V. SET UP & USE OF YOUR WHEELCHAIR
W. Spark - Adjusting Frame Width
1. Adjusting Frame Width
To change the width of the frame:
a. Remove the bolts that connect the cross braces and the cross brace extensions (Fig. 38:A)
on both sides of the frame.
NOTE: Remember which hole the bolt (Fig. 39:B) is using in the upper pivot bracket (Fig. 39:C).
b. Remove bolt (Fig. 39:D) from center of cross braces.
c. Slide cross brace extensions in or out to reach the desired overall width. Each frame is avail-
able with three seat widths in 1" increments.
To measure the width, take a measure from the outside of the seat frame on one side and the
outside of the seat frame on the other side.
d. After you locate the desired width, slide the bolt (Fig. 39:B) back through the cross braces
and cross brace extensions on both sides. Then, locate the center hole that corresponds. If
the bolt is in the middle hole of the extension, locate the center hole in the middle.

X. Upholstery Fabric
1. You must immediately replace seat and back upholstery that has worn through and shows
signs of failing. If you fail to do so, the seat or back may fail.
2. The seat sling material will weaken over time. Look for fraying, thin spots, or stretching of
fabrics, especially at edges and seams. This should be done weekly.
3. The repeated action of transferring to your wheelchair will weaken sling material and result
in the need to inspect and replace the seat more often.
4. Be aware that laundering or excess moisture will reduce flame retardation of the fabric.
5. Contact your wheelchair provider if you have concerns about your seat or back, or feel it
needs to be replaced.
WARNING: Failure to comply with these instructions may result in damage to your wheelchair, a
fall or loss of control causing severe injury to the user or others.
