Champion ’08 1.6 Tipping stability
The tipping stability is influenced by the seat angle which is given by the front and rear
seat-to-floor height. Another possibility to influence the tipping stability is to change the
position of the front and rear wheels:
- Adjust the rear wheels position to the adapter plate more to the front or more to the
rear (Chapter 2.10).
- Adjust the position of the front wheel supporter more to the front or more to the
rear (Chapter 2.6).
The chair will be more stable, the further rearwards that the rear wheels are fitted.
1.7 Backrest height (RH)
To adjust the backrest height you must adjust or replace the backrest tubes. (Chap-
