6.2.1
Refilling bearings with grease or replacing bearings
(1) If your fan is fitted with the pillow block, you can use the fan without lubrication. For longer
use, however, it is recommended to refill grease during periodic inspection.
(2) The following tables show the intervals and quantities of refilling grease. Be careful not to
overfill. Overfilling may cause an accident related to bearings. Use Shell Alvania Grease No.
3. Do not mix in or apply any other type of grease.
(3) Avoid using the fan in a dusty place. If such use is unavoidable, refill grease more often than
the specified intervals.
(4) While rotating the main shaft by hand, apply grease through the grease nipple using the
grease pump.
(5) The structure of some fans may not allow grease to be refilled. In such a case, after using
bearings for the duration of their service life, replace them with new ones.
