6.3 Refill and change of grease (oil)
Warning
The main shaft, V-belt pulley, and V-belt are rotating during
operation. Care must be taken so that your clothing is not caught in
these parts.
6.3.1. Rolling bearing
(1) An insufficient amount of grease may cause
poor lubrication. On the contrary, excessive
grease may cause the grease to be stirred
and generate heat. After a long time of use,
grease deteriorates partially, resulting in
lower lubrication properties. Refill the proper
amount of grease at the proper intervals.
(2) The following tables show the intervals and
quantities of grease to be refilled. Be careful
not to overfill. Use Cosmo Dynamax Super
No. 2 or the equivalent of another brand. Do
not mix or apply any other type of grease.
(3) While the fan is running, apply grease
through the grease nipple using the grease
pump.
Old grease collects in the bearing housing. Drain it through the drain port at the bottom.
