8.1 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 appropri-
ate. Particularly harsh applications or heavy duty operation, such as high dust loads in the environ-
ment or in the process gas, other contamination or ingress of process material, can make it neces-
sary to shorten the maintenance intervals significantly.
Interval Maintenance work
Monthly In case of an inlet filter (IF) being installed:
● Check the inlet filter cartridge, replace if necessary.
Every 3 months ● Check the oil level, see Oil Level Inspection [➔17].
Every 6 months ● Clean the machine from dust and dirt.
In case of a coupling (CPL) being installed:
● Check the coupling (CPL) for backlash and wear.
Every 20000 hours ● Change the oil.
The change interval of 20000 operating hours is valid for Bus-
ch 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).
8.2 Oil Level Inspection
● Shut down the machine.
● When the machine is stopped, wait 1 minute before checking the oil level.
The oil level should stay constant over the lifetime of the oil. If the level does fall, this indicates a leak
and the machine requires repair.
● Fill up if necessary, see Oil Filling [➔11].
