18 Drive wheels
18.1 Removing and attaching the drive
wheels
Figure 24: 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.
The wheels can be unlocked and removed by
pressing and holding the locking knob at the
centre of the wheel axle with your thumb.
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.
Figure 25: Quick release axle with index groove
The quick-release axle is equipped with the
small standard locking knobs (see previous fig-
ure) as standard. The
quick-release axle with
operation support and large push button
can be equipped as an option. The sequence
for removing and attaching the drive wheels is
identical with this option.
