Problem | Probable Cause | Correction |
Unit will not run | Tank pressure exceeds “cut in” pressure | Once pressure drops below “cut in” pressure, the unit will start. |

|
| (use of extension cords is not recommended). |
| Fuse or circuit tripped | Replace fuse or reset breaker |

| ||||
| (typically temperatures below freezing) | then try restarting. | ||
Air leaks at fittings | Fittings loose | Tighten fitting. Check with soapy water. DO NOT OVER TIGHTEN. | ||
Unit will not build pressure | Application requires excessive air demand | Reduce demand on compressor | ||
| Loose head | Tighten bolts on head | ||
