IV. ASSEMBLY
SEAT INSTALLATION
It may be necessary to install the seat either prior to initial
operation or after transporting your power chair. Most seats
are attached to the power base with the Universal Mount-
ing System (UMS). The UMS consists of universal parts
that may be attached to any medium-back or high-back
seat, regardless of seat width or seat depth. The two main
components are aluminum extrusions mounted to the seat
base. These extrusions attach to the power seat base (see
figure 12) or to a pair of trapeze bars that are mounted to
the power base (see figure 13).
WARNING! Do not pick up the seat frame
by the armrests. They are free to pivot,
and you may lose control of the seat if
they do so.
To install the seat:
1. Raise the seat up 2 in. (5.08 cm) to allow for sufficient
clearance (power seat only).
2. Tilt the seat back and slide the rear extrusion onto the power
seat frame or rear trapeze bar. See figure 12 or 13.
3. Lower the front extrusion onto the power seat base or
front trapeze bar until the seat locks into place.
4. Flip the seat latch safety down.
WARNING! Make sure the seat latch
safety is flipped down before using your
power chair.
5. Install the controller into one of the armrests. See V.
“Comfort Adjustments.”
6. Turn the rear shroud fasteners one-quarter turn in any
direction.
7. Remove the rear shroud.
8. Plug the motor connectors, the charger inhibit connec-
tor, and the battery connector into the power base. See
figure 8.
9. Reinstall the rear shroud and tighten the rear shroud
fasteners.
10. Route the controller cable so that it cannot be pinched
in the seat hinge.
11. Secure the controller cable to the armrest receiver with
one or more wire ties.
MANDATORY! Prevent controller harness
damage! Use correct tie-down points for
controller harness.
