5 Introduction
Before starting your first journey, familiarise
yourself with these usage instructions, paying
particular attention to all of the safety infor-
mation and hazard warnings contained in
them.
Allow your therapists and doctors to advise you
as well as your carers and assistants on how
to use the product and what you are permitted
to do with the product based on your current
ability. Clarify with them as well which wheel-
chair techniques you can learn on the basis of
your ability.
Under no circumstances should you do
anything with or in the product that you have
not learned to do and have not mastered.
You, your carers, and assistants should also
seek advice from your therapists and doctors
as well as the rehabilitation specialist dealer
about the use and settings of your product and
all the safety accessories available (e.g., anti-
tipping supports and lap belt).
You should always heed the advice pro-
vided by doctors, therapists and the rehabilita-
tion specialist dealer on the necessary safety
accessories.
If you are not sure how to handle the
product or if technical faults occur, please con-
tact your rehabilitation specialist dealer or
PRO ACTIV before using it.
Never leave the product unattended.
Secure the product against unauthorised
use and theft.
When combining your product with
equipment made by other manufacturers (e.g.
seat cushions, drive devices, etc.), make sure
that the suitability of the individual components
and the unit made up of them is ensured. In-
formation on the suitability of the combination
can be obtained from the manufacturer of the
third-party components or from your rehabilita-
tion specialist retailer.
The product contains small parts that may
pose a choking hazard for children.
6 Intended purpose and indication
This product offers persons who have difficulty
walking or cannot walk the option of replacing
walking with driving using a muscle-powered
wheelchair to a technically feasible extent. The
objective is to maintain or increase the greatest
possible independent mobility and to integrate
the active wheelchair user in everyday life.
Indications: Walking impediment or limited
ability to walk due to paralysis, limb loss, limb
defect/deformation, joint contractions/joint
damage, neurological and muscular diseases.
Contraindications: Some wheelchair options
are unsuitable for certain disease profiles or

LIFT activ & solid usage instructions
7
handicaps. A suitable selection will be made by
the therapist/doctor/rehabilitation specialist
dealer during the consultation.
In addition - for safety reasons - the product
may only be operated by people who
 can move and coordinate their hands and
arms so that they are able to operate all
control elements without restrictions while
using the wheelchair.
 are physically and mentally capable and
have the visual ability to safely operate the
product in all operating situations and can
meet the legal requirements for use on
public roads. For children or people with
mental, significant motor or visual impair-
ments, the attendants can ensure the re-
quired traffic safety as a substitute and as
a companion.
 have been trained in its use by the rehabili-
tation specialist dealer or PRO ACTIV.
7 Proper use
This wheelchair is designed for use on level
and solid surfaces indoors and outdoors. Avoid
driving on unpaved or loose surfaces (e.g. on
loose gravel, in sand, mud, snow, ice or
through deep puddles of water, and under poor
weather conditions (e.g. storms), as this may
result in incalculable risks.
Thanks to the infinitely variable seat height
adjustment, the LIFT activ & solid active
wheelchairs are particularly suited for use at
the workplace or at home with conventional
furniture and kitchen facilities. With the LIFT
activ, a low wheelchair weight and a small
pack size make it easy for active wheelchair
users to load it in a vehicle.
With the LIFT activ, the maximum permitted
load of the product in its standard design is
100 kg. Individual customisation can be made
to accommodate a higher load; this will be
indicated on the ratings plate.
With the LIFT solid, the maximum permitted
load of the product in its standard design is
120 kg. The heavy-duty version and individual
customisations can be designed for a higher
load; this is then indicated on the rating plate.
Please note that the load limit indicated on the
rating plate may not be exceeded even when
transporting objects and carrying out strength
exercises in the product. Note that the maxi-
mum load weight is reduced accordingly when
mounting components with low load limits on
the product, e.g. drive wheels with few spokes.
Proper use of the product is a basic require-
ment of safe operation. The product may gen-
erally be used only for applications that are
listed and described in these usage instruc-
tions. This includes storage, transport, mainte-
nance/inspection, and repair, as well as the
safety information in each chapter of these
usage instructions.

LIFT activ & solid usage instructions
9
field representative or by a product consultant
from PRO ACTIV.
You will be fully instructed in the use of the
product based on the usage instructions in-
cluded in the delivery. You will be handed over
a record of training and handover certificate as
written proof. In addition, you will be handed
the usage instructions and, if necessary, fur-
ther accessories for your own use. It is rec-
ommended that you take along an assistant to

you later when handling the product.
During the hand-over, the record of training
(Chapter 40) and the hand-over certificate
including the associated check list (Chapter
41) must be filled in. The rehabilitation special-
ist dealer should send the completed docu-
ments to PRO ACTIV for filing as a file by e-
mail or in the form of a copy by fax or in the
post.
11 Introduction to the product & the
surroundings
During the initial commissioning of the product,
drive at minimum speed and become accus-
tomed to the driving characteristics of the
product. Always adapt the speed and driving
manoeuvres to match your own abilities and
external circumstances. You will get a feel for
how to use the product safely after a short
time. Before driving up or down slopes or hills
with the product, you should be proficient in the
safe handling of the product on level ground.
Familiarise yourself with the lift function and
the changes in the centre of gravity in a lifted
state. Before you take on additional loads, you
should be comfortable with the lift function.
Practice bending over, gripping, stretching and
getting out, until you know the limits of your
abilities. Allow yourself to be assisted until you
know what can cause falls or tips and how to
avoid it.
Get to know the environment in which you wish
to use the product. Look out for obstacles and
learn how to overcome or avoid them.
12 Safety instructions – prior to
driving/use
When getting into the wheelchair, do not
tread on the footrests as this may tip the chair
over.
Before every trip, check the condition of
the wheels (e.g. visual inspection of the spokes
and rims, check the tyres for damage, foreign
bodies and crack formation). If you have any
doubts about the serviceability of the product,
stop using it.
Check the tyre pressures at regular inter-
vals. Ensure that you comply with the manu-
facturer's specifications which can be found on
the tyres. If the tyre pressure is too low, the
optimum functional capability of the knee lever
brake is not guaranteed, and an excessively
low tyre pressure influences the driving behav-
iour. Apart from that, there is an increased risk
of a flat tyre.
Before starting out, check that the
product's brake works. If all existing brakes are
not fully functional, no trips may be taken.
Check the stable condition of the seat
and backrest upholstery at regular intervals
and in case of doubt, have your rehabilitation
specialist dealer assess its condition.
Always ensure that your feet cannot slip
off the footplate support when using the prod-
uct.
Before using the product, ensure that the
anti-tipping supports are in the operating posi-
tion and are functional.
Due to environmental effects, it is possi-
ble that the properties and therefore secure
attachment of the push handle covers may
change detrimentally. For this reason, it is
important to check that the handles are tightly
fitted and fixed in position prior to use. If this
should no longer be the case, then the push
handles may not be used until they have been
fixed.

LIFT activ & solid usage instructions
10
Before each use of the product, make
sure that the anti-tipping supports and push
handles are firmly attached and the quick-
release axles on the caster and drive wheels
are also securely locked in place.
Depending on equipment, the product
may have folding/closing mechanisms that
pose a risk of crushing injuries (e.g. trapping
your fingers). Therefore, have your rehabilita-
tion specialist dealer explain how these mech-
anisms work and test them yourself under
supervision.
If required, you can have your product
equipped with a suitable chest or lap belt.
Make sure that the belt is worn so that it does
not negatively affect your breathing, cannot
strangle you if you fall or tip out of the product
and so that you can easily remove it yourself.
Make sure that the passive illumination
(reflectors) are always on your product, are in
perfect condition and are clearly visible.
When travelling, always carry a repair kit
and tyre pump for repairs in event of punc-
tured/flat tyre. An alternative to this is an
emergency puncture repair spray that fills your
tyre with a foam that hardens in the tyre.
13 Safety instructions – while driv-
ing/using
Note that some parts of your product can
become extremely hot at high ambient temper-
atures (e.g. sauna). This means that above
50°C, the product may be damaged and above
40°C there is already the risk of burns for the
user, which should not be underestimated,
particularly for people with impaired sensitivity.
For this reason, the product should not be
exposed to such extreme temperatures.
PRO ACTIV cannot accept any liability or pro-
vide any warranty for personal injury and mate-
rial damage caused by such stresses. There
are also certain risks that exist at extremely
low temperatures, which must be minimised by
wearing appropriately insulating clothes, for
example.
You may only drive on slopes where the
product can be safely controlled with the
handrims. Never drive the product on slopes of
more than 10%.
When driving in curves, reduce your
speed to a minimum and if possible, lean your
upper body towards the curve.
Do not ride parallel to slopes and inclina-
tions due to the risk of tipping.
Do not stop on a steep slope, otherwise
there is a risk of losing control of the product. If
possible, do not turn on a slope or change your
direction.
Note that the knee lever brake and the
integrated brake are parking brakes that may
only be applied when the product is at a stand-
still. These are not service brakes that are
suitable for reducing speed.
Do not attach objects (carrier bags, etc.)
to the product.
When driving in areas that are approved
for pedestrians, keep to the maximum permit-
ted speed (walking speed 6 km/h) and main-
tain sufficient lateral distance (at least the
width of a wheelchair) from obstacles and oth-
er road users.
Avoid driving on unpaved or loose sur-
faces (e.g. on loose gravel, in sand, mud,
snow, ice or through deep puddles of water).
When travelling on poorly maintained
paths (e.g. coarse gravel, potholes), there is an
increased risk of puncturing your tyres as well
as tipping.
When travelling on poorly maintained
paths with potholes and loose stones, drive
carefully to prevent the caster wheels from
blocking.

LIFT activ & solid usage instructions
11
The product can affect other devices, for
example theft protection barriers in department
stores.
The product is only intended for transport-
ing one person with limited mobility and must
not be used for any other purpose, e.g. for
transporting goods.
When reversing, the anti-tipping supports
should always be used as there is an in-
creased risk of tipping over. If this is not possi-
ble, then ask other people to help ensure that
there is no risk of tipping over.
The product may only be propelled using
the handrims. If you propel the chair with the
tyres (thumbs or fingers on the tread of the
tyre), there is the risk of crushing or otherwise
injuring fingers and thumbs.
Do not reach into the area of the spokes
or other tight spaces in the area of the wheels.
There is an increased risk of being injured
here, particularly while in motion. If you have
limited coordination of your limbs, then you
should cover the spokes with a spoke shield,
for example, to minimise the risks.
Smoking when using the wheelchair
should be forgone, as the seat and back sys-
tem may be damaged due to dropping ash.
14 Lift mechanism – safety instruc-
tions
The product is delivered with a lift mech-
anism that is customised to the user's body
weight. For this reason, the product may only
be used by this user, because the lifting and
lowering behaviour changes when it is used by
other people with a different body weight.
The gas pressure springs must not be
opened or heated. For service or repair work,
inform your rehabilitation specialist dealer or
contact PRO ACTIV.
The lifting movement of the product must
only be executed with the parking brake brake
is applied, the anti-tipping support in active
position, and on a level surface.
The product must not be moved or
pushed by the user or someone else when the
seat is lifted.
While executing the lifting or lowering
movement or when the seat is in a lifted state,
it is essential to observe the following points:
 The upper body must not be tilted to the
front, rear or to the sides beyond the
wheelchair seat (risk of tipping).
 The additional load picked up by the user
must not exceed 10% of the body weight.
The additional load must not be picked up
or put down from/to the side, rather only
from/to the front in an upright seated posi-
tion. During the lifting movement, the load
must be resting on the thighs.
 During the lifting or lowering movement
with the LIFT activ, both hands must be
holding the release handles in the middle,
the fingers must not be spread apart.
 During the lifting or lowering movement
with the LIFT solid, both hands must be
holding the armrests in the middle, the
thumbs must not be spread apart.
 Neither the user nor the accompanying
person may reach under the seat into the
mechanics area of the product.
When using the lift mechanism, the prod-
uct may only be exposed to ambient tempera-
tures between -5 and 40°C. This means, for
example, that use in climatic chambers or in
saunas is not permitted. It is not permitted to
use the lift mechanism near open fires or other
thermal radiators if there is a risk that this tem-
perature can be exceeded.
The product must stand on level, flat and
solid ground. All four wheels must stand se-
curely on the ground, i.e. not in the area of e.g.
thresholds or floor transitions. The traction of

LIFT activ & solid usage instructions
12
the wheels must not be impeded by moisture,
snow, ice, cleaning agents, lubricants, fuel, etc.
Using the product in the water or on sandy or
unsurfaced ground is not permitted.
15 Safety instructions regarding
obstacles
Driving on steps with the product is for-
bidden.
Due to the significantly high risk of tipping
and injury, the product should only be used to
negotiate escalators after participation in a
corresponding safety training course and with
an accompanying person for safety reasons.
The maximum obstacle height which can
be negotiated is 10 cm.
When driving over or passing obstacles, it
is important that you avoid any product or body
parts catching on the obstacle as this may lead
to falls causing serious injuries to the user and
third parties as well as damage to the product.
Always drive over curbs or other obsta-
cles so that you cross them to the front or at
right angles and at the minimum required
speed. When approaching an obstacle at an
angle or driving over it with just one drive
wheel, there is an increased risk of tipping over
sideways.
If the product with the user needs to be
transported over an obstacle and there are
suitable facilities such as a ramp or a lift avail-
able, then these should be used. If such facili-
ties are not available, then the obstacle is to be
overcome by being carried by two helpers.
When carrying the product, it may not be lifted
by the side sections, the drive wheels or the
footrests. We recommend holding the product
on the frame and the back cross bar to carry it.
Before crossing an obstacle (steps,
thresholds, etc.), the anti-tipping supports must
be swivelled (LIFT activ) or plugged (LIFT
solid) from the operating to the passive posi-
tion, so that you do not make contact with the
obstacle when crossing, which could cause
you to fall. After crossing the obstacle, the anti-
tipping supports must be immediately returned
to the operating position (Chapter 25).
For overcoming obstacles such as kerbs
or steps, the product needs to be actively
tipped. The caster wheel may otherwise jam at
right angles to the obstacle and could block.
This could damage the caster wheel or the
caster fork and result in injury to the user. If
actively tipping it is not possible, then the ob-
stacle should not be approached or you need
to request assistance from an accompanying
person. Particular attention needs to be paid to
this when using an auxiliary drive.
16 Safety instructions regarding
dangerous locations and dan-
gerous situations
The operator of the product determines the
route to be driven themselves, taking the us-
age instructions, their driving knowledge, and
physical abilities into consideration.
Personal driving skills are particularly important
in the following dangerous locations that are
provided as examples; the product user must
use their judgement before driving in such
locations:
 quay walls, landing and berthing locations,
paths and locations close to water, unse-
cured bridges and dykes.
 narrow paths, slopes (e.g. ramps and
driveways), narrow paths on a slope,
mountainous routes.
 narrow and/or steeply sloping paths along
main roads or near cliffs.
 routes that are covered in leaves, snow or
ice.
 ramps and lifting equipment on vehicles.
When driving in a curve or turning on hills
or downward slopes, there may be an in-
creased tendency to tip over to the side due to

LIFT activ & solid usage instructions
13
the changes in the centre of gravity. Avoid
such driving manoeuvres. If these cannot be
avoided, perform these driving manoeuvres
with increased caution and only at a very slow
speed. If necessary, the driving manoeuvre
must not be performed or only with the help of
an assistant.
Use particular caution when approaching
stairs, edges, drops or other hazard areas.
Extreme caution is needed when crossing
main roads, intersections and level crossings.
Rails in the road or level crossings must never
be crossed when travelling parallel to them, as
otherwise the wheels could become caught
which would result in the product being unable
to manoeuvre.
Extreme caution is needed when driving
on ramps and lifting equipment on vehicles.
Ensure in advance that the ramp is wide
enough so that you do not risk the product
wheels slipping off the ramp. When lifting or
lowering a ramp or lifting equipment, the park-
ing brake of the product should be applied.
Always keep the product in the middle of the
ramp.
The grip of the tyres on the ground is
reduced under wet conditions. There is an
increased risk of slipping. Adjust your driving,
braking and steering behaviour accordingly.
17 Safety instructions –
after driving/use
Apply the parking brake before getting out
of the product.
When getting out of the wheelchair, do
not tread on the footrest due to the risk of tip-
ping over.
When getting out of the wheelchair, do
not support yourself on the clothing guard (risk
of pinching).
18 Individual setting options
The following instructions are intended for
and may only be carried out by a rehabilitation
specialist dealer or PRO ACTIV
18.1 Adapting the seat height at the
back (LIFT solid)
Adapting the seat height at the back is only
possible on the LIFT solid.
The seat height at the back results from the
choice of the drive wheel plate. Subsequent
changes can only be made by replacing the
drive wheel plate. In this case, contact your
rehabilitation specialist dealer or PRO ACTIV.
18.2 Adapting the seat height at the
front/the seat angle (LIFT solid)
Adapting the seat height at the front or the seat
angle is only possible on the LIFT solid.
If the seat height has to be adjusted, the angle
of the seat or the front seat height can be ad-
justed. This setting is carried out via the posi-
tion of the caster wheels in the caster wheel
fork and the caster fork size.
18.2.1 Adapting by positioning the caster
wheels in the caster fork
Adjusting the front seat height or angle of seat
can be carried out via the positioning of the
caster wheel in the caster fork. Generally, the
caster forks have three possible positions that
can be used to change the front seat height in
steps of 15 mm.
 If the seat inclination or the front seat
height are to be increased, the caster
wheel is mounted in a lower position in the
caster fork.
 If the seat inclination or the front seat
height are to be reduced, the caster wheel
is mounted in a higher position in the cast-
er fork.

The instructions for disassembly and assembly
of the caster wheels can be found in chapter
23.1.
18.2.2 Adaptation by replacing the caster
fork
If the adjustment range of the existing caster
fork is insufficient, the next larger or smaller
one can be used.
In doing so, the bottom position of the fork size
1 is equivalent to the top position of fork size 2
and the bottom position of fork size 2 to the top
position of fork size 3.
Figure 2: Caster fork sizes with marking of the same
seat height settings with different caster fork sizes
The instructions for replacing the caster forks
can be found in chapter 23.3.
18.2.3 General instructions
When changing the angle of seat or front seat
height each time:
 the wheel track of the drive wheels must
be checked and readjusted if necessary
(see Chapter 22.2).
 the caster wheel axles must be readjusted
(see Chapter 23.4) (LIFT solid).
 the backrest angle may have to be reposi-
tioned (see Chapter 19.2).
 make sure that there is sufficient ground
clearance under the footrest. Experience
shows that this should not be less than
4 cm (see Chapter 24).
18.3 Adjusting the tipping point
Optimum product tipping behaviour is
achieved when the axle mount of the drive
wheels is close to the body centre of gravity. A
product adjusted like this can be driven with
little effort and it also makes it possible to

manage a slightly uneven surface or edges by
tipping slightly. Driving on both drive wheels
(doing a wheelie) is relatively easy to learn.
Inexperienced wheelchair users must be pre-
vented from tipping over backwards by means
of anti-tipping supports.
To ensure safe operation, the tipping point
setting should always be selected to suit the
wheelchair user's individual requirements and
abilities.
18.3.1 Adaptation on the LIFT activ
Using the M6 hexagon screws (AF 10 mm; Fig.
4), the tipping point can be adjusted in 1 cm
increments within a range from 6 cm to 10 cm.
Figure 3: Seat unit on the wheelchair
Figure 4: Seat unit with hexagon screws
To adjust the tipping point, proceed as follows:
1. Loosen the four M6 hexagon screws (AF
10 mm) on both sides (Fig. 4).
2. Sliding the seat unit (Fig. 3) to the rear
increases the tipping point. Otherwise, it is
reduced.
3. Fix the new position by tightening the four
M6 hexagon screws with a tightening
torque of 7 Nm.
18.3.2 Adaptation on the LIFT solid
Figure 5: Wheel plate with drive wheel bushing

ing nut (rear view)
To adjust the tipping point, proceed as follows:
1. Loosen the aluminium locking nuts (AF
41 mm).
2. Slide the drive wheel bushing in the slot
(Fig. 5) to the desired position. Sliding it to
the front increases the tipping point. Oth-
erwise, it is reduced.
3. When the desired position has been found,
hold the drive wheel bushing in position us-
ing the open-end spanner (AF 22 mm) and
tighten the aluminium locking nuts (AF
41 mm) with a tightening torque of 70 Nm.

18.3.3 General instructions
After each change to the tipping point:
 the wheel track of the drive wheels must
be checked and readjusted if necessary
(see Chapter 22.2).
 the caster wheel axles must be readjusted
(see Chapter 23.4) (LIFT solid).
 the brakes must be readjusted (see Chap-
ter 26).
Extreme settings such as drive wheels
mounted far to the front or a seat frame
mounted for the back are only permitted for
experienced wheelchair users who are able to
actively shift their weight forwards during oper-
ation.
To minimise the risk of tipping backwards,
we recommend using anti-tipping supports,
even with anti-tipping settings.
19 Back system
Avoid falling into the seating and backrest
upholstery/back shell as it significantly in-
creases the risk of changing the adjustment,
falling down or defects.
19.1 Lumbar support/curvature
19.1.1 Back tube with lumbar joint (LIFT
activ)
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
Figure 7: Back tube with lumbar joint
Figure 8: Lumbar joint with different lumbar depth
(viewed removed from the product)
The lumbar depth can be adjusted between 1,
2 and 3 cm by using tools.
To adjust the lumbar depth, loosen the M5
fixing screws (AF 3 mm) on both sides (Fig. 9)
and pull the lumbar joint out of the back tubes.

Then pull out the cylindrical pin on both sides
and position the lumbar joint in the desired
position (Fig. 10).
Figure 10: Lumbar joint with view from the inside
(left) and from the outside (right)
In the next step, fix the position by inserting the
cylindrical pin in the desired hole position.
Finally, now slide the lumbar joints back into
the back tubes and screw the lumbar joints
onto the back tubes with the M5 fixing screws
(AF 3 mm) with a torque of 6 Nm (Fig. 10).
19.1.2 Back tube with lumbar curvature
Figure 11: Back tube with lumbar curvature (LIFT

The backrest can be freely selected with a
lumbar depth of 1, 2 or 3 cm. There is no sub-
sequent adjustment option.
19.2 Backrest angle
19.2.1 Adjustment option for folding
backrest
Figure 12: Side section with folding backrest (lifted
up)
If equipped with an adjustable and foldable
backrest, the backrest angle can be flexibly
adjusted without using tools and the backrest
can be completely folded away. The angle of
the backrest can be fixed in 7 positions in 5°
steps.
Observe that the centre of gravity is shift-
ed further to the rear by the enlargement of the
angle between the backrest and the seat sys-
tem and thus, the tipping point of the product is
reached much sooner.
19.2.2 Instructions for sitting posture with
an adjustable backrest
For a good sitting posture, we recommend
positioning the backrest vertical to the ground,
where possible.
With low backrests with adaptable belt cover
due to a disability, it may be advantageous to
slightly tilt the backrest forwards and to slacken
the top belt of the backrest upholstery so that
the slack in the upper area is greater in order
to achieve good sitting stability under certain
circumstances (see Chapter 19.3).
The adjustment possibility of the backrest an-
gle supports active sitting and ensures for flex-
ibility of the wheelchair user. An example in the
following:

 If the angle of the seat has been changed
(see Chapter 19.2), the angle of the
backrest can be respectively readjusted.
 When driving on slopes and when trans-
porting baggage (e.g. backpacks) on the
backrest, the centre of gravity shifts more
to the rear and the risk of tipping increas-
es. Then this can be counteracted by a re-
spective angle adjustment of the backrest
to the front.
 For comfortable seating, the backrest can
be locked in a position to the rear so that
the backrest is tilted slightly back.
19.2.3 Adaptation of the backrest angle for
the folding backrest
To adjust the backrest angle, relieve it (oth-
erwise there is a risk of tipping) and then loos-
en the locking pins that engage in the locking
holes of the side sections on the left and right.
For this purpose, grasp under the seat cover
and in the middle, pull the cord to the front that
is linked to the locking pin.
Figure 13: Locking pin connected to a cord (view
from inner side of product)
Figure 14: Locking pin engages in the locking hole
in the side section (view from outer side of product,
without clothing guard)
Figure 15: Cord for operating the locking pin and
thus for adjusting the angle of the backrest
If you have released both locking pins by pull-
ing on the cord, you can adjust the backrest as
desired and re-engage it by letting go of the
cord. In doing so, before applying load again,
make sure that both locking pins have en-
gaged safely into the desired locking holes (the
same position on the right and left).
A stop pin may be mounted in the backrest
angle adjustment range as a limiter.

Depending on the adjustment of the
backrest angle, check the tight engagement of
the backrest via the locking pins.
To fold down the backrest, pull on the middle
of the cord towards the front, and at the same
time, fold the backrest downwards until it rests
on the seating area. If you want to return the
backrest to the desired angle, proceed as de-
scribed at the beginning of backrest angle
adjustment.

19.3 Adjustable back & its adjustment
options
The "adjustable back and back padding" back
system consists of a belt system and back
padding. The slack of the backrest can be
adapted to the individual requirements via the
belts with tensioning loops.
First remove the back padding that has been
covered over which has been attached using
hook-and-loop straps. The belt system located
underneath has been set in the factory that the
top and the bottom belts have a slack of ap-
prox. 2 cm. The middle belts have been pulled
tight for a good lumbar support.
