2.3 Maintenance intervals
The motor must be checked for unusual running noises and/or vibrations once a week or every

Please check the roller bearings at a minimum interval of 10,000 h and replace them if necessary. The
interval may be shorter depending on the operating conditions. Also check the electrical connections,
cables, strands and fans for strength and damages. Check the function of the insulation system.
Replace the radial shaft seals every 10,000 h.
There must be no dust deposits on the motor’s surface that may impair cooling.
The motor must be completely overhauled at intervals of five years.
