6.4 Castor
Castor, Castor adapter, Castor fork (Fig.6.19)
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:
• 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;
wheels do not turn smoothly.
The optimum adjustment of the castors is required so that
the wheelchair runs in a straight line.
The castor plates must be re-adjusted, and the wheel
locks must be checked every time the rear wheel position
has been altered.
Adjusting the castor
Setting directional stability and fine-tune caster-
height
These are works-settings and require special tools-
please contact your dealer for support.
Adjusting the caster-fork angle
This adjustment is necessary when changing the front- or
rear seat-height.
DANGER!
Failure to adjust the correct angle can result in caster-
flutter, locking caster wheels and injury of the user.
Loosen Allen screw (1) (Fig. 6.19). The caster-fork angle
can now be adjusted to the correct position: the flat
section of the fork must be positioned 90° to the ground.
Use the markings (2) as optical aid for the adjustment.
Once you have set the correct position, then tighten the
Allen screw (1) to the specified torque.
DANGER!
Failure to tighten the Allen screw (1) correctly may result
in unintended movement of the caster-fork and injury of
the user.
