SECTION 1 GENERAL GUIDELINES Anti-Tippers Anti tippers MUST be attached at all times. Inasmuch as the anti tippers are an option on this wheelchair (you may order with or without the anti tippers), Invacare strongly recommends ordering the anti tippers as a safeguard for the wheelchair user. ALWAYS use anti tippers. When outdoors on wet, soft ground or on gravel surfaces, anti tippers may not provide the same level of protection against tipover. Extra caution must be observed when traversing such surfaces. Operating Information After ANY adjustments, repair or service and before use, make sure all attaching hardware is tightened securely otherwise injury or damage may result. Unless otherwise noted, all service and adjustment should be performed while the wheelchair is unoccupied. To determine and establish your particular safety limits, practice bending, reaching and transferring activities in several combinations in the presence of a qualified healthcare professional before attempting active use of the wheelchair. When cleaning rear cane or hand grip areas use only a clean towel lightly dampened with cool water. Verify that grips are dry prior to use. Use of soap or ammonia based cleaning solutions will result in the hand grips sliding off the cane assembly. Failure to observe this warning may result in injury to the user or bystanders. If the wheelchair is exposed to extreme temperature (above 100 F or below 32 F), high humidity and/or becomes wet, prior to use, ensure that the handgrips do not twist on the handle. Otherwise, damage or injury may occur. Avoid storing or using the wheelchair near open flame or combustible products. Serious injury or damage to property may result. ALWAYS keep hands and fingers clear of moving parts to avoid injury. DO NOT traverse, climb or go down ramps or slopes greater than 9. DO NOT attempt to move up or down an incline with a water, ice or oil film. DO NOT operate on roads, streets or highways. DO NOT attempt to ride over curbs or obstacles. Doing so may cause your wheelchair to tip over and cause bodily harm to you or damage to the wheelchair. DO NOT attempt to reach objects if you have to move forward in the seat. DO NOT attempt to reach objects if you have to pick them up from the floor by reaching down between your knees. DO NOT lean over the top of the back upholstery to reach objects behind you, as this may cause the wheelchair to tip over. DO NOT shift your weight or sitting position toward direction you are reaching as the wheelchair may tip over. Orbit 14 Part No. 1073955
SECTION 1 GENERAL GUIDELINES DO NOT attempt to stop a moving wheelchair with wheel locks. Wheel locks are not brakes. DO NOT tip the wheelchair without assistance. DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur. Before attempting to transfer in or out of the wheelchair, every precaution should be taken to reduce the gap distance. Turn both casters parallel to the object you are transferring onto. When transferring to and from the wheelchair, ALWAYS engage both wheel locks. DO NOT attempt to lift the wheelchair by 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. DO NOT stand on the frame of the wheelchair. DO NOT use the footplate as a platform. When getting in or out of the wheelchair, make sure that the footplates are in the upward position. ALWAYS wear your seat positioning strap. Inasmuch as the seat positioning strap is an option on this wheelchair (you may order with or without the seat positioning strap), Invacare strongly recommends ordering the seat positioning strap as an additional safeguard for the wheelchair user. The seat positioning strap is a positioning belt only. It is not designed for use as a safety device withstanding high stress loads such as auto or aircraft safety belts. If signs of wear appear, belt must be replaced immediately. 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. Tire Pressure DO NOT use your wheelchair unless it has the proper tire pressure (P.S.I.). 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 listed on the side wall of the tire. Weight Training Invacare does not recommend the use of its wheelchairs as a weight training apparatus. Invacare wheelchairs have not been designed or tested as a seat for any kind of weight training. If occupant uses said wheelchair as a weight training apparatus, Invacare shall not be liable for bodily injury or damage to the wheelchair and the warranty is void. Weight Limitation The Orbit wheelchair has a weight limitation of 150 lbs. Part No. 1073955 15 Orbit
SECTION 2 SAFETY/HANDLING OF WHEELCHAIRS SECTION 2 SAFETY/HANDLING OF WHEELCHAIRS Safety/Handling of Wheelchairs Safety and handling of the wheelchair require the close attention of the wheelchair user as well as the assistant. This manual points out the most common procedures and techniques involved in the safe operation and maintenance of the wheelchair. It is important to practice and master these safe techniques until you are comfortable in maneuvering around the frequently encountered architectural barriers. Use this information only as a basic guide. The techniques that are discussed on the following pages have been used successfully by many. Individual wheelchair users often develop skills to deal with daily living activities that may differ from those described in this manual. Invacare recognizes and encourages each individual to try what works best for him/her in overcoming architectural obstacles that they may encounter. However, all warnings and cautions given in this manual MUST be heeded. Techniques in this manual are a starting point for the new wheelchair user and assistant with safety as the most important consideration for all. Stability and Balance ALWAYS wear your seat positioning strap. Inasmuch as the seat positioning strap is an option on this wheelchair (you may order with or without the seat positioning strap), Invacare strongly recommends ordering the seat positioning strap as an additional safeguard for the wheelchair user. The seat positioning strap is a positioning belt only. It is not designed for use as a safety device withstanding high stress loads such as auto or aircraft safety belts. If signs of wear appear, belt MUST be replaced immediately. To assure stability and proper operation of your wheelchair, you MUST maintain proper balance at all times. 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 gravity. Virtually all activities which involve movement in the wheelchair have an effect on the center of gravity. Invacare recommends using seat/chest positioning straps for additional safety while involved in activities that shift your weight. 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 straight line. Orbit 16 Part No. 1073955
Coping With Everyday Obstacles SECTION 2 SAFETY/HANDLING OF WHEELCHAIRS 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. A Note to Wheelchair Assistants When assistance to the wheelchair user is required, remember to use good body mechanics. Keep your back straight and bend your knees whenever tipping the wheelchair or traversing curbs, or other impediments. DO NOT attempt to lift the wheelchair by 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. If the wheelchair is exposed to extreme temperature (above 100 F or below 32 F), high humidity and/or becomes wet, prior to use, ensure handgrips do not twist on the wheelchair s handle otherwise damage or injury may occur. Also, be aware of detachable parts such as armrests 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). When learning a new assistance technique, have an experienced assistant help you before attempting it alone. 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. The seat height, seat depth, back angle, pivot point of seat frame, seating system, caster position, size and position of the rear wheels, as well as the user condition directly relate to the stability of the wheelchair. Any change to one or any combination of the nine may cause the wheelchair to decrease in stability. These adjustments must be performed by an authorized Invacare dealer or qualified technician. 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. To determine and establish your particular safety limits, practice bending, reaching and transferring activities in several combinations in the presence of a qualified healthcare professional before attempting active use of the wheelchair. Proper positioning is essential for your safety. When reaching, leaning, or bending forward, it is important to use the front casters as a tool to maintain stability and balance. Part No. 1073955 17 Orbit
SECTION 2 SAFETY/HANDLING OF WHEELCHAIRS Reaching, Leaning and Bending Forward 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. NOTE: For this procedure, refer to FIGURE 2.1. Position the front casters so that they are extended as far forward as possible and engage wheel locks. Reaching and Leaning Backwards DO NOT lean over the top of the back upholstery to reach objects behind you, as this may cause the wheelchair to tip over. FIGURE 2.1 Reaching, Leaning and Bending Forward NOTE: For this procedure, refer to FIGURE 2.2. 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. Tipping FIGURE 2.2 Reaching and Leaning Backwards DO NOT tip the wheelchair without assistance. When tipping the wheelchair, an assistant should grasp the back of the wheelchair on a non removable (non detachable) part. Inform the wheelchair occupant before tipping the wheelchair and remind him/her to lean back. Be sure the occupant s feet and hands are clear of all wheels and/or pinch points. After mastering the techniques of tipping the wheelchair, use one of the following methods to tackle curbs, short stairs, etc. Orbit 18 Part No. 1073955
Method 1 - Wheelchair With Step Tubes SECTION 2 SAFETY/HANDLING OF WHEELCHAIRS NOTE: For this procedure, refer to FIGURE 2.3. Place foot on the step tube and begin to tilt the wheelchair toward you. Apply a continuous downward motion until the balance point is achieved and the front casters clear the curb. At this point, the assistant will feel a difference in the weight distribution. When lowering the front casters of the wheelchair, DO NOT let the wheelchair drop the last few inches to the ground. This could result in injury to the occupant and/or damage to the wheelchair. Roll the wheelchair forward and slowly lower the front of the wheelchair in one continuous movement onto the sidewalk. Push the wheelchair forward until the rear wheels roll up and over the curb. Step Tube FIGURE 2.3 Method 1 - Wheelchair With Step Tubes Method 2 - Wheelchair Without Step Tubes ALWAYS check hand grips for looseness before using the wheelchair. If loose and/or worn, replace immediately. NOTE: For this procedure, refer to FIGURE 2.4. This method requires two assistants. The second assistant should be positioned at the front of the wheelchair lifting upward on a non removable (non detachable) part of the wheelchair frame when lifting the wheelchair and stabilizing the wheelchair when the wheelchair is being lowered to the ground. The first assistant should stand on the sidewalk and turn the wheelchair so that the rear wheels are against the curb. Turn the anti tippers so the anti tip wheels are pointing up. The wheelchair should be tilted back to the balance point and, in one continuous upward movement, the rear wheels should be pulled up and over the curb. DO NOT return the front casters to the ground until the wheelchair has been pulled backward far enough for the front casters to clear the edge of the curb. FIGURE 2.4 Method 2 - Wheelchair Without Step Tubes Part No. 1073955 19 Orbit
SECTION 2 SAFETY/HANDLING OF WHEELCHAIRS When lowering the front casters of the wheelchair, DO NOT let the wheelchair drop the last few inches to the ground. This could result in injury to the occupant and/or damage to the wheelchair. Roll the wheelchair backward and slowly lower the wheelchair in one continuous movement. Turn the anti tippers so the anti tip wheels are facing down. Stairways ALWAYS wear your seat positioning strap. Inasmuch as the seat positioning strap is an option on this wheelchair (you may order with or without the seat positioning strap), Invacare strongly recommends ordering the seat positioning strap as an additional safeguard for the wheelchair user. The seat positioning strap is a positioning belt only. It is not designed for use as a safety device withstanding high stress loads such as auto or aircraft safety belts. If signs of wear appear, belt MUST be replaced immediately. 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. ALWAYS check hand grips for looseness before using the wheelchair. If loose and/or worn, replace immediately. Extreme caution is advised when it is necessary to move an occupied wheelchair up or down the stairs. Invacare recommends that, if possible, the user be removed from the wheelchair prior to moving. Invacare recommends using two assistants and making thorough preparations. Make sure to use only secure, non-detachable parts for hand-held supports. NOTE: For this procedure, refer to FIGURE 2.5. Follow this procedure for moving the wheelchair between floors when an elevator is not available: 1. If necessary, rotate the anti tippers so the wheels are facing up. 2. After the wheelchair has been tilted back to the balance point, one assistant (in the rear) backs the wheelchair up against the first step, while securely grasping a non removable (non detachable) part of the wheelchair for leverage. FIGURE 2.5 Stairways Orbit 20 Part No. 1073955
SECTION 2 SAFETY/HANDLING OF WHEELCHAIRS 3. The second assistant, with a firm hold on a non detachable part of the framework, lifts the wheelchair up and over the stair and steadies the wheelchair as the first assistant places one foot on the next stair and repeats STEP 1. 4. The wheelchair should not be lowered until the last stair has been negotiated and the wheelchair has been rolled away from the stairway. 5. If necessary, rotate the anti tippers so the wheels are facing down. Escalators DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur. Transferring To and From Other Seats Before attempting to transfer in or out of the wheelchair, every precaution should be taken to reduce the gap distance. Turn both casters parallel to the object you are transferring onto. Also be certain the wheel locks are engaged to help prevent the wheels from moving. CAUTION When transferring, position yourself as far back as possible in the seat. This will help prevent damaged upholstery and the possibility of the wheelchair tipping forward. NOTE: For this procedure, refer to FIGURE 2.6. NOTE: This activity may be performed independently provided you have adequate mobility and upper body strength. Position the wheelchair as close as possible alongside the seat to which you are transferring, with the front casters pointing parallel to it. Remove or flip up the armrest. Engage wheel locks. Swing away or remove front rigging. Shift body weight into seat with transfer. During independent transfer, little or no seat platform will be beneath you. Use a transfer board if at all possible. FIGURE 2.6 Transferring To and From Other Seats Part No. 1073955 21 Orbit
