tact the qualified personnel who adjusted your product.
WARNING
Settings outside the safety limits
Risk of falling, tipping of the user
►In certain versions and with certain settings, the wheelchair tends to tip backwards due to its design. The fea
ture is intentional in order to enable users with the corresponding physical preconditions to manoeuvre
quickly and nimbly.

►Always get into the wheelchair from the side, where possible.
CAUTION
Incorrect caster wheel positioning
Risk of falling or tipping when leaning forward in the wheelchair
►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.

Hazards while driving
CAUTION
Travelling without experience
Risk of falling, tipping of the user
►Familiarise yourself with the wheelchair by practicing on level, easy terrain first.

ward or upward slopes, inclines or when overcoming obstacles.
►Always activate the anti-tipper.
CAUTION
Wrong centre of gravity
Risk of tipping or rolling over
►Do not lean too far out of the wheelchair when trying to pick up objects.
►Lean well forward with your upper body when climbing gradients, overcoming obstacles on gradients or on

6.2 Getting into the wheelchair/transfers
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.
Getting into the wheelchair is described here in combination with transfer from one wheelchair to another.
The wheelchair is designed for persons who normally move around in the wheelchair independently. Independently
getting in / transferring is described accordingly. If an assistant is required, the steps described here should be
performed analogously with support:
1) Manoeuvre the wheelchairs so that they are positioned at an angle of approx. 45° degrees to each other (see
Fig.6). Ensure that the brakes / 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.7).
4) Move your feet from the footplate onto the floor and move forward in the wheelchair (see Fig.8).
5) Make the transfer to the 2nd wheelchair (see Fig.9). The method illustrated is one possible way to support
yourself.
NOTE Find the most suitable method for yourself by practising with the help of an assistant.
6) Finally fold the footplate down, place your feet on the footrest and release the wheel locks.
→The wheelchair can now be used.
