Rear axle positions seat height
Seat height (Fig. 40) can be
adjusted by moving the axle plate
(1) up or down the frame within a
range of 50mm (2") seat height
adjustment. The four bolts (3) and
nuts (4) per axle plate must be
removed and positioned as
required, then tightened to 8-10Nm
torque, using two 10mm A/F spanners.
Both axle plates must be positioned
in the same hole setting on each
side to ensure that the chair is level.
Note:
After changing the seat height
always check:
Toe in/toe out (Fig. 43, page 32)
Angle of castors (Fig. 46, page 34)
Both axles are in identical
positions.
Wheelbase width
The wheelbase width is adjusted by
loosening the inner (1) and outer
28mm A/F axle sleeve nuts (2),
using adjustable spanners, and
positioning the axle sleeve (3)
where required. The nuts must be
tightened using a torque spanner to
45Nm torque (Fig. 41).
Note:
To achieve the narrowest
possible wheelbase the axle
plates may be positioned on the
inside of the frame tubes. Both
axles should be positioned
identically.
