17.1.5 General instructions
When changing the rear seat height each time:
the brakes must be readjusted (see Chap-
ter 25).
the caster wheel axles must be readjusted
(see Chapter 22.4).
the backrest angle may have to be reposi-
tioned (see Chapter 18.1).
make sure that there is sufficient ground
clearance under the footrest. Experience
shows that this should not be less than 4
cm (see Chapter 23).
17.2 Adjusting the seat height at the
front / angle of seat
If the seat height has to be adjusted, the angle
of the seat or the front seat height can be ad-
justed. This setting is carried out via the posi-
tion of the caster wheels in the caster wheel
fork and the caster fork size.
17.2.1 Adapting by positioning the caster
wheels in the caster fork
Adjusting the front seat height or angle of seat
can be carried out via the positioning of the
caster wheel in the caster fork. Generally, the
caster forks have three possible positions that
can be used to change the front seat height in
steps of 15 mm.
If the seat inclination or the front seat
height are to be increased, the caster
wheel is mounted in a lower position in the
caster fork.
If the seat inclination or the front seat
height are to be reduced, the caster wheel
is mounted in a higher position in the cast-
er fork.

positioning the caster wheel and its effect on the
front seat height
The instructions for disassembly and assembly
of the caster wheels can be found in Chapter
22.1.
17.2.2 Adaptation by replacing the caster
fork
If the adjustment range of the existing caster
fork is insufficient, the next larger or smaller
one can be used.
In doing so, the bottom position of the fork size
1 is equivalent to the top position of fork size 2
and the bottom position of fork size 2 to the top
position of fork size 3.
