3 Intended use
The safe use of the product can only be ensured in case of intended use in accordance with the information con
tained in these instructions for use. The user is ultimately responsible for accident-free operation.
3.1 Indications for use
The wheelchair is intended for everyday indoor and outdoor use, by the user or an attendant, of people with tem
porary or permanent limitations of the ability to walk, inability to walk or difficulty standing up.
The product is suitable for users with intact skin whose anatomy (suchas body dimensions and weight) permits the
intended use of the product.
The wheelchair may only be used with the options listed on the product order form.
Ottobock assumes no liability for combinations with medical devices and/or accessories from other manufacturers
outside the modular system.
Combinations based on a combination agreement that have been evaluated for effectiveness and safety are an
exception to this.
3.1.1 Special features of the CLT version
In the CLT version, the wheelchair features permanently welded side supports for mounting the drive wheel attach
ment devices, a permanently welded back support and permanently welded caster attachment devices. In this
weight-saving version, the back support height and back support angle, for example, cannot be subsequently
adjusted. Furthermore, installation of certain options is not possible with this version.
For these reasons, this wheelchair version is intended only for experienced users with sporting ambitions who,
thanks to their physiological capabilities, are able to handle the wheelchair proficiently. Before fitting with this ver
sion, the user should be examined intensively for suitability (adequate physiological capabilities).

The side panels protect the user and his/her clothing from getting dirty.
If armrests have been installed on the wheelchair, they offer the user additional support for the forearms.
