4.2 Maintenance Instructions
Note:
As a basic principle, all Ottobock modular adapters are subjected to tests
involving three million load cycles. Depending on the amputee's activity
this corresponds to a service life of three to five years.
We recommend carrying out regular safety checks once a year.
