NOTICE
Improper storage or transport
Damage to bearings can result from improper storage or transport.
● On machines that have been supplied with a rotor shipping brace, secure the rotor as per
the notes on transportation (Page 31).
● Protect the motor against strong radial shocks and vibration when storing, as the rotor
shipping brace cannot completely absorb these forces.
● If the customer has already mounted parts, such as a coupling or belt pulley, the bearings
can be damaged during transport. In this case, make sure that the customer uses a rotor
locking device.
Long-term storage
If you are storing a machine for more than six months, you must check its condition every six
months. Store the machine in accordance with the specifications in Section "Storage
(Page 33)", and if possible, packed.
● Check the motor for damage.
● Carry out any necessary maintenance work.
● Make sure that the storage conditions are such that condensation cannot form in the motor.
● If the machine is not sealed in plastic film, continually and slightly heat the machine, e.g.
with anti-condensation heating (if available), and ensure that the air circulates in the storage
room.
Storage for longer than three months
Lubricate the machine after every two years of storage.
1. Unpack the machine.
2. Remove the rotor shipping brace, if one is being used.
3. When stored for longer than two years, lubricate with twice the grease quantity in
accordance with the lubricant plate. This ensures that the grease is evenly distributed and
covers all surfaces. Corrosion damage is avoided.
NOTICE
Damage to roller bearings
Roller bearings can be damaged when kept in the same or almost the same position.
Every three months, manually rotate the rotor through five revolutions. Make sure that the
resting position of the roller bearings after the rotor has been turned is different from what
it previously had been. Use the feather key as a reference point, if present.
4. Replace the corrosion protection.
