chapter "Transport (Page 28)".
9.2.1
Prepare servicing work
● The drawings and parts lists do not contain any detailed information about the type and
dimensions of fixing elements and components. For this reason, you should establish this
information when dismantling them and make a note of it for the purpose of reassembly.
● Document the type, dimensions and arrangement of the parts so that you will be able to
reassemble the machine to its original state.
● Use suitable tools to disassemble the machine.
● Take measures to prevent parts from dropping down before you dismantle them, e.g. by
replacing fastening elements with extra-long screws, threaded bolts or similar. This ensures
that the part is supported after it is pulled off.
● The centerings in the shaft extensions have reset threads. Use lifting gear which is suitable
for the rotor weight and direction of loading.

however, after 10 years at the latest.
