| NOTE | |
| Current style electric motors run relatively hot under normal operating | ||
| conditions, with reasonable air compressor loading. This condition is | ||
| normal and no adjustment is necessary. | ||
| Under normal operating conditions, the motor amperage draw will | ||
| not exceed the nameplate amperage rating, plus the service factor, as | ||
| it appears on the electric motor. If a condition of sustained high | ||
| amperage exists, refer to service checks above and/or consult | ||
| electrician. If cause cannot be isolated by an electrician, consult with | ||
| Service Center for additional assistance. | ||
