CORRECTION
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.
