Service manual
Seat
Seat width (SB)
Available seat widths: SB 340 to 480 in 20 mm steps.
Changing the seat width is very complicated. The seat module, the backrest, the real wheel axles and
the footrest have to be replaced.
Seat depth (ST)
Available seat depths: ST 375 to 525 in 25 mm steps.
Changing the seat depth requires the replacement of the complete seat module including the seat
cover and the seat rail and potentially also the seat cushion.
Front seat height (SHv)
The front seat height is dependent on several factors that interact with each other. The size of the rear
wheels determines the height of the sub-structure. In addition to the size and the positioning of the
brackets on the seat module, the frame, seat depth and rear seat height inuence the seat height.
