4.1.4.1 Removing seat
1. Raise the seat to the highest position. If the wheelchair is equipped
with a fixed seat post or if the seat lift does not work normally
because the batteries are discharged or the adjustment device is
defective, the seat can be raised/lowered manually. See
4.1.1.1 Manually operating the seat lift , Page 17.
2. Switch off the main power switch on the control panel.
3. Remove the cushion from the seat.
4. Remove the seat plates, which are held in place by two screws at the
back edge and two quick-mount clamps at the front. First remove
the screws, then use your hand to carefully push the seat plate from
below to release the quick-mount clamps at the front.
5. Remove the control panel. Loosen the control panel cabling from
its fixing points. Remember how the cabling is positioned; this helps
when you come to re-attach it.
6. On wheelchair equipped with seat tilt, separate the cabling for the
seat angle mechanism at the contact on the cabling. The contact is at
the front right corner of the seat angle mechanism, next to the other
cabling.
7. Remove the four screws that hold the seat in place. The seat can be
mounted in three different positions, depending on the currant seat
depth. Note the position the seat is mounted in for future reference.
8. Lift the seat off the seat lift/seat column.
