6.3 Adjusting the folding mechanism

Allen key (3 mm) / Wrench (16 mm) / Feeler gauge (0,2 mm)

■■□

1.

Remove the end-stop nut

C

from bolt

E

.

2.

Apply new thread locking adhesive on bolt

E

.

3.

Screw the end-stop nut completely on the bolt again,
but do not tighten.

4.

Adjust the end stop

F

of the folding unit by tightening

resp. loosening the grub screw

D

.

IMPORTANT!

The main purpose of the end-stops is to avoid any
torsion movement of the folding mechanism while
driving the wheelchair on uneven terrain.

– Make sure that the end stops do not have any contact

to the folding mechanism (positions A and B).

– Make sure that the upper and lower edges (positions

A and B) of the end-stops have a distance of 0.2 mm
to the folding mechanism (check with feeler gauge).

IMPORTANT!

The end-stops can turn around their own axis once they
are loose.

– Make sure that the end-stops are completely

horizontal when retightening the end-stop nut.

5.

Tighten the end-stop nut.

6.

Carry out the same settings on both sides.

7.

Check that the scissor mechanism opens and closes
easily.

A noticeable resistance just before the chair is
unfolded completely is normal and even desired
to improve the rigidity of the frame.

8.

Check the seat cover for sufficient tension in unfolded
condition of the wheelchair.

9.

If necessary, repeat the steps above until all settings
are correct.

C

= 13 Nm (high-strength)
