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 Uni-
versal 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 extru-
sions 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 Spe-
cialty Seat, Synergy Seat, or a 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 harness 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 harness so that it cannot be
pinched in the seat hinge.
MANDATORY! Prevent controller
harness damage! Use correct tie-down
points for controller harness. Avoid
routing the controller harness on the
outside of the armrest pad. Route the
harness under the armrest or toward
the inside of the armrest pad. Use
correct tie-down points for the
controller harness to prevent the
harness from getting caught in the
drive tires, pinched in the seat frame,
or damaged when passing through
doorways.
