12.3. Maintenance
Maintenance intervals
After 3 years at the latest for Ex certified products.
Lubrication
●
In the factory, the gear housing is filled with grease.
●
Grease change is performed during maintenance
- Generally after 4 to 6 years for modulating duty.
- Generally after 6 to 8 years if operated frequently (open-close duty).
- Generally after 10 to 12 years if operated rarely (open-close duty).
●
We recommend exchanging the seals when changing the grease.
●
No additional lubrication of the gear housing is required during operation.
Notes regarding the
maintenance
●
Perform visual inspection of actuator. Ensure that no outside damage or changes
are visible.
●
Electrical connection cables must be placed properly and in perfect condition.
●
Thoroughly touch up any possible damage to painting to prevent corrosion.
Original paint in small quantities can be supplied by AUMA.
