11 MAINTENANCE
11.1 Cleaning
Periodic cleaning of all surfaces will help maintain the appearance and ensure proper
operation of your wheelchair. All surfaces can be cleaned using warm water and a mild
soap solution. Do not use abrasive cleaners on any surfaces.
11.2 Suggested Maintenance Procedures
1. Before using your wheelchair, make sure all nuts and bolts are tight. Check all parts
for damage or wear and replace them if necessary. Check all parts for proper
adjustment.
2. Keep quick-release axles, if fitted, free of dirt and lint to ensure positive locking and
proper operation. Refer to ADJUSTING THE QUICK-RELEASE AXLE in section 14.9 of
this manual.
3. If applicable, oil quick-release axles at least once (1) a month (3-in-1 oil or
equivalent).
4. Keep wheel-locks free of dirt to ensure they do not get stuck.
WARNING
– If pneumatic tires are used, do not use the wheelchair unless it has the
proper tire pressure (psi). DO NOT over inflate the tires. Failure to follow these
suggestions may cause the tire to explode and cause bodily harm.
5. If tires are pneumatic, recommended tire pressure is listed on the side wall of the tire.
6. The rear wheels and casters should be checked periodically for cracks and wear, and
should be replaced when necessary at your authorized dealer or by a qualified
technician.
7. For wheelchairs with hand rims, periodically check hand rims to ensure they are
secured to the rear wheels.
