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 extended 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.

Monthly
●
Check the inlet screen, clean if necessary.
In case of an inlet filter (IF) being installed:
●
Check the inlet filter cartridge, replace if necessary.
Every 3 months

Check functions
Gas tight version only
Every 5000 hours or after 2 years
Depending on the requirements in terms of gas tightness:
●
Replace sealing rings (contact Busch).
Gas tight version only
Every 10000 hours or after 2
years
●
Check that pressure relief lines (PRL) are not clogged, see

Change the oil.
The change interval of 20000 operating hours is valid for
Busch approved oils only. The change interval depends very
much on the operating conditions. Borderline operation may
reduce the change interval down to approximately 5000
operating hours. Other oils may reduce the change interval.
Every 6 years
●
Have a major overhaul on the machine (contact Busch).
