Figure 69: Distance at the front to the frame
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. If all the distances are correct, then use an
open-ended spanner (AF 22 mm) to hold
the running wheel bushing in position and
tighten the aluminium locking nut (AF 41
mm) with a tightening torque of 70
Nm.
21.3 Wheel camber
The wheel camber increases the lateral
stability 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
integrated wheel camber). If you want to make
a change to the wheel camber, please contact
your dealer or PRO ACTIV.
21.4 Air pressure
Check the tyre inflation pressure at regular
intervals as well as after extreme influence of
temperature. The maximum and if applicable,
minimum tyre pressure is printed on the side of
the tyre.
If the tyre pressure is too low, then optimal
functionality of the knee lever brake is not
ensured. Apart from that, there is an increased
risk of a flat tyre.
The tyre pressure increase 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
temperatures such as in a sauna or under
glass in the summer.
