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 Centre of gravity
(1)To set the centre of gravity
• remove both rear wheels,
• remove all screws (A)
• displace the perforated plate in the alter-
native holes (B).
• Displacement must occur parallel on
both sides.
• Replace screws and tighten them.
After every change made on the rear
wheels, the wheel lock must be newly adjust-
ed.
Slowly go to the maximum and from the
user (!) wanted point of wobbliness.
The more you move the casters back, the higher the risk that the wheelchair will tip forward
when getting in or out.
The more you move the rear wheels with the perforated plate forward, the higher the risk that the
wheelchair could tip backward.
Please make sure, that with the seat slant the grip point and grip direction are not aected by a
too high placement of the rear wheels.
3.1.2 Seat height in front
(2) The seat height is set by the position of the
casters in the caster fork.
• remove the connection caster/caster
fork (A) completely,
• mount the casters on both sides in the
wanted holes (B),
• retighten all screws.
After every change you must check the vertical
steering head slant and, if necessary correct it
(see chapter steering head slant).
In the mounting parts of the casters, hair,
lint, dirt, etc. can collect, whereby the casters
become hard to use. Remove the casters in
short intervals and clean the forks, axles and
the husks thoroughly.
Precede the same with synthetic forks.

3.1.3 Seat height in back, seat slant
After each change made on the rear wheels the functionality of the wheel lock must be
checked and the casters must be newly adjusted.
Generally, the seat height in back is about 2-3 cm lower as in front, for a safe and comfortable seat
position with a good distribution of the seat pressure and to avoid a “sliding out”. However, other
settings in individual cases can also be useful.
• (1) Remove the rear wheels,
• remove the side guards/skirt guards with
the screws (A) (easily remove the desk
side guard)
• (2) remove the quick-release axle tting
including all washers in the alternative
holes (C)
• and retighten all screws. (tightening
torque nuts M18 tting 35Nm).
• Mount the side guards and place the rear
wheels back in the quick-release axle.
The ttings must stick out of the perforated plate at the same length on both sides. The ttings
can only stick out so that the side distance of the tires to the side guard is as low as possible,
however a min. of 10mm.
3.1.4 Steering head slant
After every change on the rear wheel, the steer-
ing head slant must be newly adjusted.
To adjust the caster adapter:
• (3) remove all screws (A) on both (!)
sides,
• remove both screws (B).
• By tuning the adjust washer (C) (with a
at head screw driver) place the adapter
in a vertical position (using an angle).
• Retighten all screws; screws (A) with 9
Nm, screw (B) with 7 Nm.
A falsely set steering head slant can lead to the casters shaking back and forth and can lead to
hindering curve rides (from casters).

native holes (C).

3.1.5 Replacing/ displacing the caster adapters and casters
Through the camber you inuence:
• the side tilt stability,
• the shoulder rear wheel position and
• the track width of the wheelchair.
(2) To avoid the so called “eraser eect” we gen-
erally mount the tting track balance ex-works
(A). With a change of the camber afterwards,
the track balance adapter (A) must be replaced
by one that ts (spare part).
With a camber of 8° a distance block to the
wheelbase extension is necessary (spare part).
Adjusting the camber
• (3) Remove the rear wheels,
• remove screws (A) and move them in
the alternative holes (B),
• retighten the screws.
For a camber of 8°:
• (3+1 next page) remove the screws (A),
• remove the screws (C),
• move the perforated plate holder (D) by
turning it 180° on the outer part of the
frame tube,
• replace the screws (C) and tighten them,
• replace the perforated plate with the
screws (A) and tighten them.
The setting may not be possible if you wish to
widen the seat, being that then you would have
to turn the quick-release axle ttings too far out
of the perforated plate.
Check/correct the distance of the rear wheel to
the side guard and skirt guard by attaching the
rear wheel.

The tire of the wheel must be at least 10 mm
away from the side guard/skirt guard. Take no-
tice that the distance on the left and right are
the same!
(1) In order to screw on or screw o the
quick-release axle ttings:
• remove the screws of the ttings (B)
(the lock nut (2E) on the inner surface
as well),
• turn the whole tting (C) in the wanted
position and
• retighten the screws (tightening torque
nuts M18 tting 35 Nm).
You must check the functionality of the
knee lever brake and if necessary reset them.
3.1.7 Rear wheel track balance
Version till 02/2017
If you have to change the camber and/or the seat slant you must, in order to avoid the so called
“eraser eect”, mount appropriate wedge plates for the track balance.
To change/set the wedge plate;
• (1) remove the screws (A) of the quick-re-
lease axle ttings (D) (also on the inside),
• apply the needed wedge plate/s (B),
• the mounting grooves (C) must point
forward in driving direction,
• replace all other washers
• and retighten the screws (A) of the
quick-release axle ttings (D) (also on
the inside)
(turning point 35 Nm).

• loosen the screw connection (B) of the
tting (also the lock nut (2E) on the

• Turn the complete tting (C) to the
desired position and
• Tighten all screw connections again
(tightening torque of nuts M18 tting

Please note the colored discs for the correct
adjustment of the camber.

Version from 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 rear 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 rear wheel and the side part or clothing protec-
tion by attaching the rear wheel.

parallel to the outline of the rear wheel.
High settings can become hazardous for active
drivers.
