8.8.2 Avoidance of damage to roller bearings during stoppages
Extended stoppages at the identical or almost identical resting position of the roller bearings
can lead to damage such as brinelling or formation of corrosion.
● During stoppages, regularly start the machine up for a brief period once a month, or at least
turn the rotor over several times.
If you have uncoupled the machine from the driven machine and secured the rotor with a
rotor shipping brace, then remove this before turning the rotor over or starting the machine
up.
Make sure that the resting position of the roller bearings after the rotor has been turned
over is different from what it previously had been. Use the fitted key or the coupling halves
as reference markers.
● During re-commissioning, refer to the information in the "Commissioning" section.

NOTICE
Damage as a result of an extended period out of service
If the machine is going to be out of service for longer than six months, then take the necessary
measures for preservation and storing. Otherwise damage to the machine will result.
Record the decommissioning steps. This log will be useful upon recommissioning.
8.10 Re-commissioning the machine
When you re-commission the machine, proceed as follows:
● Study the record made when the machine was decommissioned, and reverse the measures
that were taken for conservation and storage.
● Perform the measures listed in the "Commissioning" section.
