In order to change the position of the wedge adapter:
• (1) loosen all four screws (A),
• push the wedge in the wanted position
• and retighten all four screws (A).
ATTENTION
AFTER EVERY CHANGE MADE ON THE SEAT AND/OR THE
TILTING, THE TILT BEHAVIOR OF THE LOOP MUST BE NEW-
LY TESTED AND PRACTICED WITH A PASSENGER AND THE
HELP OF AN EXPERIENCED AND STRONG PERSON.
2.3.5 Release lever- seat wedge
(2) The red release lever (A) of the wedge adapter should
stick out of the seat plate about 1 cm.
To change the position:
• (2) loosen both screws (B),
• guide the release lever in the wanted position and
• retighten the screws (B).
� INDICATION
With certain tilt adjustments “collisions” between gas
spring and release lever can occur. In this case, be sure
that the gas spring has enough room when the max. tilt
angle is in use; see chapter 2.3.1 tilting.
2.3.6 Position push bar
If, for example, you have a great structure depth of the seat
shell on the back, the structure depth can be compensated
through the position of the push handles.
For this:
• (3) loosen the four screws (A) of the push bar
adapter (B),
• push the ends of the pipes from the push bar in
the wanted position, forward or backward
• and retighten all four screws (A).
ATTENTION
AFTER, IT IS IMPORTANT THAT YOU CHECK THE TILT BE-
HAVIOR OF THE LOOP WITH FULL STRAIN (WITH A PAS-
SANGER) AND THE HELP OF AN EXPERIENCED AND
STRONG PERSON.
IF NECESSARY, THE CENTRE OF GRAVITY MUST BE
CHANGED (WHEELBASE EXTENSION) AND THE POSITION
OF THE ANTI-TIPPER MUST BE RENEWED.
ATTENTION
Regularly check if the spring buttons (C), at the end of the
push bar pipes, functions properly

by screwing it on with the three screws (B) under-
neath the seat plate in the prepared holes.
Step 7: mounting the new gas spring on the top
• (1) Screw the gas spring on to the top adapter (A)
with the screw (C).
Step 8: mounting the new gas spring on the bottom
• (2) Both alternative mounting possibilities of the
gas spring are also shown in picture 2.
• Screw the gas spring in the bottom adapter with
the screw (A) in the prepared holes (B).
INFORMATION
Both gas springs must be mounted in the same mounting
points of the adapter.
INFORMATION
Use the same mounting point as before. Otherwise you
will receive a different tilt direction. For comparison: see
chapter 2.3.1 tilting.

• push the push bar up or down in the guide slots (B)
until the alternative hole (C) is visible.
• There, place the star knob screws (A) in and tight-
en them.
2.4.2 Setting back angle
If you have a seat shell with a xed back angle you can ad-
just the back angle of the Loop to it as follows:
• (2) place the seat shell with the wedge on the
wedge adapter and be sure that the shell snaps
in tightly.
• Remove both screws (A),
• bring the back of the Loop and the back of the seat
shell in a parallel position,
• xate this position by placing both screws (A) in the
alternative holes (B) and
• retighten the screws (A).
2.4.3 Adjustment of back guide
(3) To add the back guide:
• place the clamping part (A) including the connec-
tion part (B) on the traverse (C) of the back pipes,
• place the back pipes of the Loop as close as need-
ed to the back of the seat shell.
To change the distance between shell and back you have
three options:
1. Displace the back of the Loop (see chapter 2.3.6
position push bar),
ATTENTION TILT STABILITY
2. displace the wedge adapter (see chapter 2.3.4 po
sition wedge adapter),
