Figure 49: Drawing the axle height on the front and
back of both tyres of the running wheels
Afterwards measure the distance between the
running wheels front and back at the height of
the axles along the markers. Ideally, the
distance between both running wheels should
be the same size at the front and back. In
general, it can be said that the distance
between the running wheels at the front and
back may not be larger 5 mm. If this is not the
case, the wheel tracking needs to be
corrected.

tyres (at axle height), back
To
adjust the track
proceed as follows:
1. Loosen the aluminium locking nuts on both
sides (AF 41 mm).

locking nut, product view from behind
2. Correctly adjust the track by turning the
drive wheel bushing (AF 24 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.
When turning against the direction of
travel, the behaviour is exactly the
opposite.
3. Make sure that the distance at the front to
the frame on the right and left is the same.
