Step 2
Place the mechanism on the seat, then the plastic cover over it.

Tips & safety
- Warning: gas cylinder Only trained personnel may replace or repair the seat height adjustment parts (manual p. 9–10).
- Safety casters They brake automatically when no one is sitting in the chair, so it stays where you left it (manual p. 14).
- Adjust the chair Lift the lever for seat height; pull it out to unlock the tilt, push it in to lock. Set the tilt tension under the seat with the Allen key, then keep the key in the pocket by the zip (manual p. 12–13).
