If you want to return the footrest to the stand-
ard position again, push it back forwards to the
standard position.
To adjust the length of the footrest support
tubes or adapt the lower leg length, the M6
fastening clamp screws (with polymer dry lock-
ing coating, AF 4 mm) must be unscrewed on
both outer sides of the lower leg tubes. The
lower leg length can now be adjusted along the
notches. Make sure that the same notch is
used on both sides.
A large adjustment range is available for a
shorter lower leg length. If a longer lower leg
length is desired, it can usually be extended by
2 cm with the existing lower leg tube. If a
greater extension is desired, longer lower leg
tubes can be obtained from PRO ACTIV.
Once the lower leg length is adjusted, fix it in
position by inserting the M6 fastening clamp
screws (with polymer dry locking coating, AF
4 mm) on both sides and tightening them to
7 Nm.

Note:
With a V-shaped product frame or with a larger
lower leg width at the top than the bottom and
footrest support tubes that do not run parallel,
it is necessary to relieve the footrest support
tube tension in the footrest support plate result-
ing from longitudinal adjustment. In this case,
the M6 fastening clamp screws (AF 5 mm) on
the footrest support plate therefore have to be

length. View the procedure in Chapter 23.1.
23.6 Safety instructions
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.

24.1 Anti-tipping support, pivotable
To minimise the risk of tipping backwards unin-
tentionally, anti-tipping supports are available
as accessories. The anti-tipping supports are
adapted to the axle tube via anti-tipping sup-
port adapters and can be swivelled under the
frame using a spring system.

To overcome an obstacle, the anti-tipping sup-
