Adjusting the seat height – front
Figures 24
The seat height at the front can be adjusted using
the methods below.
Moving the bearing housing of the castor
wheel up or down (see page 17).
By moving the bearing housing up, the seat
is lowered, and by moving it down, the seat is
raised.
Moving the castor wheel to a higher or lower
position in the castor wheel fork.
By moving the castor wheel to a higher position
in the castor wheel fork (24A), the seat is lowered,
and by moving the castor wheel to a lower
position, the seat is raised.
Changing to bigger or smaller castor wheels
A smaller castor wheel lowers the seat height,
whilst a bigger castor wheel raises the seat
height. By changing the castor wheel, a smaller
castor wheel will give a smaller turning radius, and
thereby increase the ability to negotiate obstacles
in narrow spaces, and will also give more room
for the legs. A larger castor wheel will increase the
turning radius but will also improve the ability to
negotiate obstacles on uneven surfaces.
Changing to a longer or shorter castor wheel
fork
A shorter castor wheel fork lowers the seat
height, gives a smaller turning radius, and thereby
increases the ability to negotiate obstacles in
narrow spaces, and will also give more room for
the legs. A longer castor wheel fork increases the
seat height, and allows several alternative castor
wheels to be used.
The table on page 31 shows which seat heights
can be achieved by using the methods above.
Note!
Remember to adjust the angle of the castor
wheel when changing the seat height, and to
adjust the brakes when changing the seat height
at the back.
