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 a pair of trapeze bars that are mounted to the
power base. If your power chair is equipped with an optional seating system, please 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, resulting in personal injury or damage to the chair.
To install the seat:
1. Set the trapeze bars to the desired height. To change the trapeze bar height, see V. “Comfort Adjustments.”
2. Tilt the seat back and slide the rear extrusion onto the rear trapeze bar. See figure 11.
3. Lower the front extrusion onto the front trapeze bar until the seat locks into place.
4. Flip the seat latch safety down. See figure 12.
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. Plug the controller cable into the connector on the electronics tray. See figure 6.
7. Plug the power elevating seat switch cable (if so equipped) into the connector on the electronics tray.
8. Secure the controller cable to the armrest receiver with one or more wire ties.
9. Route the cable to ensure that the cable cannot be pinched in the seat hinge.
