DANGER!
DISCONNECT POWER PRIOR TO MAINTAINING OR CLEANING THE FAN!
The fan may start automatically causing serious injury or death.
Keep the fan clean for maximum life and best performance. Do not spray water on Fan
Shaft Bearings.
Periodically check the V-Belt. If necessary, adjust the spring tension to prevent the belt
from slipping.
The Motor and Fan Shaft Bearings are permanently lubricated. Grease Zerks are provided
on the Fan Shaft Bearings when relubrication is needed. Relubrication is required
whenever water comes in contact with the Fan Shaft Bearings. Slowly rotate the Fan
Shaft as bearing is filled with Grease. Use only high quality lithium soap base grease and
clean all dirt from Zerk before applying grease.
