Castors
Setting the Castor, Castor adapter & Castor
fork
If the wheelchair veers slightly to the right or left, or the
castors flutter, it may be caused by one or more of the
following:
• Forward and/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; the wheels do not turn sufficiently freely.
The optimum adjustment of the castors is required so that
the wheelchair runs in a straight line.
Castors should always be adjusted by an authorised
dealer. The castor plates must be re-adjusted, and the
wheel receiver must be checked every time the rear wheel
position has been altered.
Adjusting the castor adapter
To ensure that both forks are set parallel, simply count the
teeth visible on both sides. After setting the castor fork,
the teeth will guarantee a secure position, allowing an
adjustment of 16° in 2° increments (Fig. 6.25).
Use the flat side on the front of the castor fork to check for
a right-angled position to the ground.
The patented design allows the castor fork to be turned,
so that it can be reset at right-angles to the ground when
the seat angle is changed.
Setting the directional stability
Release the Allen screws (1) on the underside of the fork.
You can then remove the screws (2). You can now turn
the black socket (3) left or right.
Left – chair pulls to the left
Right – chair pulls to the right
Then re-tighten the screw (2). Please set a 90° angle from
the fork to the floor.
Then re-tighten the screw (1). (Fig. 6.26).
