6.5 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. 6.5.1).
Use the flat side on the front of the castor fork to check for a right-
angled position to the ground, (Fig.6.5.2).
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.
CAUTION!
Some of the screws used during manufacturing are coated with
thread-locking fluid (blue dot on the thread) and can only be adjusted
up to 3 times before they need to be replaced by new thread-locking
screws. Alternatively, the screws can be re-mounted using Loctite™
243 threadlocker.
