2.8 Change to fixed back angle
The gas spring can be replaced with a Fixed back connector (Figure 5) for a fixed back angle. The back
angle can be set between approximately 90° and 105°. Other angles are possible on request.
The replacement is done as follows:
1. Remove the seat cushion 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. Remove the cable as follows: Fully loosen the nut (4). Take the wire housing (5) out of the bracket
(10) by pulling the end of the housing sideways to bring the wire out. Remove the wire nipple (1)
from the pin (2).
4. Remove the gas spring from the seat frame by removing a circlip (8 in Figure 4) and then pulling
or knocking out the pin (11). Be careful when removing the circlip. If it is opened too far it will be
damaged and must be discarded.
5. Assemble the fixed back connector to the seat frame with the same pin and circlips.
NOTE
: check
that the circlips are undamaged.
6. Adjust the length of the fixed back connector so that it gives the desired back angle. Secure it by
tightening the nut (Figure 5).
The control lever for back recline then has no function. This can be handled in 2 ways:
1. The lever can remain in place. The cable should then be bound up and pinned in place under the
wheelchair. It may be confusing for users to have a lever with no function.
2. The lever and cable can be removed from the cable control. The hole that is left in the cable
control should then be covered with a plug. A plug is included in the conversion kit, see Assembly
instructions

2.9 Replacement of back frame
1. Remove back cushion and disassemble backrest
(Flexi-back or Solid back) and any accessories.
2. Remove all clips (2 in Figure 6) that hold the cables in
place on the back frame.
3. Remove the push bar (entire unit) by removing the 2
screws (1) and pulling it fully out of the back frame.
Be very careful to not damage the cables.
4. Release the gas spring at the back by pulling out the
pin (4), fold the back frame forward.
5. Take apart the screw connections on each side (3)
and remove the back frame.
6. Assemble the new back frame by following the same
steps in reverse order. Be careful that the screw
connections with their bushings are assembled
correctly. See Figure 2.
It is very important that the cables are clipped in place
correctly. See section 3.3.1.
