When troubleshooting a pneumatic system, what is a common first step?

Checking for leaks is a common first step when troubleshooting a pneumatic system because leaks can significantly affect the system's performance and efficiency. Pneumatic systems rely on the pressure of air to operate, and any leaks in the hoses, fittings, or components can lead to a drop in pressure, causing the system to malfunction or not operate at all. By identifying and addressing leaks early in the troubleshooting process, you can often resolve the issue without having to inspect other components or perform more complex interventions. This approach saves time and helps to avoid unnecessary repairs or replacements, ensuring a more systematic and efficient troubleshooting process.
