Before using the product, check if the
wheels are secured and that the quick release
axles are locked.
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.

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 there-
by the quick release axle opened or closed.

track spacers must always be reinstalled ex-
actly as they were ex-factory upon delivery.
