Maintenance
Motor maintenance is generally limited to cleaning and lubrication (where applicable). Cleaning should be limited to exterior
surfaces only. Removing dust buildup on motor housing ensures proper motor cooling. Greasing of motors is only intended
when fittings are provided. Many fractional motors are permanently lubricated and should not be lubricated after installation.
Motors supplied with grease fittings should be greased in accordance with manufacturers’ recommendations. With motor
temperatures under 104°F (40°C), the grease should be replaced after 2000 hours of running time as a general rule.
Wheels require very little attention when moving clean air. Occasionally, oil and dust may accumulate causing imbalance.
When this occurs, the wheel and housing should be cleaned to ensure smooth and safe operation.
All fasteners should be checked for tightness each time maintenance checks are performed prior to restarting unit.
A proper maintenance program will help these units deliver years of dependable service.
Troubleshooting
NOTE: Before taking any corrective action, make certain unit is not capable of operation during repairs.
