6.2.5 Adjusting the handrims

INFORMATION

This section does not apply for double handrims (one-handed operation). The distance to the drive wheel cannot

be changed here.

INFORMATION

This section does not apply to standard wheels.

All handrims are designed for a spacing from the drive wheel of 15 mm (standard setting) and 25 mm (see fig. 11).

1) Completely remove the tyre.

2) Loosen/remove the handrim screw connection from the rim.

3) Tightly screw the handrims onto the rim in narrow or wide installation position (see fig. 12).

4) Completely reinstall the tyre.

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

wheelchair driving characteristics. The caster journal bearings permit continuous adjustment of this angle.

1) Remove the caps (see fig. 13, item 1).

2) Below the caps, slightly loosen the Allen head screws between the caster journal bearing and the frame (see

fig. 14, item 1).

3) Remove the cap at the top of the caster journal bearing (see fig. 14, 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. 14, item 1).

5) Position the continuously variable caster journal bearing perpendicular to the ground (see fig. 14, item 3).

6) Tighten the Allen head screws to 8 Nm.

7) Reinstall the caps (see fig. 13, item 1).

→ The caster axle on each of the two caster journal bearings must be positioned vertically (see fig. 13, item 2).
