2.1 Material information
The base frame and the individual elements are made of aluminium which
is non-corroding and powder-coated.
2.2 Handling / transport
The seat pan sub-frame is not intended for carrying, since it is equipped
with castors. Should you have to carry the equipment due to obstacles,
ensure that all moving parts are tightened. To transport the sub-fra-
me, reduce all adjustments to their most compact size (fold up push bar,
adjustbackangleetc.).Tothisend,pleasepayattentiontoPoint2.10.ofthese
instructions for use!
2.3 Application areas, use according to the intended purpose
The oyd. seat pan sub-frame is a medical product of risk class 1 and
designed to accommodate seat pan systems and seat pans for larger
users with higher weight or a higher degree of activity. The load incl. seat
pan should not exceed 120 kg and any type of seat pan can be adapted
without any problems. oyd. is suited exclusively for use with an accom-
panying person.
2.3.1 Indication
Seating aids are used to compensate a disability with moderate to heavy
incorrect sitting postures and/or sitting instabilities. The underlying dama-
ge as cause of the impaired sitting varies. Often the interplay between
pelvis and spine is disturbed due to congenital or acquired damage to the
torso (bony or joint structures) or due to congenital or acquired functional
impairments of the motor system (muscular, neuronal, cerebral, due to in-
jury). Examples for clinical pictures/illnesses could be: cerebral movement
disorder, myelodysplasia, muscular dystrophy or atrophy, multiple sclerosis,
stiening of hip or knee joint.
2.3.2 Contraindications
In general, the indications for a seating aid should be approved by a doc-
tor or orthopaedist. It should therefore be clarified prior to procurement
whether contraindications exist for the patient.
In general, any type of pain represents a contraindication.

2.8 General settings
To correctly us the oyd. seat pan sub-frame, it must be adjusted
correctly. Some important points are as follows:
• With the seat angled more, the rear wheels should be moved back –
and moved forwards with a slight tilt.
• The axle of the rear wheels are positioned vertically under the hip joint
for persons driving themselves.
2.9 Utilisation training
Make your first trial run on even ground without occupants until you have a
feeling for the oyd. seat pan sub-frame. You must take extra care when
driving hills and slopes or when overcoming obstacles.
Use the tip protectors for initial uses (optional).
2.10 Climbing stairs
Stairs may only be attempted with a minimum of 2 accompanying persons.
The helpers may only hold on the the frame and firmly mounted frame
parts without lifting oyd. (to carry)!
When driving up stairs, the helper at the back holds the chassis on the
fixed handles and pulls over the steps and the helper at the bottom holds
the front frame tubes and stabilises the position. They also press the chas-
sis into the steps parallel to the floor.
Carry the seat pan sub-frame only in emergencies - risk of accidents!
When lowering, the bottom helper brakes by pressing the chassis in stages.
The top helper provides counterpressure on the push bars and holds the
chassis in the right position. The chassis must be rolled down step by step.
Please check whether the groups on the back tubes are locked in place!
Bags and objects must be removed from the backrest to avoid hindering the ac-
companying person.

Settings and adjustments to the product or accessories may only be made
by people who have been given the necessary instructions by a medical
product advisor. Please ensure that none of the user's extremities are in
the respective area when making adjustments of any kind to minimise the
risk of injury.
3.1 Seat tilt
The seat of the oyd. can be ad-
justed by 30° in the basic setting
using gas pressure springs. You must
press the trigger lever (A) on the right
side on the push bar or push handle
or assist by lightly pulling or pus-
hing. Once the required seat angle
has been achieved, the gas pressure
spring is blocked again by releasing
the trigger lever.
There is an increased risk of tipping
over with a tilted seat! We therefore
recommend using the optional anti-tip
mechanism.
3.2 Back angle adjustment with snap joint
The back frame can be precisely ad-
justed in the angle to the seat frame.
The adjustment is made after loo-
sening the two star handles (B) on the
right and left at the lower end of the
back frame. Always hold the back with
one hand when adjusting. The back
can also be fully folded down onto the
seat frame for easier transport.
There is an increased risk of tipping over
when adjusting the back more than 90° to
the seat frame!

3.3 Back angle adjustment with central quick adjustment
The back can be adjusted via the central fast adjustment at an angle of
90° to 120° to the seat frame. For versions with a gas pressure spring, the
adjustment is made by pressing the lever on the gas pressure spring (A)
and by releasing the clamp lever (B) for the mechanical version.
The back can be folded down onto the seat
frame for easier transport. Press the button
on the quick release axle on the lower end of
the centralised fast mechanical adjustment
and take out the quick release axle. When
folding back, place the fast mechanical ad-
justment in the adapter and reattach the
quick release axle.
Check the tight axial t of the quick release axle
for each assembly!

3.4 Seat height adjustment
The height of the seat adapter can be
adjusted by loosening both screws (A)
on the horizontal tubes.
Max. height adjustment 8 cm!
The height of the gas pressure spring
or the two gas pressure springs for
versions with double gas pressure
springs must then be adjusted. Loo-
sen the screw connections (B) for this
and aligned to the corresponding hole
distance (in the same way as the ho-
rizontal tubes have been adjusted).
Tighten the screw connections again
after all adjustments.
The setting may only may made with the
seat unoccupied.
3.5 Seat depth adjustment
The depth of the base plate for moun-
ting the adapter including the seat
pan can be adjusted by loosening the
4 screws (C).

3.6 Back unit adjustment
The complete back unit can be adjus-
ted in the depth of the seat pan / seat
unit. Remove the 4 screws (arrows) on
the right and left of the top frame, sli-
de the back unit out or in and insert
the screws again and tighten.
3.7 Push handles
The push handles of the oyd. can
be adjusted individually in height. This
takes place after loosening the two
clamp levers (A) on the rear tubes. The
clamp lever must be tightened again
after each adjustment.
3.8 Push bar
The design with the push bar is a more
comfortable solution. The angle of the
push bar can be individually adjusted
in addition to height adjustment using
the joints with quick release (B). The
height is adjusted after loosening the
two clamp levers (C) on the rear tubes.
The clamp lever and quick release
must be tightened again after each
adjustment.

The following are general rules:
High air pressure: Low rolling resistance / less suspension comfort
Lower air pressure: Higher rolling resistance / more suspension comfort
See point 9 for sizes and air pressure for the guide and rear wheels (techni-
cal data).
4.1 Rear wheels with drum brake
The drum brake allows safe braking, which is independent of the tyre pres-
sure. It is activated with the brake lever on the right and left push handle
with four engagement options. A safety catch engages with an audible
"click" by pulling the lever. The brake is applied in the fourth click position.
Release the brake by pulling the lever again and pressing the red safety
catch at the same time. By braking lightly on one side it is possible to
achieve a steering movement when pushing.
Setting the drum brakes
The drum brakes are set by turning the
setting screws (A) in or out. They are
located at the lower end of the bra-
ke cable in the brake saddle. Unscrew
the screw a little for precise adjust-
ment until you hear a grinding noise
with turning the rear wheel. The bra-
ke jaws are placed lightly against the
hub housing in this state. Then turn the
setting screw 1 turn back and clamp it
in place with the nut. Check the function of the drum brake and readjust
the setting screw if necessary.
Leave this work to your specialist dealer in case of any uncertainty.
The drum brake may only be used on the level with maximum load as a
parking brake due to safety reasons. The knee lever brake must always be
used on a slope and tilt up to a maximum of 8%.

4.2 Quick release axle
The quick-release axles of the rear
wheels make transporting your oyd.
significantly easier. You only need to
press the button (A) in the centre of
the wheel hub, and the wheel can be
easily removed or reinserted. When
inserting the quick release axles, you
should be able to hear it engage with
an audible "click".
Check the tight axial t of the quick release axle each time the rear wheel is
mounted!
4.3 Wheelbase
If the rear wheels are mounted far
back (B), you have a large distance
between wheels and therefore good
stability, or a safe position with res-
pect to the danger of tipping over.
However, manoeuvrability is lost. If the
rear wheels are mounted further to the
front (C), the oyd. is very manoeuv-
rable due to the shorter wheel distan-
ce. However, please note that there is
a big risk of tipping over in this positi-
on. This particularly applies if the seat
surface is adjusted backwards (see
Point 3.5). Therefore always use the
swing-away anti-tip mechanism due
to safety reasons (see Point 5.2).
To adjust the wheel distance, please
remove first the rear wheels (see Point
4.2) and then remove the brake anchor
and the clothing guard (if available).
Now loosen the screws (D) and bring
the perforated plate (E) into the requi-
red position.
After each adjustment, please re-tighten all screw
connections!

4.4 Guide wheels
To guarantee perfect steering control, the
steering axle on the front wheels (A) must be
positioned vertical to the surface (B). If this no
longer the case due to changes to the rear or
front wheels, the front wheels can be read-
justed by turning the two eccentric nuts (C)
on the front wheel adapters. It is recommen-
ded to use an angle bracket or similar. After
each adjustment, please retighten all screw
connections and make sure that both sides
are adjusted equally!
After each adjustment, please re-tighten all
screw connections!

5.1 Tilting device
Using the tilting device, the accompanying
person can tilt the chassis easier, e.g. to drive
over a kerb.
The tilting device is mounted in the rear, lower
frame tube.
5.2 Swing-away anti-tip mechanism
The swing-away anti-tip mechanism
prevents the chassis from tipping
back.
Note: When driving over steps or
curbs, the anti-tip mechanism (A)
must be swung in 180° to the front to
avoid touching the ground. Briefly
press the bar (B) down and then turn
180° inwards (C) - the bar automati-
cally clicks into place again with the
spring. Swinging back takes place in
the same way.
5.3 Knee lever brake
The knee lever brake serves as a par-
king brake. Check that the brakes are
in perfect working order and check
the air pressure in the rear wheels be-
fore each use. The brake is applied in
the direction of travel by swinging the
brake lever. The correct distance bet-
ween the tyres and brake is important
for the correct function of the brake. It
should be approx. 2 cm with the brake
released. This size can vary somewhat
depending on the tyre pressured or
the type of tyre used.
Guide: The tyres should always be
pressed in lightly by the applied brake. It is possible to adjust the brake by
release the two Allen screws on the clamping block (D). Firmly tighten the
screws again.

5.4 Footrests
There are dierent footrest variants for oyd.,
which are fixed to the seat frame at the
base plate for external adapters. After in-
serting the knee angle in the footboard ad-
apters (A) under the base plate and setting
the depth, the footrest is tightened with the
two wing screws (B). The knee angle can be
adjusted and the lower leg length indivi-
dually adapted. Foot benches can be fol-
ded up and the angle adjusted depending
on the variant. Tighten the corresponding
screw connections after all adjustments.
After each adjustment, please re-tighten all
screw connections!
5.5 Clothing guard, removable
Alongside the fixed clothing guard, the clo-
thing guard can also be supplied as a re-
movable guard to achieve a more compact
transport size. This is done by loosening the
two knurled screws (C).
Pay attention to a tight t when mounting the
clothing guard!

6.3 Seat plate assembly
Transfer the hole pattern of the trape-
zoidal adapter onto the seal pan body
and mount the seat plate with four M6
countersunk screws (strength class
8.8) onto the trapezoidal adapter.
Please use M6 self-locking nuts (min.
strength class 8) to fasten. If using
push-in nuts in the seat place, plea-
se secure the screws (e.g. with Loctite)
against becoming loose due to
vibrations and impacts!
When assembling a seat pan make sure that the seat pan body (back and seat
plate) is made of a minimum of 3 mm aluminium sheet. Also make sure that no
sharp edges remain on the pan body.
