24 |
| DO NOT attempt to lift a wheelchair by lifting on any removable (detachable) parts. Lifting by means of any removable (detachable) parts of the wheelchair may result in injury to the user or damage to the wheelchair. |
24 |
| ALWAYS check hand grips for looseness before using the wheelchair. If loose and/or worn, replace IMMEDIATELY. |
24 |
| DO NOT climb, go up, or down ramps or traverse slopes greater than 9°. |
24 |
| Invacare strongly recommends proceeding down ramps or slopes slowly to avoid hard braking or sudden stops. |
24 |
| DO NOT leave elevating legrests in the fully extended position when proceeding down ramps or slopes. |
24 |
| 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. |

25 |
| 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. |
25 |
| DO NOT lean forward out of the wheelchair any further than the length of the armrests. Make sure the 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 s... |
25 |
| 4.3 Coping with Everyday Obstacles |
25 |
| 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. |
25 |
| 4.4 A Note to Wheelchair Assistants |
25 |
| 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. |
25 |
| Also, be aware of detachable parts such as arms or legrests. 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). |
25 |
| When learning a new assistance technique, have an experienced assistant help you before attempting it alone. |
25 |

25 |
| m |
25 |
| Warning |
25 |
| DO NOT tip the wheelchair without assistance. |

65 |
| Warning |
65 |
| After ANY adjustments, repair or service and before use, make sure all attaching hardware is tightened securely - otherwise injury or damage may occur. |
65 |
| caution |
65 |
| DO NOT overtighten hardware attaching to the frame. This could cause damage to the frame tubing. |
65 |
| Suggested Maintenance Procedures |
65 |
| 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. |
65 |
| 2. 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 95. |
65 |
| m |
65 |
| Warning |
65 |
| Do Not use WD-40, 3-in-1 oil, or other penetrating lubricants on quick-release axles. Otherwise, binding and/or damage to the wheelchair may occur. |
65 |
| 3. Clean quick-release axles once a week with a Teflon lubricant. |
65 |
| m |
65 |
| Warning |
65 |
| DO NOT use your wheelchair unless it has the proper tire pressure (p.s.i.). |
65 |
| 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. |
65 |
| 4. Recommended tire pressure is listed on the sidewall of the tire. |
65 |
| m |
66 |
| caution |
66 |
| As with any vehicle, the wheels and tires should be checked periodically for cracks and wear, and should be replaced if damaged. |
66 |
| 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. |
66 |
| 6. Periodically adjust wheel locks in correlation to tire wear. Refer to Adjusting Anti-Tippers on page 104. |
66 |
| i |
66 |
| Tire wear is excessive if: |
66 |
| • Pneumatic Tires - there is missing tread or the tires are bald. |
66 |
| • Urethane Tires - there are cuts, surface defects or the tires are loose on the rims. |
66 |
| • Rubber Tires - 30% or more of the tire has worn away. |
66 |
| Invacare recommends that rear wheel tire/tube and caster tire/tube be replaced every five years. |
66 |
| 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. |
66 |
| 8. Periodically check handrims to ensure they are secured to the rear wheels. Refer to Replacing Handrims on page 96. |
