When the drive wheels have been adjusted for the user, the caster journal angle must be readjusted.
The threaded axle in each of the two caster heads should be perpendicular to the ground to ensure optimum

fig. 11, item 1).
3) Remove the cap at the top of the caster journal bearing (see fig. 11, item 2).
4) Place the supplied measuring tool (spirit level) on the top surface of the caster journal bearing in the direction
of travel (see fig. 11, item 1).
5) Position the continuously variable caster journal bearing perpendicular to the ground (see fig. 11, item 3).
6) Tighten the Allen head screws to
8 Nm
.
7) Reinstall the caps (see fig. 10, item 1).
→ The caster axle on each of the two caster journal bearings must be positioned vertically (see fig. 10, item 2).
