Maintenance
IMPORTANT! Disconnect Power Prior To Maintaining Or Cleaning The Fan. The fan may start
automatically causing serious injury or death.
• Service and repair of fans should be done only by a qualified technician.
•Minimize contact of moisture or corrosive chemicals to the surfaces of the fan components to maximize
fan life.
•After washing fans, operate fans long enough to remove moisture from all fan surfaces.
• Keep the fan clean for maximum life and best performance. Do Not spray water on the Fan Shaft
Bearings, the Belt Tensioner, or the Motor.
• Periodically check the V-Belt and replace if necessary. A worn Belt will cause a substantial drop in Fan
performance or it can break and cause Fan failure. If a Belt rides below the Sheave edge, replace the
belt. (See below)

• The motor and Fan Shaft Bearings are pre-lubricated. Grease zerks are provided on the fan shaft bear-
ings for installations where re-lubrication is needed. Add only a small amount of grease to purge impu-
rities out of the bearing seals. Use only high quality lithium soap base grease and clean all dirt from
zerk before applying grease. Chore-Time recommends using Shell Alvania # 2 in the fan shaft bear-
ings.
•Check Sheaves for wear. Replace if a Sheave groove is worn.
