MAINTENANCE
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.
All of the joints that are critical to safe using your wheelchair safely are self-locking.
Please check every three months to make sure that all bolts are secure (See the page
on torque). Nylock nuts should only be used once and should be replaced after each
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 after use.
Depending on the frequency and type of use, we recommend taking your wheelchair 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.
