SEAT DEPTH ADJUSTMENT
1. Determine the proper seat depth.
2. To change seat depth, undo the hook and loop that
attaches the back panel to the seat panel. (Fig. 4)
3. Relieve fabric tension by partially folding the chair.
4. Unscrew the bolt on the side of the seat rail
(Fig. 5A) and move seat tube to the desired hole
(8, 9 or 10). Refasten the bolt. See seat depth
matrix.
5. Repeat operation on other side of seat.
6. Reattach the seat panel to the back panel.
To Adjust The Back Angle:
1. To adjust the back angle, relative to the seat, consult
the Set-up Matrix.
2. To relocate the back post along the seat rail, loosen
and remove bolts (Fig 4A & Fig 5D) from both sides
of the seat and align the back posts along the seat
rail in the required location.
3. Put bolts back in place and secure the nuts tightly.
