18 |
| warning |
18 |
| Invacare strongly recommends proceeding down ramps or slopes slowly to avoid hard braking or sudden stops. |
18 |
| Be aware that carrying heavy objects on your lap while occupying the wheelchair may adversely affect the stability of the wheelchair, resulting in serious bodily injury to the user, damage to the wheelchair and surrounding property. |
18 |
| This wheelchair has been designed to accommodate one individual. If more than one individual occupies the wheelchair this may adversely affect the stability of the wheelchair, resulting in serious bodily injury to the user and passenger and damage th... |
18 |
| To assure stability and proper operation of your wheelchair, you MUST at all times maintain proper balance. Your wheelchair has been designed to remain upright and stable during normal daily activities as long as you DO NOT move beyond the center of ... |
18 |
| Virtually all activities which involve movement in the wheelchair have an effect on the center of gravity. Invacare recommends using seat positioning straps for additional safety while involved in activities that shift your weight. |
18 |
| DO NOT lean forward out of the wheelchair any further than stability will allow. Make sure casters are pointing in the forward position whenever you lean forward. This can be achieved by advancing the wheelchair and then reversing it in a straight line. |
18 |
| m |
18 |
| warning |

18 |
| Many activities require the wheelchair owner to reach, bend and transfer in and out of the wheelchair. These movements will cause a change to the normal balance, the center of gravity, and the weight distribution of the wheelchair. |
18 |
| To determine and establish your particular safety limits, practice bending, reaching and transferring activities in several combinations in the presence of a qualified health-care professional before attempting active use of wheelchair. |
18 |
| Proper positioning is essential for your safety. When reaching, leaning, bending forward, it is important to use the front casters as a tool to maintain stability and balance. |
18 |
| • Lengthening the wheelbase will increase the stability and maintain standard maneuverability of wheelchair. |
19 |
| • Shortening the wheelbase will decrease the stability, increase the maneuverability and distribute additional weight onto the rear wheels. |

| Reaching, Leaning, and Bending - Forward |
20 |
| 4.3 Coping with Everyday Obstacles |
20 |
| Coping with the irritation of everyday obstacles can be alleviated somewhat by learning how to manage your wheelchair. Keep in mind your center of gravity to maintain stability and balance. |
20 |
| 4.4 A Note to Wheelchair Assistants |
20 |
| When assistance to the wheelchair user is required, remember to use good body mechanics. Keep your back straight and bend your knees whenever tilting the wheelchair or traversing curbs, or other impediments. |
20 |
| m |
20 |
| warning |
20 |
| Do not attempt to lift a wheelchair by lifting on any removable (detachable) parts. Lifting by means of any removable (detachable) parts of a wheelchair may result in injury to the user or damage to the wheelchair. |
20 |
| Also, be aware of any removable (detachable) parts. These MUST NEVER be used to move the wheelchair or as lifting supports, as they may be inadvertently released, resulting in possible injury to the user and/or assistant(s). |
21 |
| When learning a new assistance technique, have an experienced assistant help you before attempting it alone. |

| Maintenance Safety Precautions |
29 |
| m |
29 |
| warning |
29 |
| After ANY adjustments, repair or service and before use, make sure all attaching hardware is tightened securely - otherwise injury or damage may occur. |
29 |
| Replace any labels that are missing, worn, or torn. Refer to Label Locations on page 12 for a listing of the labels and their locations |
29 |
| caution |
29 |
| DO NOT overtighten hardware attaching to the frame. This could cause damage to the frame tubing. |
29 |
| Suggested Maintenance Procedures |
29 |
| 1. Before using your wheelchair, make sure all nuts and bolts are tight. |
29 |
| 2. Check all parts for damage or wear and replace. |
29 |
| 3. Check all parts for proper adjustment. |
29 |
| 4. Keep quick/quad-release axles free of dirt and lint to ensure positive locking and proper operation. Refer to Adjusting Quick-Release Axles on page 67 or Adjusting Quad-Release Handles on page 68. |
29 |
| m |
29 |
| warning |
29 |
| DO NOT use WD-40®, 3-in-1 oil®, or other penetrating lubricants on quick-release axles or camber inserts. Otherwise, binding and/or damage to the wheelchair may occur. |
29 |
| 5. Clean quick-release axles and camber inserts once a week with a Teflon® lubricant. |
30 |
| m |
30 |
| warning |
30 |
| DO NOT use your wheelchair unless it has the proper tire pressure (p.s.i.). |
30 |
| 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. |
30 |
| CAUTION |
30 |
| 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 Replacing/Repairing Rear Wheel Tire/Tube on page 31 and Replacing/Repairing Caster Tire/... |
30 |
| 6. Periodically adjust wheel locks in correlation to tire wear. Refer to Replacing/Adjusting the Wheel Locks on page 63. |
30 |
| i |
30 |
| Tire wear is excessive if: |
30 |
| • Pneumatic Tires - there is missing tread or the tires are bald. |
30 |
| • Urethane Tires - there are cuts, surface defects or the tires are loose on the rims. |
30 |
| • Rubber Tires - 30% or more of the tire has worn away. |
30 |
| Invacare recommends that rear wheel tire/tube and caster tire/tube be replaced every five years. |
30 |
| 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. Replace wheels if spokes are broken. |
30 |
| 8. Ensure that folding back is fully locking into place when back is open. Adjust as needed. |
30 |
| 9. Periodically check handrims to ensure they are secured to the rear wheels. Refer to Handrim Replacement on page 70. |
30 |
| 10. Periodically check caster wheel bearings to make sure they are clean and free from moisture. Use a Teflon® lubricant if necessary. |
30 |
| 11. Check upholstery for sagging, rips or tears and loose or broken fasteners. Replace or tighten as necessary. |
30 |
| 12. Clean upholstery with mild soap and water. |
30 |
| 13. Replace any labels that are missing, worn or torn. |
