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 seat­
ing shell or seating system:
1) Remove the seat frame from the main frame (see Page 14).
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 adjust­
ment tubes. The asymmetry must be on the same side on all adjustment tubes. However, the allow­
able adjustment 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 14).
