Adjustments

6.1.1 Settings during Preassembly

If the seating shell/seating system as well as the back system have already been preassembled, the following chapters
can be omitted:
• Chapter "Adjusting the Seat Width" (see Page 10)
• Chapter "Adjusting the Seat Depth" (see Page 11)
• Chapter "Adjusting the Back Angle" (see Page 11)
• Chapter "Adaptation of the Seating Shell/Seating System" (see Page 12)

6.2 Adjusting the Seat Width

6.2.1 Adjusting the Width of the Main Frame

Within the allowable adjustment range, the width of the main frame can be adapted to the width of the chosen seating
shell or seating system:
1) Remove the seat frame from the main frame (see Page 13).
2) Loosen 4 x Allen head screws on each of the adjustment tubes at the rear (see Fig. 1, item 1) and front (see Fig. 2,
item 2).
3) Adapt the width on the adjustment tubes, preferably making it symmetrical.
INFORMATION: The connection between the adjustment tube and frame always has to be realised on both
sides with 2 Allen head screws (use inner 2 bores).
INFORMATION: If required, an asymmetry of 12.5 mm (1/2") is allowable when adapting the adjustment
tubes. The asymmetry must be on the same side on all adjustment tubes. However, the allowable adjust­
ment range must not be exceeded.
Firmly retighten all Allen head screws to a torque of 10 Nm.
4) Mount the seat frame on the main frame (see Page 13).

6.2.2 Adjusting the Width of the Seat Frame

INFORMATION
► Before adjusting the seat frame, the main frame needs to be adjusted (see the preceding chapter).
► In case of a seating shell/seating system preinstalled at the factory, these settings do not have to be changed.
The width of the seat frame can be adapted to the width of the chosen seating shell or seating system.
1) When using a seat plate: remove the seat plate (see Page 12).
2) Remove the seat frame from the main frame (see Page 13).
3) Loosen 4 x Allen head screws on each of the connecting tubes at the front (see Fig. 3, item 1) and rear (see Fig. 3,
item 2).
4) Loosen 2 x Allen head screws with counter nuts on the connecting tube of the central seat fork (see Fig. 3, item 3).
5) Loosen 2 x Allen head screws with counter nuts on the locking bar (see Fig. 3, item 4).
6) With push bar option: loosen 2 x Allen head screws on the connecting tube (see Fig. 4, item 5).
7) Adjust the width on all connecting tubes, preferably making it symmetrical.
INFORMATION: If required, an asymmetry of 12.5 mm (1/2") is allowable when adapting the connecting
tubes. The asymmetry must be on the same side on all connecting tubes. However, the allowable adjustment
range must not be exceeded.
When using a seat plate: reinstall the seat plate (see Page 12).
8) Tighten all Allen head screws to the following torque values:
