1. Remove the rear wheels, fold the backrest forward and place the
wheelchair on its back.
2. Loosen the screws
A
for the front bracket on both sides.
3. If you can set the desired seat height using the existing seat brace
B
, loosen the screw
C
and remove screw and washer
D
and the
connecting bar E .
4. If you require a new seat brace, remove the existing one and the
connecting bar
E and loosely fix the new seat brace with spacer
F , washer and nut to the frame using screw C .
5. Slide the seat brace against the rear bracket
G
so that the
required holes overlap.
6. Insert the connecting bar
E
and fix it with screw
D
.
7. Carry out the same setting on both sides.
8. Reinstall the rear wheels, fold up the backrest and check the
position of the seat brace

results in a change to the seat angle. It may be necessary to
correspondingly adjust the front seat-to-floor height (FSTF) or
the backrest angle.
