7 Maintenance and service
As the user, you are likely to be the first to notice any damage to the wheelchair. Check the
condition of your wheelchair regularly. If you discover a problem, consult an expert without
delay. The wheelchair should be serviced by a specialist at least once a year.
Before using the wheelchair for the first time and after every service or adjustment it is
essential to check the following:
• Have all nuts, screws and bolts been securely tightened? Self-locking nuts should only be
used once and then replaced.
• Are there any signs of damage or wear and tear?
• Are all the settings correct?
Caution!
Check all screw and bolt connections carefully immediately after carrying out
repairs or adjustments. Any safety nuts that are removed during repairs
should be replaced with new safety nuts when the wheelchair is re-assembled.
7.1 Checks prior to each use
We recommend that you check the following each time you use the wheelchair:
• Check that the brakes are working properly.
• Check that the wheels are functioning properly by testing whether the wheelchair travels
in a straight line.
• Check that all removable parts are securely fixed in place, e.g. armrests, footrests, quick-
release axles, etc.
• Check the wheelchair for visible signs of damage, e.g. damage to the frame, backrest,
seat and backrest upholstery, wheels, footplates, etc.
• Check the seat and backrest for material defects, tears or loss of tension in the material.
7.2 Monthly checks
• Spin each of the wheels when the chair is empty to check if they are turning freely. At
the same time, check whether the wheels come to a slow stop. If the wheels stop
abruptly make sure the hubcaps are correctly fitted. Check whether any dirt has gotten
into the wheel hubs. The service life of the wheels depends on usage. Check the depth of
tread on the tires. There should be at least 1 mm/.04 inches of tread. Defective or worn
tires must be replaced.
• Check that all moving parts, including the folding mechanism, move freely and quietly.
Squeaking sounds suggest there may be damage and the wheelchair should be checked
over by a specialist retailer.
• In order to ensure that the quick-release axle system on the drive wheels continues to
work properly, it should be cleaned regularly with a dry cloth and then oiled.
