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.
To attach the drive wheels, press the locking
knobs and insert the drive wheels with quick-
release axle into the drive wheel bushings.
When doing this, special attention should be
paid to ensure that the locking knob springs
out again after attaching the wheel, as other-
wise the wheels are not properly secured. You
will know this if you can see the index groove.

axles are locked.

TRAVELER usage instructions
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.

port, large push button
Recommended equipment:
For quadriplegics or people with limited finger
function, a Tetra Clip is available to operate
the quick-release axle lock. The Tetra Clip is a
plastic housing that is screwed onto the outer
side of the drive wheel hub and operated by
means of a push-through pin. The pin has a
red marking on one side (quick release axle
opened) and a green marking on the other side
(quick release axle locked). The pin can be
pushed using the ball of your hand in the direc-
tion of the middle of the drive wheel and
thereby the quick release axle opened or
closed.
