Initial Assembly
Your power chair may require some assembly either before initial use or after transportation. It may also
require disassembly to make some comfort adjustments. Figure 6 details those parts of the power chair
that are designed to be disassembled and assembled by an end user or by a qualified caregiver before
using the product or making comfort adjustments.
NOTE: If your power chair is equipped with a Synergy Seat, or a TRU-Balance® Power Positioning
System, refer to the information provided in separate manuals.
NOTE: Any nylon insert lock nut removed during the disassembly or adjustment of the power
chair must be replaced with a new nut. Nylon insert lock nuts should not be reused as it may
cause damage to the nylon insert, resulting in a less secure fit. Replacement nylon insert lock
nuts are available at local hardware stores or through your Quantum Rehab Provider.
Assembly
Seat Installation
It may be necessary to install the seat either prior to initial operation or after transporting your power
chair. Contour seats are attached to the power base with the Universal Mounting System (UMS). The
UMS consists of universal parts that may be attached to the 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 7.
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 7.
2. Lower the front extrusion onto the front trapeze bar until the seat locks into place.
3. Flip the seat latch safety down.
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 8, 9 or 10.
MANDATORY! Prevent controller harness damage! 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 the correct tie-down points for controller harness to prevent the harness from getting
cuaght in the drive tires, pinching in the seat frame, or damaged when passing through doorways.
5. Plug the controller connector into the rear of the power base. See figure 1.
6. Secure the controller harness to the armrest receiver with wire ties. See figure 9.
