• The "standard" side panel can be folded towards the drive (see fig.23).
• The "clothing protector" side panel can be swung back (see fig.24) and folded down (see fig.25).

Use the 647G829 service manual if the retrofitting of a wheelbase extension becomes necessary in the course of an
initial fitting.

6.3 Adjusting the caster wheels
6.3.1 Adjusting the caster journal angle
WARNING
Damage to the eccentric during adjustment work
Loss of the caster fork
► When changing the position of the caster head on the frame, check the M8 interior thread on the eccentric for
damage and replace the eccentric if necessary.
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 both caster wheel adapters should be perpendicular to the ground to ensure optimum wheel
chair driving characteristics. The caster wheel adapters permit continuous adjustment of this angle.

1) Lift off the plastic cover on the inner side of the frame (not illustrated).
2) Slightly loosen the hexagon head screws on the inner side of the frame (see fig.26, item1/2). If necessary,
loosen and move the front screw (see fig.26, item1).
3) Remove the protective cap (see fig.27, item1).
4) Slightly loosen the Allen head screw on the eccentric (see fig.27, item2).
