5.
The wheels, casters, and tires should be checked periodically for cracks and wear, and should be replaced when necessary. Contact a qualified
technician or Invacare customer support at the telephone numbers on the back of this manual.
6.
Periodically adjust wheel locks in correlation to tire wear. Refer to Adjusting Anti-Tippers on page 92.
7.
Regularly check for loose spokes in the rear wheels. If loose, have them adjusted. Contact a qualified technician or Invacare customer support
at the telephone numbers on the back of this manual.
8.
Periodically check handrims to ensure they are secured to the rear wheels. Refer to Replacing Handrims on page 84.
9.
Periodically check caster wheel bearings to make sure they are clean and free from moisture. Use a Teflon
®
lubricant if necessary.
10. Hand grips should be checked monthly for wear/looseness/deterioration. Clean if desired. Replace if looseness or deterioration is found.
11. On a monthly basis, for the 80° and 90° front riggings, check the mounting pin for excessive wear or damage. Replace mounting pin if worn or damaged.
12. Inspect front rigging mounting pin and hardware. Specifically, inspect the mounting screw that secures the mounting pin to the front rigging.
Tighten if mounting screw is loose.
CAUTION
As with any vehicle, the wheels and tires should be checked periodically for cracks and wear, and should be replaced if
damaged.
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.
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.
