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 Mounting
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 frame (see
figure 11) or to a pair of trapeze bars that are mounted to
the power base (see figure 12).
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, resulting in personal injury
or damage to the chair.
To install the seat:
1. Raise the power elevating seat actuator up 2 in. to al-
low for sufficient clearance.
2. Tilt the seat back and slide the rear extrusion onto the
power seat frame or rear trapeze bar.
3. Lower the front extrusion onto the power seat frame or
front trapeze bar until the seat locks into place.
4. Flip the seat latch safety down. See figure 11.
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. Loosen the rear shroud fasteners and remove the rear
shroud.
7. Route the controller connector to the back of the power
base and secure the controller cable to the armrest
receiver with wire ties.
8. Plug the controller connectors into the power pod and
connect the battery connector. See figure 7.
9. Reinstall the rear shroud and tighten the fasteners.
