6.1 Maintenance
CAUTION!
–
DO NOT overtighten hardware attaching to the
frame. This could cause damage to the frame tubing.
Suggested Maintenance Procedures
1.
Before using your wheelchair, make sure all nuts and bolts are
tight.
2.
Check all parts for damage or wear and replace.
3.
Check all parts for proper adjustment.
WARNING!
–
DO NOT use your wheelchair unless it has the
proper tire pressure (p.s.i.).
–
DO NOT overinflate the tires. Failure to follow
these suggestions may cause the tire to explode
and cause bodily harm. The recommended tire
pressure is on the sidewall of the tire.
CAUTION!
–
As with any vehicle, the wheels and tires
should be checked periodically for cracks and
wear, and should be replaced if damaged.
Replace as recommended, refer to 5.15
Replacing/Adjusting the Wheel Locks, page 75 and
5.10 Repairing/Replacing Rear Wheel, Tire/Tube,
page 68.
4.
The rear wheels, casters and tires should be checked periodically
for cacks and wear, and should be replaced by a qualified
technician if damaged.
5.
Periodically adjust wheel locks in correlation to tire wear. Refer
to 5.15 Replacing/Adjusting the Wheel Locks, page 75.
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.
Invacare recommends that rear wheel tire/tube
and caster tire/tube be replaced every five years.
6.
Periodically check handrims to ensure they are secured to the
rear wheels. Refer to 5.9 Handrim Replacement, page 67.
7.
Periodically check caster wheel bearings to make sure they
are clean and free from moisture. Use a Teflon
®
lubricant if
necessary.
8.
Check upholstery for sagging, rips or tears.
9.
Clean upholstery with mild soap and water.
10. Hand grips should be checked monthly for wear/looseness/dete-
rioration. Clean if desired. Replace if looseness or deterioration
is found.
11. Replace any labels that are missing, worn or torn.
Replacing/Repairing Rear Wheel Tire/Tube
WARNING!
–
Replacement of solid urethane tires is not
recommended. If the solid urethane tire needs
repaired, Invacare recommends replacing the
complete wheel assembly.
