INFORMATION

tion and use. To do so, you can request this service manual and other documentation from the manufacturer (see
the overview of national Ottobock branches on the inside of the back cover).
INFORMATION
Clean and disinfect the product before commencing service work.

INFORMATION
Screws and nuts with thread lock are used for many screw connections. If you loosen screw connections, be
sure to replace the respective nut or screw with one equipped with a new thread lock. If new screws or nuts with
a thread lock are not available, use a medium-strength liquid thread locking compound (such as Loctite 241 or
Euro Lock A24.20).

Due to changes in the configuration, new components may be missing in the available instructions for use (user or
