upholstery/back shell as it significantly in-
creases the risk of an adjustment, falling down
or defects.

18.1.1 Adjustment possibilities with
backrests fixed by being bolted on-
to side panels
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
With backrests screwed permanently onto side
panels, there are no possibilities for flexible
backrest adjustment without tools available.

with an "Aluminium side panel", or
with an "Aluminium side panel with
screwed on clothing guard", or
with an "Aluminium side panel with inte-
grated clothing guard".
For this, there are three holes in the rear area
of the side panel at the top and an elongated
hole at the bottom to position the backrest
tubes. To adjust the backrest 5° forwards or
backwards, loosen both M5 fixing screws
(AF 3 mm) with washers on each side and
position the fixing screws with washers in the
desired holes of the side panel at the top and
bottom in the corresponding position in the
elongated hole (same position on the right and
left). Then tighten up the M5 fixing screws
(AF 3 mm) again to 6 Nm and secure them
with thread lock fluid.

18.1.2 Adjustment possibilities with an
adjustable backrest
If equipped with an adjustable and foldable
backrest, the backrest angle can be flexibly
adjusted without using tools and the backrest
can be completely folded away. The angle of
the backrest can be fixed in 7 positions in 5°
steps.
Observe that the centre of gravity is shift-
ed further to the rear by the enlargement of the
angle between the backrest and the seat sys-
tem and thus, the tipping point of the product is
reached much sooner.
