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. “ComfortAdjustments.”

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.
