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.

• With the screws (A1-4) remove the ax-
le plate (B) incl. all angle parts and half
shells (C) on one side first.
• The crossbar adapter (D) is attached
with the screw (A1) at delivery. When

• (1) Screw the crossbar adapter (D) with
the new screw to the frame tube.
• Proceed the same on the opposite side.
• The axle plate can be turned vertically
180° in order to reach a higher position.
For this, proceed in the same manner.
After every change on the driving wheels the effectiveness of the knee lever brake must be
checked and, if necessary, newly adjusted.

piece (B).
• Proceed accordingly on the opposite si-
de.
• Make sure that both quick release axle
fittings are positioned the same on both
sides.
• Replace the driving wheels and be sure
that the driving wheels have the same
distance to the side guards on both si-
des.
(2) The driving wheels must have a
distance of 10 mm at the top from the side
guards. If necessary, you must correct the po-
sition by turning the quick release axle fitting
in or out.
After every change on the driving
wheels the effectiveness of the knee lever
brake must be checked and, if necessary,
newly adjusted.

After every change on the driving wheels
the effectiveness of the knee lever brake
must be checked and, if necessary, newly
adjusted.
3.1 Assembly Group Wheels
(1) The camber is set with dierent camber
parts (spare part). Picture (1) shows:
• half shell (A)
• camber wedge (B)
• axle plate (C)
• quick-release axle fitting (D)
• drum brake hub (E)
(1) In order to change the camber remove the

• Remove the axle plate (C) as describrd
in the previous chapter. The drum brake
hub (E) with the quick release axle fit-
ting (D) do not need to be removed.
• Replace all camber wedges (B) with the
new ones.
Please note that you remove the back crossbar
incl. the crossbar adapter with the screw in the
bottom back. (see previous chapter).
(1+2) Applying the new camber wedges:
• Place the four screws (F) in the approp-
riate holes of the axle plate,
• after, „thread“ the new camber wedges
(B) on the screws (F).
Please note that the camber wedges are not
symmetrical and that they have a ‚‚front“ and a
„back“.
• „Thread“ the half shells
(A) on the screws
(F)
• and tighten them on the appropriate
position on the frame.
• Check the distance from driving wheel
to side guard(see previous chapter).
(3) If necessary, correct the quick release axle
fitting and turn it as far in or out so that the ti-
re of the wheel has as little distance as possible,
however atleast 10 mm from the side guard or
the skirt guard.
• Loosen the nuts (A),
• turn the quick release axle fitting (B) in
or out and

3.1.4 Casters
The caster adapters are attached to the frame
tube with two screws each. The (in driving di-
rection) front one goes in a thread in the frame
tube, the back one (3A) through the adapter
and the eccentric plate (3C).
(1+2) To displace the caster adapters (A):
• secure the wheelchair from rolling away.
• Remove the protective cap (B) on both
sides of the wheelchair.
• (2) Remove both screw connections (A)
on both sides.
• Move the screws (A) in the new holes
(B).
• Then put on (if available) the spacers (C)
from the outside
• and then the adapter (D) on the screws
(A)
• and retighten them.
• Proceed in the same manner on the op-
posite side.
The caster adapter must be aligned to the floor
at an angle of 90°. Otherwise the follow-up of
the fork creates wave like movements in curves.
(3) To adjust the caster adapters:
• Place the wheelchair on even ground.
• From the front, place a right angle to the
adapter.
• Loosen both nuts (A+B).
• With a screw driver turn the eccentric
plate (C) in the slot in the appropriate
direction until the adapter is in an exact
90° angle.
• Retighten both nuts (A+B).
(4) To displace/replace the casters:
• Remove the screw connections (A) of
the axle completely,
• remove the husks,
• replace the casters,
• guide the husks and wheels, if necessa-
ry, in the desired holes (B),
• replace the safety nuts with new ones (!)
• and retighten all screws.
Be sure to check that after moving the casters,
the caster adapter is still at a right angle. If ne-
cessary, you must adjust the caster adapter as
stated above.

3.5 Assembly group leg support
3.5.1 Standard leg support
The mounting of the leg support takes place in
the middle under the seat plate.
Setting the lower leg length (vertical adjust-
ment):
To set the lower lege length you have several
possibilities:
• (1) Loosen the clamp lever (A),
• place the whole foot plate holder (B) in
the desired position,
• tighten the clamp lever (A).
(2) You gain additional length:
• 1.) by moving the clamp bracket (A) in
alternate holes (B).
• Loosen the clamp lever (C) far enough
so that you can move the clamp bra-
cket (A) along the drill pattern (B) to the
desired position.
• After, tighten the clamp lever (C).
• 2.) by moving the complete foot plate
holder (D) in alternate holes (E).
• Remove the screws (F),
• move the foot plate holder (D) in the al-
ternate holes (E)
• and screw the foot plate holder (D)
tightly in the new position.
When moving the seat plate forward, the
leg support stays in its original position. For
balance correct the horizontal distance of the
leg support as described below.
Setting the depth (horizontal adjustment) with
a centre mounted leg support:
• (1) Loosen the clamp lever (C),
• place the whole leg support (D) in the
desired position,
• retighten the clamp lever (C).
Setting the depth (horizontal adjustment) with
dual mounted leg support/s:
(3) The leg supports are connected to the seat
plate with both holders (A) (here shown trans-
parent) by the screws (B).

3.5 Assembly group leg support
3.5.2 Foot plate: can be elevated, continuos/ divided
(1) To elevate the leg support:
• Secure the wheelchair from rolling away
by tightening the wheel lock and acti-
vating the anti-tipper.
• Loosen (if necessary on both sides) the
latch (A) with the rings (B),
• lift the leg support/s (C) in the desired
position and
• release the latch/es (A).
• The latch must lock tightly!
(2) To balance the length proceed as described
in the previous chapter or:
• Loosen (if necessary on both sides) the
clamp lever (B),
• pull the bottom end (C) of the leg
support/s to the wanted length
• and retighten the clamp lever/s (B).
(2) Very short lower leg length
For very short lower leg lengths you can saw
off the bottom (C) or the top square tube (D).
(2) Very long lower leg length
For very long lower leg lengths you can move
the holder (E) of the clamp lever (B) down and
pull the square tube out to the wanted length.
Before fixating the foot plate/s in the
new position be sure that the casters can still
turn 360° under the foot plate with a hori-
zontal seat position without any problems. If
necessary correct the lower leg length with
the seat height.
