IV. ASSEMBLY
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 authorized Pride Provider.
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. If your power chair is equipped with a
Synergy Seat, 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.
