6 Use
6.1 Techniques for using a wheelchair
Information and practical tips on fundamental techniques for using the wheelchair can be found in the brochure
"Techniques for using a wheelchair" supplied with the product.
Should the brochure not be included with the product, it can be ordered under reference number 646D60. Further
information on obtaining the brochure can be provided by the qualified personnel supplying the wheelchair or by
Ottobock Service (addresses: see back inside cover or back cover).
6.2 Further instructions for use
Attaching loads (e.g.backpacks) can adversely affect stability. Therefore, when surmounting obstacles or driving
on ramps or inclines, always remove the additional load or activate the anti-tipper.
The load must not exceed 5kg.
We recommend that you always attach a wheelchair backpack to the push handles with the attachment straps
provided.
• The recommended overall width for manual wheelchairs in an operational state is 700mm. This specification
should ensure unhindered use of escape routes,for example. Please note that the product dimensions can
exceed the recommended value in versions with very large seat widths (for more information see see Page33
ff.).
• The wheelchairs in this series fully satisfy the minimum technical requirements for wheelchairs transportable by
train. However, please note that it is possible that not every individual wheelchair will fulfil the minimum require
ments due to the variation in designs (please see see Page34 for further details).
6.3 Getting in and transferring
CAUTION
Incorrect handling when getting in
Risk of falling, tipping or rolling away due to incorrect handling
►Activate the wheel lock each time before you get into or out of or transfer to or from the wheelchair.
►Always get into the wheelchair from the side, where possible.
►Never step on the footrests/footplates when getting in and out.
►Do not support yourself on the wheel lock when getting in/out.
CAUTION
Incorrect caster wheel position when leaning forward in the wheelchair
Tipping over, falling due to incorrect caster wheel positioning

bility of the wheelchair.
►In order to do so, push the wheelchair backwards until the caster wheels turn forward.
Getting into the wheelchair in combination with transfer from one wheelchair to another is described below.
The wheelchair is designed for persons who normally move around independently in a wheelchair. Hence inde
pendently getting in/transferring is described here. If an assistant is required, the steps described here should be
performed analogously with support:
1) Manoeuvre the wheelchairs such that they are positioned at an angle of approx. 45° to each other (see fig.11).
Ensure that the wheel locks do not become entangled.
2) Engage the wheel locks of the wheelchair currently in use.
3) On the other wheelchair, engage the wheel locks and fold up the footrest (footplate) (see fig.12).
16
Use
Zenit

4) Move your feet from the footplate onto the floor and move forward in the wheelchair (see fig.13).

6.9 Caster wheels and caster forks
CAUTION
Incorrect caster wheel position when leaning forward in the wheelchair
Tipping over, falling due to incorrect caster wheel positioning
►Prior to activities that require you to bend forward in the wheelchair (e.g.tying your shoes), maximise the sta
bility of the wheelchair.
►In order to do so, push the wheelchair backwards until the caster wheels turn forward.
