    DO NOT lean over the top of the back upholstery to reach objects from behind as this may  cause the wheelchair to tip over. DO NOT shift your weight or sitting position toward the direction you are reaching as the  wheelchair may tip over. DO NOT tip the wheelchair without assistance. DO NOT attempt to stop a moving wheelchair with wheel locks. Wheel locks are not  brakes. NEVER leave an unoccupied wheelchair on an incline. 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. Also be certain the wheel locks are engaged to prevent the wheels from  moving. DO NOT operate on roads, streets or highways. DO NOT climb, go up or down ramps or traverse slopes greater than 9°. DO NOT attempt to move up or down an incline with a water, ice or oil film. 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. 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. DO NOT stand on the frame of the wheelchair. Check all Allen screws that secure the footrest/raised footrest system to the wheelchair  frame before using the wheelchair, especially if engaging in any contact sport. 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 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 an additional safeguard for  the wheelchair user. Unless otherwise noted, all service and adjustments should be performed while the  wheelchair is unoccupied. ™ Crossfire T6A Wheelchair Part No 1134343...

Tire Pressure and Information 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 on the sidewall of the tire. Replacement of the tire or tube MUST be performed by a qualified technician. 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 and the warranty is void.

    SECTION 6—BACK Back Angle Adjustment NOTE: For this procedure, refer to FIGURE 6.2 on page 32 and FIGURE 6.3 on page 33. NOTE: The numbers on the back angle plate are intended to define the resulting back angle of a  chair that has 2 inch seat drop (at 17 inch depth) and that is measured relative to true vertical with  the chair sitting on a level surface. The plus (+) sign increases the back angle and the minus (‐) sign  decreases the back angle. The resulting back angle will vary somewhat depending on your chair  configuration. Refer to FIGURE 6.3 on page 33 to see these settings converted into back angle  relative to the seat. NOTE: Perform this procedure on both sides of the wheelchair at the same time. 1. Fold down the back. Refer to Unfolding/Folding the Back on page 30. 2.

    Anti-tippers MUST be attached at all times. Inasmuch as the anti-tippers are an option on this wheelchair (you may order it with or without the anti-tippers), Invacare strongly recommends ordering the anti-tippers as an additional safeguard for the wheelchair user.

  • Page 63: Replacing Anti-Tipper

    SECTION 10—ANTI-TIPPER Replacing Anti-tipper WARNING When anti-tippers are used, anti-tippers MUST be adjusted to maintain a 1-1/2 to 2-inch clearance between the bottom of the anti-tipper wheels and the ground/floor. This spacing should ALWAYS be checked whenever adjust- ments/changes are made to the wheelchair. Failure to maintain proper spacing may result in the chair tipping over backward causing serious injury or property damage.
