This short video shows how to adjust a pressure switch. Pressure Switch Adjustment Procedure Adjusting pressure switches can be difficult and time consuming unless a uniform and correct approach is used.  The following instructions are based on adjusting the most common pressure switches.  On 69H style switches the large metallic screw (A) is used first to adjust the cut-in pressure (the point at which the compressor comes on as system pressure decreases).  The sm …

This short video shows how to adjust a pilot unloader valve. IMPORTANT:Be sure to check the low and high RPM’S on the engine (e.g. the high RPM at 3,400 and the low RPM at 2,200). If the low RPM setting is too low, it can cause the engine to shut down, at the low idle speed. Oftentimes, when a pilot valve "chatters", it's due to the differential being set too close together. What this means is instead of, say, an idle PSI of 95 and a cut-off PSI of 125, it could be closer to 110/125 or 115/125. …
