If installing Deep Contour Supports, punch out
the two holes located on each side of the shell
as seen in Figure 7. Attach the supports, adjust
their position, and tighten fasteners and weld
STEP 8
Once all the hardware is in place, you can
reposition the Back Cushion (B) in its original
position on the Back Shell (A). Align the
TensionHooks (C) with the wheelchair push
handles and press firmly until they snap into
place. Tighten all parts to 20in-lb (2.3Nm) and
click the four VERSAlocks (I) into position.
This action is illustrated in Figures 8 & 9.
Figure 10 shows the TensionHook secured by
the VERSAlock.
