DUMP (FIGURE 2)
Seat dump is a measurement taken at the rear of the seat
from the horizontal position, and is measured in inches.
Refer to DETAIL "A" of FIGURE 2. The seat dump of the
Spyder can be adjusted in1/2-inch increments, up to 2-1/2-
inches below the front seat-to-floor height.
NOTE: Adjust both rear uprights to the same position.
1. Remove the bolt and locknut securing the rear up-
right to the wheelchair frame.
2. Loosen, but do not remove the front and rear pivot bolt.
NOTE: Loosening the pivot nut allows the back angle to
remain the same in relation to the ground. No adjustment
is necessary to the back angle when adjusting seat dump.
3. Reposition the rear upright up or down and align the
mounting holes in the rear upright with the mounting
holes in the frame until the desired seat dump is
achieved. Refer to the chart below.
