Preventative maintenance
Please take a few moments each year to perform the following preventive maintenance inspection on your fan to ensure its safe and
efficient operation. Before contacting Customer Service, try resolving the issue using the troubleshooting procedures on the following
page. If you have any questions, contact Customer Service at 1-877-BIG-FANS.
Note: Actual installation setup may differ from picture.
Annual preventative maintenance
Perform the following maintenance procedures each year using the “Maintenance Checklist” in back of manual:
1. Check for the presence of the safety cable and shackle. The cable should be wrapped around the mounting structure, leaving as
little slack as possible. The shackle should be securely tightened and located on the topside of the mounting structure.
2. Ensure all 12 mounting bolts are present and torqued to 40 ft·lb (54.2 N·m). Ensure the lower cable is between the brackets of the
lower yoke.
3. Inspect motor terminals inside the junction box and tighten if necessary.
4. Check all connections in the fan controller and tighten as needed.
5. Check the gear reducer for oil leakage. If leakage is detected, contact Customer Service at 1-877-BIG-FANS.
6. Ensure airfoils are secured to one another by airfoil retainers.
7. Ensure all 20 bolts securing airfoils to fan are present and torqued to 29 ft·lb (39 N·m).
8. Inspect the lower safety cable to ensure it is secure.
9. Inspect the airfoils and main motor unit for signs of damage or cracks.
10.
Inspect the fan for signs of corrosion, discoloration, pitting, and flaking of metal.
General preventative maintenance
Periodically perform the following maintenance procedures on your fan:
•
Verify proper fan rotation. The fan should be turning counterclockwise when viewed
from the floor.
•
Dust the airfoils, motor, and motor housing. If desired, use a gentle cleaner or
degreasing agent to polish the foils. Do not use Clorox
®
or other chlorine based
cleaners, which could result in the release of toxic/fatal fumes!
•
Observe the motion of the fan during operation. The fan should not wobble or
precess. If any wobble is noticed, ensure the mounting structure is rigid enough to
support the fan and that the guy wires, if used, are sufficiently taut. If guy wires were
not used, Big Ass Fans suggests installing them. Contact Customer Service at
1-877-BIG-FANS.
WARNING: Do not operate a fan with missing or damaged
components. Please contact Customer Service at
1-877-BIG-FANS.
WARNING: Risk of fire, electric shock, or injury to persons during cleaning and user-maintenance! Disconnect the
appliance from the power supply before servicing.
WARNING: Before servicing or cleaning unit, switch off power at service panel and lock the service disconnecting means
to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely
fasten a prominent warning device, such as a tag, to the service panel.
WARNING: When service or replacement of a fan component in the fan requires the removal or disconnection of a safety
device, the safety device is to be reinstalled or remounted as previously installed.
