TROUBLE SHOOTING GUIDE
NOTE: REMOVE POWER SOURCE AND DRAIN TANK PRESSURE PRIOR TO MAKING ANY REPAIRS OR ADJUSTMENTS.
Problem | Cause | Correction | |||
Unit will not run | Tank pressure exceeds “cut in” pressure | Once pressure drops below “cut in” pressure, the unit will start. | |||
| Extension cord causing excessive amp draw | Check guidelines for proper cord gauge | |||
|
| (use of extension cords is not recommended). | |||
| Fuse or circuit tripped | Replace fuse or breaker | |||
| Unit not turned on or not plugged in | Check pressure switch and verify that it is in the Auto position. | |||
|
| Verify that unit is plugged in. | |||
| Air filter plug not removed | Remove air plug and install Air filter. | |||
| Cold weather conditions | Place compressor in warmer environment for at least 30 minutes | |||
| (typically temperatures below freezing) | then try restarting. | |||
Air leaks at fittings | Fittings loose | Tighten fitting. Check with soapy water. DO NOT OVER TIGHTEN. | |||
Air leak at pressure switch | Clogged check valve | Remove and clean check valve | |||
Unit will not build pressure | Application requires excessive air demand | Reduce demand on compressor | |||
| Loose head | Tighten bolts on head | |||
| Blown gasket | Remove head and check for broken or deformed gasket. Replace | |||
|
| if needed. | |||
Unit will not build pressure | Worn or broken valves | Remove head and replace valves. | |||
