Disassembly, complete

NOTE:
• It is not absolutely necessary to follow each and every operational step indicated here. The
compression spring and the Bowden wire, for instance, can be mounted or dismounted without
having first to remove the entire backframe.
• Mark or write down the exact locations of the locking screws and counter nuts (16) before detaching
the Bowden wire (22) / the Bowden covering (23).
• The Bowden wire (22) is provided with final caps (24) on both ends (24), which might have to be
pinched off before the disassembly.
• The adjusting lever (28) is housed in the seat frame and locked with a starlock cap (35). To detach
the lever, the seat cushion and the seat plate should be removed first. See chapt. 9.12. in this respect.
• If there is a headrest, then remove the headrest first. See chapter 9.1. in this respect.
• Remove quick-release bolt (12) at the lower part of the support bracket (30).
• Loosen nut (21), located at the upper part of the back frame tube (6), completely and detach together with
washer (19).
• Support the compression spring (13) with your hand, remove screw (18) with washer (19) and bushing (20),
and detach compression spring together with the entire fork-shaped piece (14) and put aside.
• Loosen nuts (11), located at the lower part of the support bracket (30), and detach together with washers
(10).
• Support the back frame tube (6) with your hand and remove screws (7) with washers (8 and 10) from the
support bracket (18). Then detach the back frame tube.
• Detach safety belt (34) from the back frame tube (6).
• Press bushings (9) outwards from the bushing seats
in the back frame tube.
• Loosen tapping screws with caps (5) completely and detach the back belt (4) from the back frame tube (6)
or press the back padding (1) out of the back frame tube
(6).
• If necessary, remove the countersunk tapping screws (2)
and detach the clamping pieces (3).
• Rotate the compression spring (13) out of the fork-shaped piece (14).
• Loosen clamping screws (26) and nuts (27) to free the Bowden wire (22).
• Loosen counter nuts and locking screws (16) and detach the Bowden wire (22) with its covering (23) from
the fork-shaped piece (13) and the Bowden wire receptacle (25).
• Pinch off the final caps (24) and pull the Bowden wire (22) from its covering (23).
• Lift off the Starlock cap (35), loosen screw (17) and detach the adjusting lever (28) together with the Bowden
wire receptacle (25) from the seat frame.
• If necessary, loosen nuts (33) completely and detach together with washers (31).
• If necessary, hold the support bracket (18) with your hand, remove screws (32) with washers (31) and detach
support bracket (18) from the seat frame.
Assembly
• Proceed with the assembly in the reverse order.

NOTE:
• When assemblying, the compression spring must be screwed into the fork-shape piece up to the limit
stop.
• The Bowden wire must be adjusted in a way that, with the compression spring screwed in, the flat link
in the fork-shaped piece has a play of about 15 mm when the adjusting level is moved.
• After a new Bowden wire has been pulled in, the final caps must be squeezed off.
• Insert the back paddings (1) carefully in order not to damage the clamping pieces (plastic).

NOTE:
The bushings can only be removed from
the inside to the outside.

NOTE:
The back padding can be removed
even if the back frame tube is mounted.
CAUTION:
Do not remove support bracket (18) completely, as
otherwise the seat frame will only be supported by the
threaded spindle or the actuator of the seat
inclination adjustment and thus will become instable.
As to the disassembly of the support bracket, see
chapter 9.14.
