necessary, via the slotted channel in the MX2 Back shell (refer to Fig. 8a).
The recommended back height* is approximately 5"-6" (13-15 cm) from
the top of the seat surface (seat cushion or seat pan; Refer to Fig. 8b).
4 Working on one side at a time, loosen the mounting bracket hardware (A),
and slide the MX2 Back shell up/down until the desired back height is
achieved. NOTE: The range of MX2 Back Height Adjustment varies
depending on the height (slot length) on the MX2 Back Shell- see Table 1.0:
5 Tighten the mounting bracket plate/hardware (A) to secure the MX2 back in
place, making certain to maintain the proper mounting pin width/position
(per Fig. 7). Repeat the same back height adjustment on the opposite
mounting bracket.
6 Once all width & height adjustments are finalized, fully secure all hardware.
*Note: The recommended MX2 back height is provided as a guideline
