Taking the machine out of service
Detailed information on how to take the machine out of service is provided in Chapter Preparing
for use (Page 27).
Lubricating before recommissioning
NOTICE
Dry running bearings
Bearings can be damaged if they do not have sufficient grease.
● Re-grease the bearings if they have been out of service for more than one year. The shaft
must rotate so that the grease can be distributed in the bearings. Observe the data on the
lubricant plate.
● More information can be found in Chapter Regreasing rolling bearings (Page 98).
8.8.2 Rolling bearing damage when at a standstill
Extended stoppages at the identical or almost identical resting position of the rotor in the rolling
bearings can result in damage, such as brinelling or corrosion.
● During stoppages, regularly start up the machine for a brief period once a month. As a
minimum, turn the rotor 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 up the
machine.
Make sure that the resting position of the rotor after the rotor has been turned over is
different from its previous position. Use the fitted key or the coupling halves as reference
markers.
● During recommissioning, refer to the information in Chapter "Commissioning".
