacting process efficiency. Such pressure issues may also signify potential leaks, blockages, or failing components within the system that require prompt attention to prevent further breakdowns or safety hazards.

In contrast, normal operation of actuators, regular checks, and consistent air output indicate that the system is functioning as intended and does not necessitate immediate intervention. Therefore, recognizing low-pressure readings as a critical warning sign helps maintain the health and reliability of the pneumatic system.
