8.2.4 Stoppages
If the machine remains out of service for an extended period of time (> 1 month), it should be
commissioned regularly (around once a month) or, at the very least, the rotor should be
turned. Please refer to the instructions in the section titled "Switching on" before
recommissioning the machine. If a rotor locking device has been fitted to the machine, you
must remove it before the rotor starts to turn.
NOTICE
Restricted motor function
If not used for longer periods of time, material damage or complete motor failure can occur.
If the motor is out of service for a period of more than 12 months, then environmental
effects can damage the motor.
Apply suitable corrosion protection, preservation, packing and drying measures.
Taking the machine out of service
For details of measures that need to be implemented, see Preparing for use.
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.
