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 fitted.
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
Rolling bearing damage due to unchanged resting position
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 rotor after the rotor has been turned over is
different from its previous position. Use the feather key as a reference point, if present.
4. Replace the corrosion protection.
5. Reattach the rotor shipping brace, if present.
6. Pack the machine again.
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 38)", 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.
