To
adjust the track
proceed as follows:
1. Loosen the aluminium locking nuts on both
sides (AF 41 mm).
Figure 81: Drive wheel bushing and aluminium lock-
ing nut (rear view)
2. Correctly adjust the track by turning the
drive wheel bushing (AF 22 mm). Here it
can be said that: If you turn the drive wheel
bushing in the direction of travel, the track
at the front will become more narrow. The
exact opposite occurs if you turn it counter
to the direction of travel; the track becomes
wider.
3. Make sure that the distance at the front to
the frame on the right and left is the same.
Figure 82: 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. 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) to a tightening torque of 70
Nm.
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 carried out according
to the order and can be subsequently changed
by replacing the drive wheel bushings (with
integrated wheel camber). If you would like to
change the camber, 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.
