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 Uni- versal Mounting System (UMS). The UMS consists of universal parts that may be attached to the seat, regard- less of seat width or seat depth. The two main compo- nents 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 11.
NOTE: If your power chair is equipped with a Spe- cialty Seat, Synergy Seat, or a
