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.

    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.

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.

  • Page 60: Section 10-Anti-Tipper

    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 61: 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 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.
