Management of belts
For the belt, perform the tension management and visual inspection regularly according to the
description in section 4.3.1. If the blower has a belt driving system, powder dust is generated
from the belt. In particular, the amount of powder dust may be a little larger for approx. 2 months
after the start of operation. Unusually much powder dust may be generated due to abnormal
wear of the belt caused by inappropriate tension or inaccurate centering. In such a case, perform
an inspection.
5.5
Restart of operation after suspension or stoppage
In the case of suspension of the operation, take care about the storage environment even if the
period of storage is short. To prevent rust of the bearing, etc. during the suspension period,
rotate the impeller approx. 10 times manually or perform no-load running for approx. 5 minutes
once in a month. Before the restart of operation, make sure to perform an inspection similar to
that for test operation. In particular, check for materials adhering to the impeller or for corrosion
on it.

About the rotary sound of the bearing
The blower of the high-speed rotary or high temperature specifications of this blower chooses the
bearing of the C3 skimmer.
Therefore "a ball omission sound" may occur at the time of driving, but is not the abnormality of
the bearing.
When a rolling body enters the no load zone at the load zone, I come to be able to carry out a free
activity and begin to roll by gravity, and "a ball omission sound" is a sound when it collides in a
retainer and the orbit.
I show the example of the typical driving sound of the bearing.
Expression of the
sound
Characteristic
With ticktacks
Clangor
It attract attention in low speed.
It is consecutive sounds at a high-speed turn
Metallic sound
It change by a change of the rotary speed with a cylinder
Roller bearing and sound like a metallic sound mainly
when
it is big.
It stay temporarily when I supply grease.
