| voltage too low, extension cord too long for available supply |
|
|
|
| voltage, or motor has been damaged.) |
| 6. | Thermal overload protection | 6. | Allow motor to cool for approximately 30 minutes, determine |

|
|
|
| low, extension cord too long for available supply voltage, or |
|
|
|
| motor has been damaged.) |
