5.16 Seat angle adjustment
The angle of the castor arms must be adjusted
according to the seat angle, which results from
the set seat heights at the front and rear.
This angle must be set so that the axes of the
steering forks (= castor angle) are perpendicular
to the ground.
This adjustment option is used only to compen
-
sate for the seat angle. A castor angle that devi-
ates from 90 ° will always have a negative im-
pact on the wheelchair's driving behaviour.
1.
To adjust the castor angle, loosen the 3
screws on the inside of the frame by a few
turns.
2.
You can now insert a 5 mm Allen key
through the hole in the bottom of the cas-
tor housing and adjust the angle by turning
(1, Fig. 60) (1, Fig. 61).
3.
Then tighten all screws again.
NOTE
For precise adjustment, we recommend using a
90° try square.
