From time to time the wheelchair may veer slightly to the right or
left, or the castors may flutter.
This may be caused by the following:
The forward or reverse wheel motion has not been set properly.
The castor angle has not been adjusted properly.
Castor and/or rear wheel air pressure is incorrect; wheels do not
turn smoothly.
The optimum adjustment of the castors is required so that the
wheelchair runs in a straight line. The castors should always be
adjusted by an authorised dealer.
The castor plates must be re-adjusted, and the wheel locks must
be checked any time the rear wheel position has been altered.
Check the setting of the castor adapter (1) by placing a set-
square next to it and looking at it from the front. Make sure that
the adapter is at right angles to the floor. By undoing the screws
(2) and moving the adapter, you can then re-adjust the wheels to
their optimum position, by adjusting the corresponding teeth
segments. Make sure that after any adjustment work, all screws
are tightened correctly (see the page on torque).

The position of the centre of gravity in relation to the rear wheel
is an important factor for easy and comfortable driving. Several
positions are possible. If you move the perforated plate to the
rear (1) in the frame holes (2), the chair is in a safe position, but
at the same time is not so manoeuvrable, as it is when the
perforated plate is positioned further forward.
By moving the axle adapter (3) in the perforated plate, the seat
height of the chair can be adjusted. Make sure that after any
adjustment work, all screws are tightened correctly (see the
page on torque).
CAUTION!
If necessary, the brakes and castors must be re-adjusted.

Camber (Fig.6.21-6.22)
The camber of the chair can be adjusted from 1° to 4°.
Doing this gives increased stability against the wheelchair falling
to the side, and will also improve the wheelchair's
manoeuvrability.
Loosen the screws on the perforated plate (1). Then adjust the
adaptor (2) to the desired angle setting. Then tighten the screws
again (see the page on torque).
Setting the wheel camber increases the overall width of the
wheelchair (each degree adds on approx. 10 mm).
CAUTION!
If necessary, the brakes and castors must be re-adjusted.
