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 instal-
ling 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.
Wheelchair pulls to one side (9.1)
• Check tire pressure
• Check to make sure wheel turns easily
(bearings, axle)
• Check angles of casters
• Check to make sure both casters are making pro-
per contact with the ground
Casters begin to wobble (9.2)
• Check angle of casters
• Check to make sure all bolts are secure; tighten if
necessary (See the page on torque)
• Check to make sure both casters are making
proper contact with the ground
Wheelchair / Cross-tube assembly does not
snap into position in the seat saddle
(9.3)
• Chair is still new, i.e., the seat or backrest
upholstery is still very stiff. This will improve with
continued use.
Wheelchair is difficult to fold up (9.5)
• Adjustable backrest upholstery is too stiff; loosen
it accordingly.
Wheelchair squeaks and rattles (9.6)
• Check to make sure bolts are secure; tighten if
necessary (see the page on torque).
• Apply small amount of lubrication to spots where
movable parts come in contact with one another
Wheelchair begins to wobble (9.7)
• Check angle at which casters are set
• Check tire pressure
• Check to see if rear wheels are adjusted
differently
Possible Problems
Tires and Mounting
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 authori-
zed dealer. The user must be sit-
ting in the wheelchair during the
trial run.
Options – Tray

Stabilizing Bar (7.112)
This bar is used to stabilize the
backrest. To be able to fold up
your wheelchair, unscrew the
knobs (1) from the push handles
and remove the stabilizing bar;
now you can easily fold up the
wheelchair. To reinstall the stabili-
zing bar, the knobs must be reins-
erted and tightly screwed so that
the bar sits firmly in position.

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 tip-
ping 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.
