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.
Every 3 months
• Check the oil level, see
Every 6 months
• Clean the machine from dust and dirt.
Every 20000 hours
• Change the oil.
The change interval of 20000 operating hours is valid
for Busch approved oils only. The change interval de-
pends very much on the operating conditions. Border-
line 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).
7.2 Oil Level Inspection
• Shut down the machine.
• When the machine is stopped, wait 1 minute before checking the oil level.
