5 SAFETY INSPECTION/TROUBLESHOOTING ƽ CAUTION As with any vehicle, check the wheels and tires periodically for cracks and wear. Replace if damaged. 4. Periodically adjust wheel locks in correlation to tire wear. Refer to Adjusting Wheel Locks on page 41.  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. 5. Periodically check handrims to ensure they are secured to the rear wheels. If loose, have them tightened by a qualified technician. 6. Periodically check caster 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. 7. Hand grips should be checked monthly for wear/looseness/deterioration. Clean if desired. Replace if looseness or deterioration is found. 8. Check upholstery for sagging, rips or tears. Replacing/Repairing Rear Wheel Tire/Tube ƽ WARNING Replacement of solid rubber tires is not recommended. If the solid rubber tire needs repaired, Invacare recommends replacing the complete wheel assembly. Part No. 1148116 27 Invacare® Veranda™Wheelchair
