4.10 Reaching, Leaning and Bending - Forward 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. ƽ WARNING 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. Position the front casters so that they are extended as far forward as possible and engage wheel locks. 4.11 Reaching, Bending - Backward ƽ WARNING DO NOT lean over the top of the back upholstery. This will change your center of gravity and may cause you to tip over. Keep hands and fingers clear of moving parts to avoid injury. Position wheelchair as close as possible to the desired object. Point front casters forward to create the longest possible wheelbase. Reach back only as far as your arm will extend without changing your sitting position. 4 SAFETY/HANDLING OF WHEELCHAIRS FIGURE 6 Reaching, Leaning and Bending - Forward FIGURE 7 Reaching, Bending - Backward Part No 1167418 31 Invacare® MyOn™MyOn Jr Wheelchairs

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

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
