17.3.3 Angle adjustment of the footplate
The angle of the footrest support plate on the
fixed foot support
can be set by unscrewing
the M6 fastening clamp screws (AF 5 mm) on
the lower side of the footrest support plate.
When the angle adjustment is completed,
tighten the M6 fastening clamp screws (AF
5 mm) again to 5 Nm. This tightening torque
should not be exceeded as higher tightening
torques can damage the clamp.

As an option, it is also possible to choose a
footplate support
that can be
folded up to-
wards the rear
. If the angle of these is to be
adjusted, in addition to the M6 fastening clamp
screws (AF 5 mm) on the footrest support
plate, the M6 fastening clamp screws (AF
4 mm) of the footplate stops must also be loos-
ened. Now the angle of the footplate support
and the footplate stops can be adjusted. Then
tighten the M6 fastening clamp screws (AF
5 mm) on the footrest support plate so that the
footrest support plate with the footplate support
can be rotated around the tube. Depending on
the requirements of the wheelchair user, this
tightening torque corresponds to a guide value
of 3 Nm. The M6 fastening clamp screws (AF
5 mm) on the footrest support plate must be
secured with screw locking fluid. The M6 fas-
tening clamp screws (AF 4 mm) on the foot-
plate stops are tightened with 11 Nm.

Ensure when setting the lower leg length,
that no strong pressure is produced between
the underneath of the lower leg of the wheel-
chair user and the edge of the seating system.
Make sure the clearance under the foot-
rest is sufficient. Experience shows that this
should not be less than 4 cm. This must be ob-
served for the angle adjustment of the footplate
and when setting the lower leg length.
17.4 Adjusting the tipping point
Optimum product tipping behaviour
is
achieved when the axle mount of the drive
wheels is close to the body centre of gravity. A
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.
