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.

Version since 02/2017
The wheelchair is delivered with the appropriate toe-in, depending on the wheel camber adjust-
ment and attachment of the steering and pushing aid. When changing the camber or retrotting
the steering or pushing aid, it may be necessary that the toe must be changed.
(1) In order to avoid the so-called "eraser
eect", we generally assemble the matching
track compensation (A) at the factory. If the
camber is subsequently changed, it may be
necessary to replace the track compensation
adapter (A) with a suitable one (spare part).
To change toe-in:
• Remove drive wheels,
• and remove screw connection (B+C).
•
• Depending on the mounting variant
and camber, please observe the instruc-
tions on the following pages.
• After changing the toe settings:
• replace the screws (B+C) and tighten the screws (B).
• Check / correct the distance between the drive wheel and the side part or clothing pro-
tection by attaching the drive wheel.

Safety nuts may only be used once. Once loosened safety nuts must be replaced by new
ones.
An incorrect steering head inclination leads to cornering through the castor wheels to
disturbing and obstructive "ascent and descent".
To replace the caster:
• (2) loosen the screw (A) on both sides,
• remove the steering wheel,
• put the new steering wheel on the slee-
ves.
• Then set the appropriate distances for
the existing steering wheel fork steering
wheel combination

3.2.2 Frame extension
3.2 Assembly Group Frame
When using a standard rm curved back plate,
a new saddleback for the desired width must
be ordered.
To broaden the framework:
• Remove both drive wheels,
• remove the screw connection (3D +
4D) of the seat plate and then the seat
plate itself.
• Now remove the rm curved back plate
(ERGO back: remove the back center
part) by loosening the screws (2A)
• and remove the screwed connections of
the trusses (1A + 4A) on one side.
• Proceed with the use of a back part with
gas spring adjustment, with the traverse
installed there, analog.
• Now pull the frame apart (half desired
broadening)
• and replace the screws loosely.
• Proceed analogously with all screw con-
nections on the opposite side.
• Then tighten the screws again,
• unscrew the seat plate symetrically
• and screw on the new rm curved back
plate (for ERGO back: screw on the cen-
ter of the spine symmetrically).

3.3.1 Horizontal displacement of the seat plate
3.3 Assembly Group Seat
For moving the seat plate by 20 mm / 2 cm
with the same tilting path to increase the seat
depth:
• (1) Remove the screw (D) of the seat
plate completely on both sides.
• (2) Remove the screw connection (F or
D) of the gas spring (E) completely,
• put the seat plate in the alternative
position,
• and tighten the screwed connections
(1D) again.
• Move the gas spring (2E) to the alterna-
tive position (2F or 2D),
• put the screw back in
• and turn it tight.
We recommend a seat inclination of 3-5 °.
After any change to the seat unit and /
or tipping, the tipping behavior of the Loop-
SORGRS must be retested and practiced with
the help of an experienced, strong helper.
If the LoopSORGRS is equipped with two gas
pressure springs, proceed analogously.

3.3.2 Vertical displacement of the seat plate
In addition to the ability to dene the seat
height by the positioning and size of the drive
and steering wheels, this can also be changed
by vertical displacement of the seat plate.
To change the seat height in 20 mm incre-
ments with the same tilting path:
• (1) loosen both screws (C) of the guide
clamp on both sides and
• remove both screws of the screw con-
nection (A) of the seat unit incl. the
calipers (B) on both sides completely.
• (2) Remove the screw connection of the
gas spring (F) incl. The sleeves comple-
tely.
• (2) Move the seat unit with the supports
(D) to the desired dimension in the hole
pattern (E) (± 20 mm / 2 cm per hole),
• (2) move the gas spring in the hole
pattern (G) (± 20 mm / 2 cm per hole)
to the same extent.
• Insert the screws (1A) with the calipers
(1B) into the new position and turn
them tight.
• Insert the screw (2F) with the sleeves
into the connection of the gas spring
and turn it tight.
After any change to the seat unit and /
or tipping, the tipping behavior of the Loop-
SORGRS must be retested and practiced with
the help of an experienced, strong helper.
If you do not move the seat assembly
in parallel with the gas spring, the result is a
dierent tilt path and a dierent seat angle.
