Fan Bearing Lubrication

• Grease zerks are provided for lubrication on the fan shaft bearings.
• Lubricate the fan every 2-6 months or whenever these components get wet.
• Disconnect power to the fan before lubricating.
• Clean the zerk before lubricating to prevent contamination from entering the bearing.
• Use a high quality lithium based, NLGI #2, grease such as Shell Gadus S2 V100 2. Do not use incompatible
greases containing aluminum, barium, calcium, bentonite clay or polyurea thickeners.
• Slowly rotate the fan shaft by hand while slowly applying the grease. Rapidly applying grease to a stationary
bearing can damage the bearing seals.
• Apply about .10 oz (2.8 g, 3.1 cc) of grease at a time or until a slight amount of grease can be seen purging
from the seal.

Service and maintenance of fans should be done only by a qualified technician.
Disconnect Power prior to maintaining or cleaning the fan! The fan may start
automatically causing injury or death.
1. Keep the fan clean for maximum life and performance.
2. Clean Shutter, Cone and Shroud for maximum life and performance.
3. The Fiberglass Fans are shipped with the Danger Decal fastened to the Fan
Shroud. Always keep the Decal clean and readable.
If the Decals becomes damaged or unreadable, order replacement Decals
immediately.
Clean the Shroud at the approximate location where the Decal will be placed.
Peel the backing off the Decal and affix it to the Shroud.
