Troubleshooting Guide
Periodic maintenance and component cleaning schedules should be set to assure reliability and performance of the fan.
Fan blades should be periodically wiped down to remove any build up of dust or dirt—depending on the environment.
Periodically check for excessive vibration while fan is running.
Periodically inspect and tighten all set screws and hardware—check torque on propeller.
Assure all mounting hardware remains properly secured.
Motors feature permanently sealed ball bearings and require no further lubrication.
