2.7 Replacement of gas spring for back recline
1. Remove cushions and seat plate.
2. Release the gas spring from the back frame by pulling out the pin (6 in Figure 4), and then fold the
back frame forward. Be careful as the back frame is free to fall when then pin is pulled out.
3. Loosen the nut (11) slightly so that the gas spring can be threaded out of the rod (7). Hold all of
the end pieces together so they do not fall apart.
4. Thread the new gas spring into the rod. Check that all pieces are in place and that the nut (11) is
fully threaded on to the gas spring shaft.
5. Adjust the gas spring position in the rod (7) so that the pin (2) is parallel with the bracket (10)
when the spring is pressed (
lightly
) against the release pin of the gas spring. See Figure 4.1.
6. Tighten the nut (13) but not excessively. Turn the gas spring to the correct angle and attach it to
the back frame with the pin (6). Check that the pin snaps into place correctly.
7. Check the back recline function. The cable may need adjustment. Some adjustment for proper
release of the gas spring can even be done by moving the gas spring slightly in the rod.
See also section 3.3 Cable controls for more info.
8. Reassemble the seat plate and cushions.
