The
seat angle
, the
front and rear seat
heights
and the
seat depth
can be adjusted
using the
predefined grid of holes and pre-
centred holes
in the clothing guard. To do
this, the two M6 fixing screws (AF 4 mm) need
to be unscrewed on each side. The new de-
sired position is then determined in the grid of
the clothing guard. If only pre-centred holes
are available for the desired positions, these
can be used for positioning by drilling out with
a diameter of 6.1 mm and deburring.
Now position the seat plate at the desired seat
height and depth. Then push the seat plate
sliding block along the seat plate slots so it sits
in front of the desired holes in the clothing
guard. While adjusting, make sure that M6 fix-
ing screws and the seat plate sliding blocks are
positioned symmetrically flush and that the op-
posite M6 fixing screws are in the same posi-
tion in the grid. Afterwards, retighten the M6
fixing screws (AF 4 mm) with a torque of
11 Nm.
Apart from positioning the seat plate in the
clothing guard grid, the seat heights can be ad-
justed by positioning the M6 fixing screws in
slots at a different height position. There are
two
slots at different heights
at each fixing
point for this purpose.

Another way to adjust the seat height is to
flip
the
seat plate
. To do this, unscrew the M6 fix-
ing screws (AF 4 mm) completely, remove the
seat plate and put it back on upside down.
Please make sure that the straight edge re-
mains at the front. In Figure 8, the seat plate is
positioned in the lower slot. Afterwards, re-
tighten the M6 fixing screws (AF 4 mm) with a
torque of 11 Nm.
To make smaller adjustments to the
seat
depth
, the two M6 fixing screws (AF 4 mm) on
each side are loosened slightly and the
seat
plate
is
slid
into the desired position along the
slots
on the seat plate sliding blocks.

seat plate along the slots
After adjusting the seat plate, it may be neces-
sary to adjust the position of the back shell.
Please observe the instructions in Chapter
17.2.
The position of the footrest must be adjusted
whenever the seat height and angle are
changed. When doing so, ensure that there is
enough clearance under the footrest. Experi-
ence shows that this should not be less than
4 cm. You will find more details in Chapter
17.3.
