3.11.3 Adjusting the Caster Wheel Journal Angle
WARNING
Damage to the eccentric during adjustment work
Loss of the caster fork
►
When changing the position of the caster head on the frame, check the M8 interior thread on the eccentric for
damage and replace the eccentric if necessary.
The threaded axle in the caster wheel adapter should be perpendicular to the ground to ensure optimum rolling
behaviour of the wheelchair. The caster wheel adapter permits a continuous adjustment of this angle.
1) Remove the protective cap.
2) Slightly loosen the Allen head screw on the eccentric (see fig. 113).
3) Slightly loosen the Allen head screws on the inside of the frame (see fig. 114).
4) Position the spirit level (see fig. 115, item 1).
5) Adjust the caster angle to 90° with a wide flat screwdriver. The spirit level must be in the centre position to do
so (see fig. 115, item 2).
6) Tighten the Allen head screw on the eccentric to
8 Nm
(CLT: 5.5 Nm)
(see fig. 116).
7) Tighten the Allen head screws on the inside of the frame to
23 Nm
.

The threaded axle on both caster wheel adapters must be positioned vertically.
