This adjustment is achieved by means of hexagonal screw head fittings. These locate in the
moving element of the castor housing, and are eccentric about their mounting screw point,
allowing the housing to be located at different angles by turning the hexagon and securing at the
fixing screw at a required setting.
Correct function of the castor is with the spindle vertical or inclined within one degree from vertical
in the trailing direction. When adjusting castor positions it is essential that they are the same for
each side of the wheelchair. After any adjustment, the castor mounting screws should be fully
tightened.
The castor fork has three hole positions for different types of wheel and angle settings. The
standard wheel position for the 190mm castor is in the centre hole. Alternative positions can be
used at the discretion of the authorised rehabilitation engineer (see user guide), but the vertical
alignment of the castor should be maintained for all options by resetting the mounting angles
equally on both sides of the wheelchair.
10.0 FOOTRESTS :
These are detachable, and height adjustable.
The footrest mounting is a single location point on the front tube of the frame. The footrest tube is
a fabricated handed assembly with one mounting plate and a top moulding that inserts into the
frame front tube from above which allows the footrest assembly to lift and be swivelled to one side
when mounted on the wheelchair frame, for occupant
assess to the chair.
