Roller bearing
● If the motor has been stored for more than two years in a dry, dust-free and vibration-free
room, prepare for commissioning as follows:
– Replace the rolling-contact bearings on motors with lifetime lubrication.
– Replace the grease in motors with re-greasing system.
– If stored under less favorable conditions, the bearings or the grease must be replaced
after a storage period of approx. 18 months.
External fan
● All external fans fitted are ready for operation and have been connected so that they rotate
in the direction specified.
● The flow of cooling air is not impeded.
Cooling water supply
● The cooling water supply is connected and ready for operation.
● The cooling water supply is switched on. The data can be found on the rating plate.

7.4 Perform a test run with the water-cooled motor
If you want to start the machine for a trial run, ensure that it is connected to the cooling water
supply.
WARNING
Risk of burning from hot steam
If the cooling water supply fails, the motor will overheat. If cooling water runs into the hot
machine, hot steam suddenly forms, which escapes under high pressure. The cooling water
system can burst. This can result in death, serious injury or material damage.
Do not connect the cooling water supply until the machine has cooled down.
