INFORMATION
The markings that are visible when looking at the wheelchair or caster wheel adapter from the front are relevant
for the adjustments described below. The setting in the range up to ±10.5° (long marking line) is shown in the fol
lowing.
By moving the tenon jointing wheel on the caster wheel adapter, the caster wheel journal angle can be corrected in
1.5° increments starting from the zero position (see fig. 19) (scale value 1 corresponds to 1.5°, scale value 2 cor
responds to 3° (see fig. 20), etc.):
•
Long marking line (see fig. 20): settings in the range of 0 to ±10.5°
•
Short marking lines (see fig. 21): settings in the extended range from ±12°

1) Loosen the Allen head screw on the caster wheel adapter (see fig. 22) and remove the cover.
2) Loosen the mounting screw for the caster wheel journal angle (see fig. 23) until the tenon jointing wheel on one
side can be loosened from the caster wheel adapter and moves freely on one side (see fig. 24).
3) Set the expected appropriate angle (the long marking line on the retainer is applicable). Push the tenon jointing
wheel back into the retainer on one side.
4) Loosen the other side of the tenon jointing wheel from the retainer. Turn the caster wheel adapter until the long
marking line also indicates the same scale position on the tenon jointing wheel (see fig. 25).
5) Slightly tighten the mounting screw for the caster wheel journal angle (see fig. 23) and, by applying the sup
plied assembly aid, check whether the angle in the direction of travel is close to 90° (see fig. 26, item 1/2). If
this is not the case, correct it again (see starting at step 2).
6) Also check the perpendicular position of the threaded axle crosswise to the direction of travel:
→ To do so, set a spirit level onto the caster head (see fig. 27, item 1) and check the perpendicular position
(see fig. 27, item 2).
→ If necessary, also slightly loosen the mounting screw of the caster wheel adapter (see fig. 27, item 3). Move
the threaded axle into the perpendicular position by hand.
7) Tighten the mounting screw for the caster wheel journal angle to 30 Nm (see fig. 23). Tighten the mounting
screw of the caster wheel adapter to 30 Nm (see fig. 27, item 3).
8) Put on the cover and tighten the Allen head screw (see fig. 22).
9) For the caster head on the opposite side, set the tenon jointing wheel to the same scale value.
