responding height position of the wheel
plates.

3. Position the aluminium locking nuts back
on the drive wheel bushings so that they
rest slightly against the position gates, and
then set the drive wheel track correctly
(see Chapter 21.2).
17.1.1 General instructions
When changing the rear seat height each time:
the wheel track of the drive wheels must
be checked and readjusted if necessary
(see Chapter 21.2).
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 clearance
under the footrest. Experience shows that
this should not be less than 4 cm (see
Chapter 23).
if necessary, the height of the anti-tipping
support may have to be readjusted (see
Chapter 24.3).
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.
