Assembly

Note: This assembly requires technical proficiency.
Preparation: Check that the seat is level, not tilted. Remove all accessories, arm rests, cushions, and drive
wheels. Place the wheelchair on a work bench or similar. Ensure that the wheelchair is in a stable position,
preferably with both castors forward.
Check that the adapter plates and all parts are present. Identify LH and RH parts and place them on each
side of the wheelchair so that they are at hand as needed.

: See Figure
the screws (a) in place to support the seating unit.
The next step requires extreme care. The assembly is made much easier with a helper holding the push
bar to balance the seating unit. If no helper is available the seating unit must be supported so that it does
not fall when the screws are removed. In this case there is a significant risk for personal injury or damage
to the wheelchair (particularly the cables and the gas spring attachment points).
Remove the screws and washers (a). The joint bushing (b) will be re-used. It may remain in place in the
seat frame. The other parts will be replaced.
