7.1 Maintenance Schedule
The maintenance intervals depend very much on the individual operating conditions. The
intervals given below are considered as starting values which should be shortened or ex-
tended as appropriate. Particularly harsh applications or heavy duty operation, such as
high dust loads in the environment or in the process gas, other contamination or ingress of
process material, can make it necessary to shorten the maintenance intervals significantly.
