4. Measure the distance between the drive
wheels at the front and back again at the
axle height (along the markers) so that the
distance between the rive wheels is not
any larger at the front than at the back.
Apart from that, the distance at the back
may not be more than 5
mm larger that at
the front.

tyres (at axle height), back
5. Once all of the distances are correct, use
an open-ended spanner (AF 22 mm) to
hold the drive wheel bushing in position
and tighten the aluminium locking nuts (AF
41 mm) with a tightening torque of 70
Nm.
18.3 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 carried out according
to the order and can be subsequently changed
by replacing the drive wheel bearings (with in-
tegrated wheel camber). If you want to make a
change to the wheel camber, please contact
your rehabilitation specialist dealer or
PRO ACTIV.
18.4 Tyre pressure
Check the tyre inflation pressure at regular in-
tervals 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 tem-
perature. If the pressure is too high, the tyre
may burst. For this reason, product tyres may
not be exposed to unusually high temperatures
such as in a sauna or under glass in the sum-
mer.
When inflating the tyres, make sure that
the prescribed air pressure is not exceeded.
