Maintenance
The maintenance described in this section can be carried out by the user.
Other maintenance work should be carried out by qualified personnel at
your local supplier or at the technical aids centre. For information about
repairs or service, ask the technical aids centre in your area.
Washing the frame
The frame should be regularly washed with mild soapy water. If the frame is
very dirty, a scouring agent may be used. If necessary, the frame can be flushed
using a high-pressure jet spray. Try to avoid spraying directly at the ball bearings.
Dry the wheelchair thoroughly after washing or when it has been out in the rain.
Grease all moving parts if you have used a scouring agent.
Cleaning the seat and backrest covers
The covers can be washed in a washing machine at 60 °C. See the washing
instructions on the various textiles.
Conditions which may damage the wheelchair
The chair should not be used in temperatures below –35 °C or over 60°. No
requirements are specified in connection with humidity and air pressure. No other
requirements are specified for storage.
Screws and nuts
Screws and nuts can loosen over time. Therefore, remember to check and if
necessary tighten them at regular intervals. A screw locking agent such as Blue
Locktite (no. 243) may be used. If a locking nut has been removed, it loses some
of its locking properties and should be replaced.
Lubrication
Moving parts, such as the rails on the sliding seat, should be lubricated as
needed.
Driving wheels
The driving wheels are equipped with spokes. These should be adjusted if they
begin to work loose. Ask a local bicycle dealer or your nearest technical aids
centre.
Quick-release hub for the wheels
The quick-release hub for the driving wheels requires regular inspection. Check
that the ball bearings are working satisfactorily. The release bolt and ball bearings
should be cleaned and lubricated with oil regularly.
