Maintenance and Care 

 

Notes 

Original spare parts 

When replacing damaged parts (wearing parts/spare parts) only 
use SCHUNK original spares. 

Maintenance of module with gripping force maintenance "A.D. 
gripping" (A.D.)

  

The pistons have to be aligned using an assembly device. There-
fore we recommend to have the module serviced and the seals re-
placed by SCHUNK. 
If this is not possible, you can carry out the maintenance and re-
place the seals yourself. 

 

Maintenance and lubrication intervals 

  

 

NOTICE 

At ambient temperature above 60°C the lubricants can  
harden faster. 

•  Interval decrease accordingly.
