6.3 Adjusting the caster wheels
6.3.1 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 cap on the caster wheel adapter using a screwdriver (see fig. 15, item 1).
2) Slightly loosen the Allen screws on the inside of the frame (see fig. 16, item 1).
3) Slightly loosen the Allen screw on the eccentric (see fig. 17, item 1).
4) Position the assembly aid (spirit level) (see fig. 18, item 1).
5) Adjust the positive/negative caster to
90°
on the eccentric disc using a wide slotted screwdriver (see fig. 18,
item 2). The bubble in the spirit level must be in the centre position.
6) Tighten the Allen screw on the eccentric to
8 Nm
.
7) Firmly tighten the Allen screws on the inside of the frame.
8) Attach the protective cap to the caster wheel adapter.

The threaded axle on each of the two caster wheel adapters must be positioned vertically.
