1 Preface
Regular maintenance is important – it increases the safety and service life of the product.
All rehab products should be checked and serviced once a year.
When using a product often, however, or when a product is being used by children or adolescents who are
still growing or by patients whose clinical picture changes, it is recommended to check, readjust and possi-
bly service the product at an interval of 6 months.
For all service and maintenance works use only original spare parts.
The service and maintenance works described in this manual should be performed by skilled specialist staff

This service and maintenance manual refers to the respective spare parts catalogues and instructions for
use manuals of the described products; therefore, please use all documents together.

ules and hand over a copy to the customer.

2 Safety
For all maintenance and repair works, there are a few points you should always observe:
Use appropriate tools (refer to pages 3 & 4).
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" – alternatively you can 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 Manual 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
fastenings please replace the respective nut or screw with a new thread lock and/or nut. If new
screws or nuts with thread lock are not available use a liquid thread lock substance with medium
strength (e.g. Loctite 241 or Euro Lock A24.20).

4.2 Front Wheel Attachment
Replacing the Front Wheels
Press on the wire bow in the wheels‘ hub and pull
the wheel off the axle. Repeat this process for the
opposite wheel. Pay attention to the spacers on the
axle, which provide for a distance between the wheel
and the housing.
For re-assembly, put the wheel onto the axle while
holding the wire bow depressed.
Attention: Slightly pull at the wheel to check if the
quick-lock has engaged and the wheel is securely
seated on the axle.
Replacing the Lower Swivelling Part of the
Front Wheel Attachment
After having removed the front wheels press together
the hooks under the lower swivelling part using pliers
and slide the lower swivelling part downwards off
the upper swivelling part.
For re-assembly, please proceed in reverse order.
Replacing the Swivel Lock
After having loosened the lower swivelling part you
can easily pull the swivel lock (arrowed) out of the
rail guide and replace it with a new swivel lock.
Attention:
Wheels with EVA foam tyres must be replaced, if
the material shows signs of cracking or damage
and when the tread becomes worn down to such
an extent that there is only 5 mm of radius left on
the outer edges of the tyre.

Drive the rivet into the anterior frame using a pin
punch (Ø 4 mm).
Repeat the process for the removal of the other riv-
ets, so the upper swivelling part can be removed.
When replacing the upper swivelling part do not for-
get to reinsert the solid core into to the upper swivel-
ling part before attaching it with rivets.
For re-assembly, plug all elements together and fas-
ten the upper swivelling part using two rivets.
Replacing the Upper Swivelling Part of the
Front Wheel Attachment
Carefully drill out the rivet head using a new drill bit
(Ø 6 mm).
If the nail in the rivet protrudes above the head of
the rivet, use a pin punch to drive the nail inwards so
you can use the rivet hole for guidance of the drill bit.

Replacing the left or right Push Handle

between the push handle and the folding scissor
construction as well as between the push handle
and the tilt mechanism of the backrest.
Next, loosen and remove the screw connections
between the push handle and the posterior frame as
well as between the push handle and the anterior
frame.
Remove the push handle.
For re-assembly, please proceed in reverse order.
Use new, self-locking nuts.
