| Overheating. | 1. | Poor ventilation. | 1. | Relocate air compressor to an area | 
| 
 | 
 | 
 | 
 | with cool, dry, well circulated air. | 
| 
 | 2. | Dirty cooling surfaces. | 2. | Clean all cooling surfaces of pump | 
| 
 | 
 | 
 | 
 | and motor thoroughly. | 
| 
 | 3. | Leaking valve. | 3. | Have a qualified service technician | 
| 
 | 
 | 
 | 
 | replace worn parts and | 
| 
 | 
 | 
 | 
 | |
| Motor stalls. | 1. | Low voltage. | 1. | Do not use an extension cord. | 
| 
 | 
 | 
 | 
 | Link additional air hoses together | 
| 
 | 
 | 
 | 
 | to acquire additional length. | 
| 
 | 2. | Defective pressure switch | 2. | Have a qualified service technician | 
| 
 | 
 | bleeder valve. | 
 | replace defective pressure switch | 
| 
 | 
 | 
 | 
 | bleeder valve. |

 | 
 | 
 | 
 | 
 | 
| Pressure relief valve opens. | 1. | Air tank pressure has exceeded | 1. | Have a qualified service technician | 
| 
 | 
 | normal operating pressure. | 
 | replace pressure switch. | 
| 
 | 2. | Pressure switch is stuck. | 2. | Have a qualified service technician | 
| 
 | 
 | 
 | 
 | replace pressure switch. | 
| Motor will not run. | 1. | Air tank pressure exceeds preset | 1. | Motor will automatically start when | 
| 
 | 
 | pressure switch limit. | 
 | air tank pressure drops below 85 | 
| 
 | 
 |

 | 
 | 
 | 15 AMP Buss fuse is acceptable. |
