13.2 Dirt Removal

The NEURO LOCK H O system knee joint is suited for a usage in wet areas. Nevertheless, dirt must be removed

when necessary and during regular maintenance. For this purpose, disassemble the system joint and clean the
soiled system components with a dry cloth.
In order to optimise the lifespan, we recommend rinsing the orthosis with water, especially after using it in
salt water, chlorine water and sand.
