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. Check all parts for proper adjustment.
ƽ WARNING
DO NOT use the wheelchair unless it has the proper tire pressure (p.s.i.). DO NOT
overinflate the tires. Failure to follow these instructions may cause the tire to
explode and cause bodily harm.
2. If tires are pneumatic, recommended tire pressure is listed on the sidewall of the tire.
CAUTION
As with any vehicle, the rear wheels, casters and tires should be checked periodi-
cally for cracks and wear, and should be replaced.
3. The rear wheels, casters and tires should be checked periodically for cracks and wear,
and should be replaced by a qualified technician.
4. Periodically check handrims to ensure they are secured to the rear wheels. If loose,
have them tightened by a qualified technician.
5. Periodically adjust wheel locks as tires wear. Refer to Using/Adjusting Disk Wheel
Locks on page 54.
6. Periodically check caster and rear wheel bearings to make sure they are clean and free
from moisture. Use a Teflon
®
lubricant if necessary.
