It is mandatory to use a seat cushion on
the seating system. At cold temperatures, the
seat cushion prevents lower abdomens from
undercooling and protects against dirt and
wetness. Moreover, the cushion ensures
uniform pressure distribution for your bottom
and absorbs impacts as well as vibrations.

20.1 Removing and attaching the drive
wheels
Figure 33: Locking knob of the quick-release axle in
the middle of the wheel axle
To
remove the drive wheels
grip through the
spokes around the wheel hub with your fingers.
By pressing the locking knob in the middle of
the wheel axle with your thumb, the wheels
can then be removed.
When
attaching the drive wheels
, the locking
knobs must be pressed and the drive wheels
with quick-release axle must be inserted in the
drive wheel bearings. When doing this, special
attention should be paid to ensure that the
locking knob springs out again after attaching
the wheel, as otherwise the wheels are not
properly secured. You will know this if you can
see the index groove.

Before using the product, check if the
wheels are secured and that the quick release
axles are locked.
20.2 Checking and adjusting the wheel
tracking of the drive wheel
Well adjusted wheel tracking significantly
improves the easy running characteristics of
the product. To
check
the tracking, proceed as
follows:
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.
