9.1.6 Servicing and maintaining the anti-condensation heating
The anti-condensation heating is maintenance-free. If it is defective, contact the Service Center
(Page 167).
9.1.7 Assessing the roller bearings
To assess the roller bearings, it is generally not necessary to dismantle the machines. The
motor only has to be dismantled if the bearings are to be replaced.
The state of a roller bearing can be assessed by analyzing the bearing vibration. The measured
values provide an indication and can be assessed by specialists. Contact the Service Center.
WARNING
Explosion hazard due to overheating of the rolling bearings
If the rolling bearings are not regularly regreased, local overheating may be possible, and, as
a consequence, an explosion in an explosive atmosphere. This can result in death, serious
injury, or material damage.
● Regrease the rolling bearings regularly according to the lubrication plate.
● Implement bearing temperature monitoring if not yet in existence.
