INITIAL ASSEMBLY
Your power chair may require some assembly either before initial use or after transportation.
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 Specialist.
Seat Installation
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. See figure 10.
NOTE: If your power chair is equipped with a Specialty Seat, Synergy Seat, or TRU-Balance Power Position-
ing 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.
