Anti-Tip Tubes
(7.93)
Anti-tip tubes (1) provide additional
safety for inexperienced users
when they are still learning how to
operate their wheelchairs. Anti-tip
tubes (1) prevent a wheelchair from
tipping over backwards. Pushing
the anti-tip tubes (1) will move
them downwards; they can also be
swung forward. An interval of 3 cm
to 5 cm should be maintained be-
tween them and the ground. You
must swing the anti-tip tubes for-
ward when going up and down
large obstacles (such as a curb) to
prevent them from touching the
ground.

Standard Sling
(7.101)
The sling is equipped with a Velcro
fastener on one side; this permits
stepless adjustment of the sling.
To readjust the sling, first fold up
the wheelchair slightly. Then re-
move the screws (1) and pull the
front plugs (2) forward out of the
frame. The sling (3) can then be
slid off of the frame. By un-
fastening the Velcro, the sling can
be readjusted. Reverse this pro-
cedure to reinstall the sling. When
finished, make sure that all screws
have been properly tightened (see
the page on torque).
CAUTION:
For proper safety, at least 50 %
of the Velcro surfaces must
make contact with each other at
all times.
Options – Standard Sling
Crutch Holder
(7.110)
This device permits crutches to be
transported directly on a
wheelchair. It has a Velcro loop (1)
to fasten crutches or other aids.
CAUTION:
Never try to use or even remove
the crutches or other aids while
moving.

Tray
(7.111)
The tray provides a flat surface for
most activities. Before using a tray,
it first has to be adjusted once to
the width of the seat by an autho-
rized dealer. The user must be
sitting in the wheelchair during the
trial run.

Transit Wheels
(7.113)
Transit wheels should be used
wherever your wheelchair would
be too wide if the rear wheels were
used (e.g., in airplanes, buses,
etc.). After the rear wheels have
been removed with the aid of the
quick-release axles, the transit
wheels can immediately be used
to continue riding. The transit
wheels are mounted so that they
are approx. 3 centimeters above
the ground when not in use. They
are thus out of the way when
riding, transporting, or when
tipping to pass over obstacles
(e.g., curbs, steps, etc.).
CAUTION:
Your wheelchair does not have
any wheel locks when the transit
wheels are being used.

Tires and Mounting
(8.1)
Always make sure you that you maintain the correct
tire pressure, as this can have an effect on
wheelchair performance. If the tire pressure is too
low, rolling resistance will increase, requiring more
effort to move the chair forward; low tire pressure
also has a negative impact on maneuverability. If the
tire pressure is too high, the tire could burst. The
correct pressure for a given tire is printed on the
surface of the tire itself. Tires can be mounted the
same way as an ordinary bicycle tire. Before in-
stalling a new inner tube, you should always make
sure that the base of the rim and the interior of the
tire are free of foreign objects. Check the pressure
after mounting or repairing a tire. It is critical to your
safety and to the wheelchair’s performance that
regulation air pressure be maintained and that tires
be in good condition.
