6.0 Tyres and Mounting
Solid rubber tyres are standard.
With pneumatic tyres always make sure that the tyres have the
correct air pressure, as otherwise the performance of the
wheelchair may be affected. If the tyre pressure is too low, rolling
resistance will increase, requiring more effort to move the chair
forward. Low tyre pressure also has a negative impact on
manoeuvrability. If the tyre pressure is too high, the tyre could
burst. The correct pressure for a given tyre is printed on the
surface of the tyre itself.
Tyres are mounted the same way as an ordinary bicycle tyre.
before installing a new inner tube, you should always make sure
that the base of the rim and the interior of the tyre are free of
foreign objects. Check the pressure after mounting or repairing a
tyre. It is critical to your safety and to the wheelchair's
performance that regulation air pressure be maintained and that
tyres be in good condition.
7.0 Maintenance and care
• Check the tyre pressure every 4 weeks. Check all tyres for
wear and damage.
• Check the brakes approximately every 4 weeks to make sure
that they are working properly and are easy to use.
• Change tyres as you would an ordinary bicycle tyre.
• All of the joints that are critical to using your wheelchair safely
are self-locking nuts. Please check every three months to make
sure that all bolts are secure (see the section on torque). Safety
nuts should only be used once and should be replaced after use.
• Please use only mild household cleansers when your
wheelchair is dirty. use only soap and water when cleaning the
seat upholstery.
• If your wheelchair should ever get wet, please dry it afterwards.
• A small amount of sewing-machine oil should be applied to
quick-release axles approximately every 8 weeks. Depending on
the frequency and type of use, we recommend taking your
wheelchair to your authorised dealer every 6 months to have it
inspected by trained personnel.
CAUTION !
Sand and sea water (or salt in the winter) can damage the
bearings of the front and rear wheels. Clean the wheelchair
thoroughly after exposure.
The following parts can be removed and sent back to the
manufacturer/dealer for repair:
• Rear wheels
• Armrest
• Footrest holder
• Anti-Tip tubes
These components are available as spare parts. For further
information, please see the spare parts catalogue.
Hygiene measures when being re-used:
Prior to the wheelchair being re-used, it must be carefully
prepared. All surfaces which come into contact with the user
must be treated with a disinfection spray.
To do this, you must use a disinfectant from the DGHm list, e.g.
Antifect Liquid (Schülke & Mayr) for rapid alcohol-based
disinfection for medical products and medical devices, which
must be disinfected quickly.
Please take into account the manufacturer's instructions for the
disinfectant you are using.
In general, a complete disinfection cannot be guaranteed on
seams. We therefore recommend that you dispose of seat and
back slings to avoid microbacterial contamination with active
agents according to § 6 infection protection law.
8.0 Disposal / Recycling of materials
If the wheelchair has been made available to you free of charge,
then it does not belong to you. If it is no longer required, then
follow the instructions to return it as given by the organisation
that made the wheelchair available to you.
In the following section, there is a description of the materials
used on the wheelchair, in view of the disposal or recycling of
the wheelchair and its packaging.
Particular regulations with regard to disposal or recycling may be
in force locally and these must be taken into account when
performing disposal. (This can include the cleaning or
decontamination of the wheelchair prior to disposal).
Aluminium: Castor forks, wheels, sideguards for the chassis,
armrest frame, footrest, push handles
Steel: Fixing points, quick-release axle
Plastic: Handles, tube stoppers, castors, footplates, armpads
and 12" wheel/tyre
Packaging: Plastic bags made of soft polyethylene, cardboard
Upholstery: Woven polyester with PVC coatings and expanded
combustion modified foam.
Disposal or recycling should be carried out by a disposal
company or at a public disposal point. You can also return your
wheelchair to your dealer for disposal.
9.0 Trouble-shooting
Wheelchair pulls to one side
• Check tyre pressure
• Check to make sure wheel turns easily (bearings, axle)
• Check the castor angle
• Check to make sure both castors are making proper contact
with the ground
Castors begin to wobble
• Check the castor angle
• Check to make sure all bolts are secure; tighten if necessary
(see the section on torque)
• Check to make sure both castors are making proper contact
with the ground
Wheelchair / Cross-tube assembly does not snap into
position in the seat saddle
• Chair is still new, i.e., the seat or backrest upholstery is still
very stiff. This will improve with time.
Wheelchair is difficult to fold up
• Adjustable backrest upholstery is too stiff. Loosen it
accordingly.
Wheelchair squeaks and rattles
• Check to make sure all bolts are secure; tighten if necessary
(see the section on torque)
• Apply small amount of lubrication to spots where movable parts
come into contact with one another
Wheelchair begins to wobble
• Check angle at which castors are set
• Check tyre pressure
• Check to see if rear wheels are adjusted differently
