    If you are unable to understand the Warnings, Cautions or Instructions, contact a healthcare professional, dealer or technical personnel before attempting to use this equipment. Otherwise, injury or damage may occur. Information for Healthcare Professionals/Assistants The Orbit wheelchair MUST be operated by a healthcare professional or assistant when  in ANY reclined position. Make sure the patient is properly positioned in the wheelchair before reclining or  inclining (reverse recline) to maintain maximum stability and safety.

  • Page 14: Anti-Tippers

    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 Part No. 1073955...

  • Page 15: Tire Pressure

    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 Orbit...

  • Page 16: Section 2-Safety/Handling Of Wheelchairs

    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 position- ing belt only.

    Any change to one or any combina- tion of the nine may cause the wheelchair to decrease in stability. These adjust- ments 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 ...

    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  FIGURE 2.2 Reaching and Leaning your arm will extend without changing  Backwards your sitting position. Tipping WARNING 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 Part No. 1073955...
  • Page 19 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  FIGURE 2.4 Method 2 - Wheelchair pulled backward far enough for the front  Without Step Tubes casters to clear the edge of the curb. ™ Part No. 1073955 Orbit...

    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.

  • Page 21: Escalators

    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  FIGURE 2.6 Transferring To and From transfer board if at all possible. Other Seats ™ Part No. 1073955 Orbit...
