Preventive maintenance
The purpose of preventive maintenance is to keep unforeseen failures to a minimum. This
satisfies the prerequisites for system compliance with the guaranteed, long-term charac-
teristics.
The effects of different operating conditions (full or partial load operation, temperature,
size of dust particles, humidity, gases, vapors) are checked and the condition of parts sub-
ject to wear is determined by recording and analyzing characteristic values. Preventive
measures must be adopted or repairs must be undertaken as appropriate.
The specified maintenance intervals correspond to the minimum requirements. Compli-
ance with stricter national legislation may occasionally be necessary.
