4 SAFETY INSPECTION/TROUBLESHOOTING 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, check the wheels and tires periodically for cracks and wear. Replace as recommended. Refer to Replacing/Repairing Rear Wheel Tire/Tube on page 33 or Replacing/Repairing Caster Tire/Tube on page 33. 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. 3. Periodically adjust wheel locks in correlation to tire wear. Refer to Adjusting Patient Operated Wheel Locks on page 55. 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. 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. 6. Hand grips should be checked monthly for wear/looseness/deterioration. Clean if desired. Replace if looseness or deterioration is found. 7. Check upholstery for sagging, rips or tears. Invacare® Tracer IV®Heavy Duty/Extra Wide Wheelchair 32 Part No. 1110558
