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. |
24 |

To assure stability and proper operation of your wheelchair, you must at all times wear your seat positioning strap and maintain proper balance. Your wheelchair has been designed to remain upright and stable during normal daily activities as long as ... |
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 |
4.5 Tipping |
25 |
m |
25 |
Warning |
25 |
DO NOT tip the wheelchair without assistance. |

27 |
3. After the wheelchair has been tilted back to the balance point, the assistant behind the wheelchair backs the wheelchair up against the first step. |
27 |
4. The second assistant (positioned in the front of the wheelchair), with a firm hold on a non-detachable part of the framework, lifts the wheelchair up and on to the next stair above and steadies the wheelchair as the assistant behind the wheelchair... |
27 |
5. The wheelchair should not be lowered until the last stair has been negotiated and the wheelchair has been rolled away from the stairway. |
27 |
6. If necessary, rotate the anti-tippers so the wheels are facing down. |
27 |
Moving Down Stairs |

caution |
29 |
When transferring, position yourself as far back as possible in the seat. This will prevent damaged upholstery and the possibility of the wheelchair tipping forward. |
29 |
i |
29 |
This activity may be performed independently provided you have adequate mobility and upper body strength. |
29 |
1. Position the wheelchair as close as possible along side the seat to which you are transferring, with the front casters parallel to it. |

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. |
