The instructions for replacing the caster forks
can be found in Chapter 22.3.
17.2.3 General instructions
When changing the angle of seat or front seat
height each time:
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).
17.3 Adjusting the tipping point
Optimum product tipping behaviour
is
achieved when the axle mount of the drive
wheels is close to the body centre of gravity. A
product adjusted like this can be driven with
little effort and it also makes it possible to
manage a slightly uneven surface or edges by
tipping slightly.
Driving on both drive wheels (doing a wheelie)
is relatively easy to learn. Inexperienced
wheelchair users must be prevented from tip-
ping over backwards by means of anti-tipping
supports. In any case, the setting should be
made to suit the wheelchair user's individual
requirements and abilities to ensure safe oper-
ation.
Setting the tipping point
is carried out by
changing the positioning of the drive wheel
bushings in the wheel plates.

To adjust the tipping position, first remove the
drive wheels via the quick release axles (see
Chapter 21.1), so that you have direct access
to the wheel plates. Then proceed as follows:
1. Loosen the inner steel fastening nuts (AF
30 mm) on both sides.
