2.5 General safety instructions
Before each use be sure to check:
• frame, back tubes, attachments and accessories for visible damage, bends, cracks or mis-
sing/loose scews,
• wheels/quick release axles for rm t,
• sucient tire pressure, tire tread,
• functionality of the brakes,
• rm t of the angle adjustment elements/ eccentric clamps,
• rm t of the seat plate/ the back/ the foot plate,
• functionality of the anti-tipper/ seat and back straps,
• if all previously disassembled parts are re-inserted or rmly locked.
There is a risk of injuries (e. g. such as bruising) on all rotating or folding parts, including
adjustments, repairs and transport.
All wheelchair parts are to be handled with care. Do not throw or drop removable parts.
Before repairs or adjustments are made, clean/didinfect the wheelchair and secure it from
tipping over and/or falling down.
Only use original spare parts.
Safety nuts may only be used once. Lossened safety nuts must be replaced by new ones.
Only the regular maintenance of all safety-relevant parts on the wheelchair by a qualied
rehab workshop protects against damage and maintains our manufacturer's warranty.
Combination with products from other manufacturers
The wheelchair may only be combined with the electrical auxiliary drives apporved by the
manufacturer. Restrictions or adaptations as well as the attachment itself must be done by the
supplier of the additional system or the authorized specialist dealer.
Please check the conditions with the manufacturerer of the audiliary drives.
In combination of wheelchair and electric auxiliary drive, certain strains can occur which
can lead to damage to the wheelchair. Slowly approach obstacles and carefully overcome
them so that little force is applied to the caster, driving wheel and wheelchair as a whole.

3.1.1 Position rear wheel
3.1 Assembly Group Wheels
Check the tilt stability of Loop while fully tilted and with the patient, after alle positioning
adjustments of the rear wheels have been made and, if necessary, modify the position.
(1)We mount:
• 24” wheels in row (A),
• 22” wheels in row (B),
• 20” wheels in row (C),
• the adapters for 12”/16” wheels are
mounted in row (D).
Position 1 is the most passive (most stable), po-
sition 5 is the most active (most wobbly). The
wheels are factory-set in position 2. In this po-
sition, you receive a horizontal frame position
with corresponding caster. Other constellations
are possible. The horizontal frame position can
be reached through the adjustment of the cast-
ers.

3.3.1 Adjusting the tilting direction
3.3 Assembly Group Seat
(1) The tilting direction is determined by the
position of the gas spring at the bottom of the
carrier (A) and on top on the holders under
the seat board (B) as well as by the horizontal
(C) and vertical (D) position of the seat.
We mount standardly as follows:
For tilting from -5° to +35°:
• (2) with frame size 1 and 2,
• (3) with frame size 3.
For tilting from +2,5° to +40°:
• (4) with frame size 1 and 2,
• (5) with frame size 3.
After every change made on the seat
and/ or the tilting, the tilt behaviour of the
Loop must be newly tested and practised
with a passenger and the help of an experi-
enced and strong person.

3.3.2 Displacing the seat plate horizontally
3.3 Assembly Group Seat
In order to displace the seat plate by 2 cm with
the same tilting direction (only possible with
frame sizes 2 and 3):
• (1) remove the screws (A) from the seat
plate (B) on both sides including the in-
ner shells completely.
• (2) Remove the screws (F and D) from
the gas spring (E) completely,
• move the seat plate (1B) to the alterna-
tive position,

• replace the screws (1A) through the shell
• and retighten the screw connections
(1A).
• Place the gas spring (2E) in the alterna-
tive position (2F and 2D),
• replace the screw
• and tighten it.
After every change made on the seat
and/ or the tilting, the tilt behaviour of the
loop must be newly tested and practised
with a passenger and the help of an experi-
enced and strong person.

In order to displace the seat plate by 2 cm with
the same tilting direction:
• (3) loosen both screws (C) from the
guide clip on both sides and
• remove both screws from the screw con-
nection (A) of the seat unit including the
half shells (B) on both sides completely.
• (4) Remove the screw connections of the
gas spring (F) including the shells com-
pletely.
• (3) Move the seat unit with the carriers
(D) to the desired measurements in the
holes (E) (each hole is ± 2 cm),
• (4) Displace the gas spring in the holes
(G) (each hole is ± 2 cm) in the same
measurement.
• Place the screws (3A) with the half shells
(3B) in the new position and tighten
them rmly.
• Place the screws (4F) with the shells in
the connection of the gas spring and
tighten them rmly.
After every change made on the seat
and/or the tilting, the tilt behaviour of the
loop must be newly tested and practised
with a passanger and the help of an experi-
enced and strong person.
If you do not displace the seat unit and
the gas spring parallel, a dierent tilting
direction and a dierent seat adjustment will
result.

In order to change the position of the wedge
adapter:
• (3) loosen all four screws (A),
• push the wedge in the wanted position
• and retighten all four screws (A).
After every change made on the seat

3.3.5 Release lever-seat wedge
3.3 Assembly Group Seat
(1) 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 po-
sition and
• retighten the screws (B).
With certain tilt adjustments “collisions” be-
tween 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 tilting

~ 1 cm
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:
• (2) 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).
After, it is important that you check the
tilt behaviour of the loop with full strain
(with a passanger) and the help of an experi-
enced and strong person.
If necessary, the centre of gravity must be
changed (wheelbase extension) and the po-
siton of the anti-tipper must be renewed.
