The down axle of the front fork must always
be at 90º angle with the floor. A template
is provided with each chair to check the
perpendicularity.
Use a 5 mm allen key and undo the bolt half
a turn (see picture). Then we need a second 5
mm allen key to complete the adjustment. As
you can see in the picture we have to undo
the bolt at the
back and turn
the allen key at
the outside of
the frame until
with the help
of the template
we can measure a 90º angle. The cylinder
that makes the adjustment possible has a
red mark to remember the right position for
our configuration. See the picture on the
right for the right adjustment of the standard
configuration with a 24” wheel at the rear
wheel bracket and a 8” caster wheel. As you can
see the caster wheel is in the lower hole of the
front fork.
Position of the rear wheel in the wheel
bracket
The rear wheel bracket has multiple positions
where the rear wheel can be fixed. The picture
on the left shows the fixation hole for the
standard configuration. With this standard
configuration the seat height at the front of the
wheelchair is 50 cm, and 47 cm at the back.
The seat angle can be varied by fixing the rear
wheel in a different hole of the wheel bracket.
In such a case we have to make sure that the
angle of the down axle of the front fork is at 90º.
