As an option it is also possible to choose a
foot plate which can be folded up towards the
back. If this angle is to be adjusted, then the
procedure is the same as above, however after
competing the adjustment work, the M6 clamp
screws (AF 5 mm) need to be secured with
thread lock fluid.
Measures need to be taken to ensure
there is sufficient ground clearance under the
foot rest. Experience shows that this should
not be less than 4 cm.
16.6 Adjusting the tipping point
The tipping point can be adjusted by adjusting
the seat plate and back shell. You will find
descriptions on this in Chapters 16.1 and 16.2.
An optimal tipping behaviour of the prod-
uct is attained if the hollow axle of the drive
wheels is close to the body's centre of gravity
(as a general rule, slightly in front of the hips).
A product adjusted like this can be driven with
little effort and it also makes it possible to
manage a slightly uneven surface or edges by
tipping slightly. Driving on the two rear wheels
(doing a wheelie) is relatively easy to learn.
Inexperienced wheelchair users are prevented
from tipping over backwards by anti-tippers.
Although shifting the seat system forwards
will counteract the tipping danger, it also
makes it more difficult to turn, steer and tilt the
product. In any case, the setting should be
made to suit your individual requirements and
ability to ensure you can drive your chair
safely.

17.1 Removing and attaching the drive
wheels
Figure 14: Locking knob in the middle of the wheel
axle
To
remove the drive wheels
grip through the
spokes around the wheel hub with your fingers.
By pressing the locking knob in the middle of
the wheel axle with your thumb, the wheels
can then easily be removed.
When
attaching the drive wheels
the locking
knob also has to be pressed. Special attention
should be paid here to ensure that the knob
springs out again after attaching the wheel as
otherwise it is not secured. You will know that if
you can see the index groove.
