7.4 Adjusting the caster wheels

7.4.1 Adjusting the caster journal angle

When the drive wheels have been adjusted for the user, the caster journal angle must be adjusted at the caster
wheel adapter.
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) Pull off the protective caps on the caster wheel adapters with the help of a screwdriver (see fig. 17).
2) Slightly loosen the mounting screws on the inside of the frame (see fig. 18; see fig. 19).
3) Slightly loosen the Allen head screw on the eccentric (see fig. 20, item 1).
4) Position the spirit level (see fig. 20, item 2).
5) On the eccentric disc, set the caster angle to 90° with a wide flat screwdriver. The bubble in the spirit level
must be in the centre position (see fig. 20, item 3).
6) Tighten the Allen head screw on the eccentric to 8 Nm (see fig. 20, item 1).
7) Firmly tighten the Allen head screws on the inside of the frame (see fig. 19).
→ The threaded axle on both caster wheel adapters must be positioned vertically.
