Maintenance
Maintenance
(9.9)
• Check the tire pressure every 4 weeks. Check all
of the tires for wear or damage.
• Check the brakes approximately every 4 weeks to
make sure that they are working properly and
easy to use.
• Change tires as you would an ordinary bicycle
tire.
• All of the joints that are critical to safe using your
wheelchair safely are self-locking nuts. Please
check every three months to make sure that all
bolts are secure (See the page on torque). Safety
nuts should only be used once and should be
replaced after multiple uses.
• 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 after use.
• 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 wheel-
chair to your authorized 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.
