12 |
| DO NOT lean over the top of the back upholstery to reach objects from behind as this may cause the wheelchair to tip over. |
12 |
| DO NOT shift your weight or sitting position toward the direction you are reaching as the wheelchair may tip over. |
12 |
| DO NOT tip the wheelchair without assistance. |
12 |
| DO NOT attempt to stop a moving wheelchair with wheel locks. Wheel locks are not brakes. |
12 |

12 |
| DO NOT operate on roads, streets or highways. |
12 |
| DO NOT climb, go up or down ramps or traverse slopes greater than 9°. |
12 |
| DO NOT attempt to move up or down an incline with a water, ice or oil film. |
12 |
| DO NOT attempt to ride over curbs or obstacles. Doing so may cause your wheelchair to turn over and cause bodily harm or damage to the wheelchair. |
12 |
| DO NOT attempt to lift the wheelchair by 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. |
12 |

| Anti-tippers MUST be used at all times. When outdoors on wet, soft ground or on gravel surfaces, anti-tippers may not provide the same level of protection against tip over. Extra caution MUST be observed when traversing such surfaces. Inasmuch as the... |
13 |
| Engaging the wheel locks may not prevent the wheelchair from moving on all floor surfaces including those that may be wet or slick. ALWAYS exercise caution when transferring into or out of the wheelchair. |
13 |
| Always use the handrims for self-propulsion. Inasmuch as the handrims are an option on this wheelchair (you may order with or without the handrims), Invacare strongly recommends ordering the handrims as an additional safeguard for the wheelchair user. |

20 |
| ALWAYS check hand grips for looseness before using the wheelchair. If loose and/or worn, replace IMMEDIATELY. |
20 |
| 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. |
20 |
| 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... |
20 |
| 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 ... |
20 |
| 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. |
21 |
| 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. |
21 |
| m |
21 |
| Warning |
21 |
| DO NOT attempt to reach objects if you have to move forward in the seat or pick them up from the floor by reaching down between your knees. |
21 |
| The position of the footrest, camber tube, back angle, the tautness of the back upholstery as well as the user's condition are directly related to the wheelchair's stability. Any change to one or any combination of the five may cause the wheelchair t... |
21 |
| 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. |
21 |
| 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. |
21 |
| 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. |
21 |
| • Lengthening the wheelbase will increase the stability and maintain standard maneuverability of wheelchair. |
21 |
| • Shortening the wheelbase will decrease the stability, increase the maneuverability and distribute additional weight onto the rear wheels. |

| 4.3 Coping with Everyday Obstacles |
23 |
| 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. |
23 |
| 4.4 A Note to Wheelchair Assistants |
23 |
| 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. |
23 |
| m |
23 |
| WARNING |
23 |
| 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. |
23 |
| 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). |
