3. Remove the three fixing screws (AF 5 mm)
on both wheel plates.
Figure 16: M6 fixing screws (view from bottom and
inner side of product)
4. Now set the wheel plates at the desired
tipping position on both sides of the frame.
Take care that the wheel plates on the
right and left sides are installed at the
same tipping point position.
If you have short inlets in the frame, using
the long M6 screws that you have previ-
ously screwed into the thread from behind,
you have to position this accurately behind
the wheel plates so that the tipping point
positions in the frame and thread rest ac-
curately against one another in the frame
and thread.
The long inlets do not have to be moved.
5. Then fix both wheel plates again, each
with three M6 fixing screws and tighten
these slightly (2 Nm).
6. With long inlets in the frame, now you can
remove the additional fixing screws again
(see step 2).
If you have short inlets in the frame, now
you can remove the long M6 screws from
the threads of the inlets and reinsert the
tube plugs a the ends of the frame.
7. Position the aluminium locking nuts back
on the drive wheel bushings so that they
rest slightly against the position gates and
then set the drive wheel track correctly
(see Chapter 21.2).
8. Then tighten the three M6 fixing screws on
each of the wheel plates to 10 Nm.
17.3.3 General instructions
After each change to the tipping point:
the wheel track of the drive wheels must
be checked and readjusted if necessary
(see Chapter 21.2).
the caster wheel axles must be readjusted
(see Chapter22.4).
the brakes must be readjusted (see Chap-
ter 25).
Extreme settings such as drive wheels
mounted far to the front are only permitted for
experienced wheelchair users who are able to
actively shift their weight forwards during oper-
ation.
To minimise the risk of tipping backwards,
we recommend using anti-tipping supports,
even with anti-tipping settings.
18 Back system
Avoid falling into the seating and backrest
upholstery/back shell as it significantly in-
creases the risk of an adjustment, falling down
or defects.
18.1 Backrest angle
18.1.1 Adjustment options with backrests
firmly bolted to side sections
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
With backrests bolted firmly to the side sec-
tions, there are no options for flexible backrest
angle adjustment without tools.
However, permanent adjustment of the
backrest 5° forwards or backwards is possible
using tools. To do this, there are three holes in
the rear area of the side section at the top and
an elongated hole at the bottom to position the
backrest tubes. To adjust the backrest 5° for-
