Position the product on a level surface and
secure the product against rolling away.
Measure the axle heights (from the ground to
the drive wheel axle) and write this dimension
onto both tyres at front and back.
Figure 60: Drawing the axle height on the front and
back of both tyres
Afterwards measure the distance between the
drive wheels front and back at the height of the
axles along the markers. Ideally, the distance
between the two drive wheels should be the
same size at the front and back. In general it
can be said that the distance between the drive
wheels at the front may not be larger than at
the back. Apart from that, the distance at the
back may not be more than 5
mm larger that at
the front. If this is not the case, the wheel
tracking needs to be corrected. In this case,
check the correct positioning of the track dis-
tances.

21.3 Wheel camber
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
The wheel camber increases the lateral stabil-
ity of the product but also increases the overall
width of the product.
The wheel camber will be configured as or-
dered and can be subsequently changed by
replacing the camber wedges. If you want to
make a change to the wheel camber, please
contact your rehabilitation specialist dealer or
PRO ACTIV.

21.4 Tyre pressure
Check the tyre inflation pressure at regular
intervals as well as after extreme influence of
temperature (not on solid rubber tyres). The
maximum and if applicable, minimum tyre
pressure is printed on the side of the tyre
.
This should be observed.
If the tyre pressure is too low, the opti-
mum functional capability of the knee lever
brake is not guaranteed, and an excessively
low tyre pressure negatively influences the
driving behaviour. Apart from that, there is an
increased risk of a flat tyre.
The tyre pressure increases with the
temperature. If the pressure is too high, the
tyre may burst. For this reason, product tyres
may not be exposed to unusually high temper-
atures such as in a sauna or under glass in the
summer.
When inflating the tyres, make sure that
the prescribed air pressure is not exceeded.
