SECTION 1—GENERAL GUIDELINES 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. Invacare products are specifically designed and manufactured for use in conjunction with Invacare accessories. Accessories designed by other manufacturers have not been tested by Invacare and are not recommended for use with Invacare products. 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. 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 Top End strongly recommends ordering the seat positioning strap as an additional safeguard for the wheelchair user. The seat positioning strap is a positioning ...
SECTION 1—GENERAL GUIDELINES 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. DO NOT use the footplate as a platform when getting in or out of the wheelchair. 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. Weight Limitation Invacareʹs Top End Crossfire T6 and Crossfire Titanium wheelchairs have a weight limitation of 250 lbs. ™ Crossfire Series Wheelchairs Part No 1134872...

SECTION 2—SAFE HANDLING 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. 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.
SECTION 2—SAFE HANDLING 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 tilting the wheelchair or traversing curbs, or other impediments. WARNING 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. Also, be aware of any removable (detachable) parts.

SECTION 6—BACK SECTION 6—BACK WARNING ALWAYS perform these procedures in the presence of an assistant. 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 wheelchairs stability. Any change to one or any combination of the five may cause the wheelchair to decrease in stability.
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. Loosen the jam nut on the placement screw located at the bottom of the back cane (Detail “A”). 3. Tighten the placement screw so that the screw and jam nut are snug against the bottom of the back cane (Detail “B”). 4. Remove the mounting screw that secures the adjustment square to the back angle plate (Details “A” and“C”). 5. Remove the adjustment square from the back angle plate (Detail “C”). NOTE: Note the indent on the adjustment square. When the adjustment square is positioned in the back angle plate, the number that is located directly next to the indent will be back angle relative to true vertical. One side of the adjustment square provides back angles of ‐8°, 0° and ‐4°. Flip the adjustment square over to obtain back angles of 8°, 4° and 0° (FIGURE 6.3). WARNING If the adjustment square is installed into the back angle plate so that a number does not appear next to the indent, DO NOT use this position, otherwise injury will occur.

NOTE: As the wheel lock handle is pulled upwards, the wheel lock will engage and then disengage the wheel.
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.
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 adjustments/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.
