1 Preface
Regular maintenance is important – it increases safety and service life of the product.
All rehab products should be checked and serviced once a year.
It is however recommended that rehab products be checked, readjusted and possibly serviced every 6
months if they
are used frequently or if the user is growing or the user‘s clinical picture changes.
For all service and maintenance work, use only original spare parts.
The service and maintenance work described in this manual should be performed by skilled specialist staff
only and not by the user of the product.
This service and maintenance manual refers to the respective spare parts catalogs and instructions for use
of the described products; therefore, please use all documents together.
Please use the maintenance schedules (check list) for duplication. Keep the completed maintenance schedu-
les and hand over a copy to the customer.

2 Safety
For all maintenance and repair work, there are a few points you should always observe:
Use suitable tools. (refer to page 3 and the following pages)
Wear appropriate clothing as well as gloves and safety glasses, if necessary.
Secure the product to prevent it from tipping over or falling off the workbench, for example.
Study the service and maintenance instructions before beginning your work.
You should become familiar with the functions of the product first. If you do not know the product,
please first study the instructions for use before inspecting the product.
If no instructions for use are available to you, please order them from the manufacturer (refer to
the overview of all Otto Bock Branches „Otto Bock Worldwide“).
You can also download the document from our homepage under www.ottobock.de or
www.ottobock.com.
Clean / Disinfect the product before starting inspection. Please also refer to the instructions for
use regarding any care instructions or specific product inspection information.
Many of the screw fastenings use thread lock or nylock nuts. If you have to undo such screw
connections, please replace the respective nut or screw with a new thread and/or nylock nut. If
new thread lock or nylock nuts are not available, use a liquid thread lock substance with medium
strength (e.g. Loctite 241 or Euro Lock A24.20).
