wheels
Figure 67: 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.
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.
Figure 68: Quick release axle with index groove
The quick-release axle is equipped with the
small standard locking knobs (see previous
figure) as standard. The
quick-release axle
with operation support and large push but-
ton
can be equipped as an option. The se-
quence for removing and attaching the drive
wheels is identical with this option.

Before using the product, check if the
wheels are secured and that the quick release
axles are locked.
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 there-
by the quick release axle opened or closed.
