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 a pair of trapeze bars that
are mounted to the power base. See figure 11.
NOTE: If your power chair is equipped with a Syn-
ergy Seating System or a Synergy TRU-Balance
Power Positioning System, refer to the information
provided in separate manuals.
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. Tilt the seat back and slide the rear extrusion onto the
rear trapeze bar. See figure 11.
2. Lower the front extrusion onto the front trapeze bar
until the seat locks into place.
3. Flip the seat latch safety down. See figure 11.
WARNING! Make sure the seat latch
safety is flipped down before using your
power chair.
4. Install the controller and route the cable to the back of
the power base. See figure 12.
5. Loosen the rear shroud fasteners and remove the rear
shroud. See figure 6.
6. Plug the controller connector into the power base. See
figure 7.
7. Reinstall the rear shroud and tighten the rear shroud
fasteners. See figure 6.
8. Route the controller cable so that it cannot be pinched
in the seat hinge.
MANDATORY! Prevent controller harness
damage! Use correct tie-down points for
controller harness.
9. Secure the controller cable to the armrest receiver with
wire ties. See figure 13.
