product adjusted like this can be driven with lit-
tle effort and it also makes it possible to man-
age a slightly uneven surface or edges by tip-
ping slightly. Driving on both drive wheels (do-
ing a wheelie) is relatively easy to learn. Inex-
perienced wheelchair users must be prevented
from tipping over backwards by means of anti-
tipping supports. In any case, the setting
should be made to suit the wheelchair user's
individual requirements and abilities to ensure
safe operation.
Setting the tipping point is carried out by
changing the positioning of the drive wheel
bushings in the wheel plates.

1. To adjust the tipping position, first remove
the drive wheels via the quick release ax-
les (see Chapter 22.1), so that you have
direct access to the wheel plates. Then
proceed as follows: Loosen the inner steel
fastening nuts (AF 30 mm) on both sides.

2. Now slide the drive wheel bushings along
the slots in the wheel plates to the desired
tipping point position. Make sure that the
two drive wheel bushings on the right and
left are in exactly the same tipping point
position. The scale on the front of the
wheel plates can be used as a guide.
