hardware is tightened securely. Otherwise injury or damage may result.

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.
CAUTION
As with any vehicle, the rear wheels, casters and tires should be checked periodi-
cally for cracks and wear, and should be replaced if damaged.
2. The rear wheels, casters and tires should be checked periodically for cracks and wear,
and should be replaced by a qualified technician if damaged.
NOTE: Tire wear is excessive if:
• Pneumatic Tires - there is missing tread or the tires are bald.
• Urethane Tires - there are cuts, surface defects or the tires are loose on the rims.
• Rubber Tires - 30% or more of the tire has worn away.
NOTE: Invacare recommends that tires and casters be replaced every five years.
3. Periodically adjust wheel locks in correlation to tire wear. Refer to Adjusting Patient
Operated Wheel Locks on page 45.
4. Periodically check handrims to ensure they are secured to the rear wheels. If loose,
have them tightened by a qualified technician.
5. Periodically check caster and rear wheel bearings to make sure they are clean and free
from moisture. Use a Teflon
®
lubricant if necessary.
ƽ WARNING
When cleaning rear cane or hand grip areas use only a clean towel lightly dampened
with cool water. Verify that grips are dry prior to use. Use of soap or ammonia
based cleaning solutions will result in the hand grips sliding off the cane assembly.
Failure to observe this warning may result in injury to the user or bystanders.
