Page 9
1. Important points to note before operating the LEVO active-easy LAE
Before using the LEVO active-easy, either study the instruction manual yourself or have your
LEVO dealer explain the instructions to you.
Standing up stresses your body in ways you may not be used to. Therefore we recommend you
consult your doctor or physical therapist before using the LEVO active-easy.
The LEVO active-easy should only be brought into the stand-up position on firm, level ground (risk
of tipping over).
The LEVO active-easy should only be brought into the stand-up position with the brakes on.
The stand-up mechanism should only be operated when the LEVO active-easy is occupied (risk of
accident).
Before standing up it is absolutely vital that the knee support and chest strap are fitted correctly (see
section C.4.). You should under no circumstances attempt to stand up without these safety restraints
securely in place (risk of accident).
In the case of strong or sudden spasms, cramps or similar the user should only stand up under
supervision of a carer.
Adjustments to the stand-up mechanism and its connected parts are to be carried out by qualified
technicians (risk of accidents).
Should you require adjustments and alterations to the mechanics of the wheelchair, or any
maintenance work, please contact your LEVO dealer.
2. Warranty
Your LEVO product is guaranteed from the date of purchase for two years covering all material and
manufacturing defects of mechanical parts.
LEVO AG will not repair or replace free of charge any part or parts found to be defective due to
abuse, misuse or lack of maintenance.
Warranty claims should be directed to:
• In Switzerland = LEVO AG
• Other Countries = To your local agent
Addresses and telephone numbers are given on the front page.

Page 10
3. Sitting / Driving
In the LEVO active-easy you will enjoy all the handling qualities and comfort of an active
wheelchair. This section will tell you how to adapt the LEVO active-easy to suit your particular
needs. Before attempting adjustments yourself, please consult your LEVO dealer.
3.1. The rear wheels
High pressure tires are fitted as standard on the LEVO active-easy. The diameter of the wheels
depends on the height of the seat. Thanks to the quick-release axles, the rear wheels can be easily
removed and set back in place (see photo left).
3.2. Seat inclination
The standard pre-set angle of inclination is 5° to the rear. By altering the height of the axle adapter
it is possible to re-set this angle to anything between 0° (horizontal) and 8° to the rear (see photo
above right). To ensure these alterations do not compromise safety in the standing position, the
front wheel forks must be adjusted appropriately. These adjustments should only be carried out
in consultation with your LEVO dealer!
3.3. Position of the rear wheels
By re-setting the axle adapter either further forward or further back, you are able to increase or
decrease respectively your LEVO active-easy’s tendency to tip over (see photo). To avoid accidents
(tipping over) we recommend the fitting of anti-tip rollers (see accessories). Please consult your
LEVO dealer!
10
Page 11
3.4. Position of the front castors
The correct positioning of the front castors depends on the height of the rear wheels and is crucial in
ensuring a safe standing position. Please consult your LEVO dealer!
3.5. Backrest angle
The standard pre-set angle between backrest and seat is 90°. It is possible to re-set this angle either
5° further forward or 5° further back. Please consult your LEVO dealer!
3.6. The footrest
The height of the footrest is adjustable (see left photo) and should be altered in line with your body
proportions to guarantee the best standing position possible. Footrest adjustment should also take
account of your choice of seat cushion. Please consult your LEVO dealer!
The angle of the footrest can similarly be adjusted by plus/minus 5° (see right photo).
3.7. The calf/heel strap
The purpose of the calf/heel strap is to prevent the legs and/or feet slipping backwards. It is fitted
behind the heels or higher (see photo). By making use of the velcro fastening it is possible to alter
the length of the strap and thus to ensure the ideal position for the feet on the footrest. Ideal
positioning of the feet is vital in ensuring a good standing position. Please consult your LEVO
dealer!
11
Page 12
3.8. The seat cushion
There is a choice of various different seat cushions, governed by your individual needs. The velcro
fasteners fitted to the surface of your seat should allow you to attach the majority of seat cushions
securely. The velcro fasteners prevent the cushion from slipping out of place even when you are
standing up. The height of the footrest should be adjusted to take into account the height of a given
seat cushion. Please consult your LEVO dealer!
4. General tips on handling a wheelchair
4.1. Pushing off - how to avoid tipping over
Bear in mind that when pushing on the handring to start the wheelchair moving, the front castors
will loose traction due to acceleration. Depending on weight distribution, this may cause the castors
to lift off the ground and the wheelchair to tip over backwards (see diagram, left).
This above situation may be made more critical by using different rear wheel positions to achieve
greater seat inclination, by fixing the rear wheel further forward, or by using a cushion to sit higher
up.
Similarly, when braking to halt backward movement the castors will again lose downforce, giving
rise to backward tilting and the risk of tipping over.
It should also be noted that any luggage taken along (see diagram, above right) will alter the center
of gravity of your wheelchair and may have an adverse effect on its stability.
As an additional safety measure, it may be advisable to fit anti-tip rollers (see diagram).
12
Page 13
4.2. Gradients
When turning on a gradient, bear in mind you will have to sit square on to the slope before finally
swiveling around to face straight downhill. In this side-on position there is a risk of slipping
sideways down the slope. Either you or your accompanying person should take this risk into
account and steer accordingly to compensate. Always make it a rule to sit leaning into the hill,
however steep the gradient and whichever the intended direction of travel (see diagram).
As a safety precaution, always ask an able-bodied person to accompany you when manoeuvrring
down a slope. Bear in mind that slowing the wheelchair with the handrings generates a great deal of
heat between hands and handring and can lead to burns on the hands. Therefore proceed cautiously
when braking by hand and, most importantly, when travelling downhill, never go faster then
walking pace. Leaning back into the hill improves stability and increases rear wheel downforce,
thus also improving braking efficiency.
4.3. Negotiating obstacles
Any obstacle, such as a kerb or threshold, should be viewed as a potential source of danger. This is
due, in part, to the very short wheelbase of the wheelchair. To negotiate an obstacle, ask an ablebodied person for assistance.
Should you wish to negotiate such an obstacle with the help of an able-bodied person, the latter
should not, as a rule, attempt to lift the LEVO active-easy completely clear of the steps. Rather he
should ensure that the rear wheels stay in contact with the steps at all times.
To surmount an obstacle (e.g. driving up over the kerb from the street), first tilt the wheelchair just
enough to lift the front castors up onto the edge of the obstacle. Push on until the large wheels are
resting against the lip of the obstacle, then lift them up and onto it by taking hold of either the
backrest or the rear axle (see diagram, left).
13
Page 14
To descend down over an obstacle (e.g. driving down from the kerb into the street), first tilt the
wheelchair up onto the rear wheels, then push on and let the wheelchair down over the edge of the
obstacle on two wheels (see diagram, above right).
Should you have to be carried over three steps or more, request the assistance of at least two ablebodied persons. Those assisting should only take hold of solid parts of the frame. They should
under no circumstances take hold of any moving parts, such as the rear wheels or front castors (see
diagram, left).
Proceed with great caution should you wish to overcome an obstacle alone. You should be aware of
the tendency of the wheelchair to tip over backwards if, as the rear wheels contact the edge of the
obstacle, you attempt to surmount it by pushing down harder on the handring (see diagram, above
right).
Never drive your wheelchair onto an escalator.
4.4. Braking with the pressure brakes
When using the wheelchair in situations where increased stability is particularly important, always
remember to apply the brakes (see diagram). This applies, for example, when standing up, sliding
over into your wheelchair or when you want to transfer from the wheelchair into another seat. For
safety reasons, it is particularly important to note that, when transferring, even if the rear wheels are
locked by the brakes, the wheelchair can easily slip sideways if it is not carrying a load.
Keep in mind that insufficient tire pressure or heavily worn tire tread has a detrimental effect on
braking efficiency.
14
Page 15
After driving through a puddle, keep in mind that wet tires reduce braking efficiency as water on
the surface of the tires acts as a lubricant.
4.5. Picking up objects from the wheelchair
Always remember that picking up objects from the wheelchair will alter your center of gravity and
effect stability. This can cause the wheelchair to tip over, either backwards (see diagram, left),
sideways or forwards. In the latter case, to decrease the likelihood of tipping forwards, enlarge the
wheelbase by pointing the castors as if the wheelchair were moving backwards (see diagram, right).
It is also advisable to draw as near as possible to the object before attempting to pick it up.
4.6. Detachable components
You will be pleased to know that your wheelchair is designed to be fully collapsable and is built
with several detachable components to guarantee the lowest possible packing volume and weight.
Certain movements involved in folding down the backrest are, by their very nature, potentially
harmful. Please take care not to trap any clothing or parts of the body in the joints of the wheelchair
as your are folding down the backrest. You should only resume your seat in the wheelchair once it
has been fully unfolded and reassembled with all detachable components (e.g. rear wheels and
castors) once again securely fixed in place. Always make sure beyond any doubt that the rear
wheels have been securely reattached, and cannot work loose while the wheelchair is moving (see
diagram).
15
Page 16
4.7. Transport in a motor vehicle
When transporting the wheelchair in a motor vehicle make sure that the wheelchair is so secured as
to prevent it sliding about or tipping over. Use should be made of licensed fastening systems which
secure the wheelchair’s rear axle and at the front the lower frame tubes from below.
It is not permitted to transport the wheelchair in a motor vehicle when somebody is still sitting in
the wheelchair.
5. The brakes (wheel locks)
The brakes lock the rear wheels fast and your LEVO active-easy is secure against unintended
movement.
By pushing both brake levers forwards as far as they will go, you should be able to lock the brakes.
The efficiency of the brakes is dependent on tire pressure and profile, which should be checked
regularly (see section 12. Maintenance).
Caution: wet tires or surfaces also have a detrimental effect on brake efficiency.
When altering the position of the wheel axle, be sure to re-adjust the brakes too.
5.1. Adjusting the brakes
The wheelchair should be unoccupied when dismantling the brakes. Secure the wheelchair in such a
way as to prevent it moving when the brakes are removed.
Relax the brake as far as it will go.
Loosen the cylindrical screw on the brake mounting (see photo, left).
Adjust the position of the brake and the mounting to leave a gap of approximately 10 mm between
brake shoe and tire, then screw the cylindrical screw tight again (see photo, above right).
Test the strength of the brake.
Should you need to tighten up the brakes, set the brake shoe closer to the tire. To relax brake
tension, leave a larger gap between shoe and tire.
16
Page 17
6. Standing
Your LEVO active-easy isn’t just an active wheelchair. It is also a standing aid which enables you
to stand up simply and quickly, right there, when and where you need to.
General tips
Standing up stresses your body in ways you may not be used to. For this reason, please consult
your doctor or physical therapist before using the LEVO active-easy to make sure you do not
suffer from any conditions (e.g. strong contractures or osteoporosis) which make standing
potentially harmful.
The LEVO active-easy may only be brought into the standing position on firm, level ground (risk of
tipping over).
Before standing up, apply both brakes on the LEVO active-easy.
Please beware of parts of the wheelchair where one might conceivably trap or catch parts of the
body when standing up, in the space between the side panel and the seat as well as in the pivot of
the side panel. Be sure to protect yourself and accompanying persons from possible injury.
7. The knee support and chest strap
The most important safety features of the LEVO active-easy are the knee support and the
chest strap. It is absolutely essential that these be correctly in place before you attempt to
stand up (risk of accident).
7.1. The knee support
The knee support holds the knees in an extended posture and prevents you slipping out of the
wheelchair while standing up.
Attach the two eyes of the knee support to the double-head screws on either side of the wheelchair
(see photo left).
Center the knee support in front of each knee using the velcro fasteners, then pull it until it is sitting
firmly in place, just below (not right on) the knee cap and not too tight (see photo above right).
17
Page 18
7.2. The chest strap
The chest strap holds the upper body in place.
Check that the chest strap is secure on the backrest (velcro fastening).
Close the catch on the chest strap and pull it to (not too tight, see photo).
To release the chest strap, simply press the red button in the center of the catch.
To slacken, hold the catch at a right angle to the strap and pull.
Once the knee support and chest strap are fitted correctly you are ready to stand up.
8. Standing up
The two armrests on either side of the seat serve not only as armrests, but also as a part of the standup mechanism.
There are four release levers. The bigger ones in the rear of the armrest are the gas spring-release
levers (marked with Symbol 1). They release the gas springs which assist you as you raise yourself
up by pushing down lightly on the side panels.
The two smaller ones more in the front of the armrest are the armrest-release levers (marked with
Symbol 2). By using these levers the armrests can be brought higher up or lowered.

18
Page 19
8.2. Having raised yourself up as far as your arms will allow, let go of the gas spring-release
levers to lock the gas springs once more in place (see photo above right).
By using the two armrest-release levers found further toward the front of the armrests, you can
bring the armrests up to the appropriate height.
8.3. Pull the two armrest-release levers, then lift the two armrests. Let go of the armrest-release
levers and pull the two armrests up until they click in (see photo left).
8.4. Repeats points 8.1. - 8.3. (see photo above right) until you are standing fully upright. The
leg supports should be in contact with the ground.
9. Sitting down
9.1. To unlock the gas springs again, first push forward the little latch to be found on gas springrelease levers, then pull the release levers themselves (see photo 8.1.). Continue to hold down the
release-levers as you use the armrests to pull yourself downwards.
9.2. Let go of the gas spring-release levers and, making use of the armrest-release levers, lower
the armrests (see photo 8.3.) into their intermediate position.
9.3. Repeat steps 9.1. and 9.2. until you are once again able to resume your seat.
Attention: Lower yourself slowly to the lowest seated position! Risk of tipping over!
19
Page 20
10. The gas springs
The gas springs are specially adjusted to hold your weight in the balance. With minimal arm work,
i.e. pushing lightly on the armrests, you can stand yourself up. Similarly, by pulling lightly you can
sit yourself back down in your seat, equally effortlessly.
There is a range of spring strengths to suit the body weight of different wheelchair users.
The gas springs may be adjusted by no other than a qualified technician! Please consult your
LEVO dealer!
Caution: do not bend or stretch the cables leading from the armrests to the gas springs as this
may unintentionally trigger the stand-up mechanism (risk of accident)!
11. Storage
11.1. Folding down the backrest
Your LEVO active-easy is equipped with a collapsable backrest which allows you to cut down
significantly on the space required to store the wheelchair away.
Push up the two folding clasps and at the same time push the seatback forwards (see photo).
You may wish to fit a chord to connect the wheelchair’s two folding clasps. If you have fitted a
chord, pull it toward the rear and upwards while pressing the backrest lightly forwards.
12. The quick-release axles
The quick-release axles enable you speedily to remove and re-mount the rear wheels of your LEVO
active-easy, thus reducing significantly the volume and weight of the wheelchair.
When removing a wheel, the wheelchair must be unoccupied. The wheelchair should be supported
in such a way that it neither falls over nor rolls away after removing the wheel.
12.1. Depress the release button in the center of the wheel, then pull off or re-mount the wheel
(see section 3.1., The rear wheels).
20
Page 21
12.2. Having mounted the wheel, push and pull it several times to ensure the quick-release axle
has definitely locked in.
13. The castors
To remove the front castor together with the front forks, depress the quick-release axle from
underneath, then pull off the forks (see photo).
14. Maintenance
To keep your LEVO active-easy in good condition, it is advisable to adhere to the following
guidelines and to carry out maintenance work on a regular basis, as detailed below.
A life-long lubricant is applied to your LEVO active-easy dispensing with the need for later
restorative lubrication and oiling.
When cleaning your LEVO active-easy, use a dry or slightly moistened cloth to wipe the
wheelchair down. For stubborn or oily stains, apply a mild detergent to the cloth. Do not hose down
your LEVO active-easy with water (risk of rusting).
According to frequency of use, check tire pressure between once a week and once a month. If
necessary, pump up the tires in line with manufacturer’s recommendations (see section 16.
„Technical Data).
Check the state of the tread on the tires every one to six months. If a tire is heavily or unevenly
worn, it should be replaced. Please consult your LEVO dealer!
Every one to six months, check that the brakes still work cleanly. Having applied the brakes, the
wheels should stop turning completely. If the brakes are ineffective, they should be tightened up
(see section 5.1. Adjusting the brakes). Please consult your LEVO dealer!
14.1. For the first month, check cable tension on the gas spring-release once a week. You should
re-adjust cable tension either weekly or monthly, depending on how often you use the stand-up
facility.
14.2. Check that the gas springs lock and release correctly when you press the release as part of
the stand-up procedure.
21
Page 22
If the gas springs are sluggish on release, have them adjusted by a qualified technician. He will
have to loosen the counter nut and turn the adjustment screw one turn to the left (anti-clockwise),
(see photo, over).
If the gas springs are not locking properly, have them adjusted by a qualified technician. He will
have to loosen the counter nut and turn the adjustment screw one turn to the right (clockwise), (see
photo).
Repeat 14.2. until the gas springs lock correctly.
Please consult your LEVO dealer when adjusting cable tension!
We recommend you have your dealer service the LEVO active-easy on an annual basis.
15. Disposal
At the end of its service life the wheelchair should be returned to your LEVO dealer for proper
disposal.

• Do not reuse Nyloc nuts. Always replace with a new Nyloc nut.
• Always use thread locking compound.
• Always use recommended components and parts available from LEVO AG.
• Do not modify or repair the frame.
• LEVO AG is responsible for any repairs on gas springs, motors and electronic parts.
7. Recommended safety checks
Please note that the following safety checks should be carried out at least on an annual basis.
Have them carried out only by your LEVO dealer or an authorized technician. If a defect occurs,
immediately discontinue using the wheelchair until the defect is remedied.
1. Fold down the backrest and reset. Having put the backrest back in place, check that the clasp
latches correctly. Rectify possible defects.
2. Check the frame for possible defects. Replace defective parts if in need of repair.
3. Check seat and backrest covers for possible wear and replace, if necessary.
4. Check the condition of straps, belts and catches and replace, if necessary.
5. Check that nuts, screws, joints and plastic parts are securely tightened as well as for proper
condition. Rectify possible defects.
6. Check that push handles and handle covers fit tightly. Rectify possible defects.
7. Check brakes for adequate braking efficiency. Rectify possible defects.
8. Check that front castors and rear wheels run smoothly and are securely fastened. Check tire
pressure and the tread of the tire of rear wheels.
9. Check the stand-up mechanism and its proper operation. Rectify possible defects.
10. For the first month, check cable tension on the gas spring-release once a week. You should re-
adjust cable tension either weekly or monthly, depending on how often you use the stand-up
facility.
11. Check that the gas springs lock and release correctly when you depress the lift activator as
part of the stand-up procedure.

8. Adjustments
8.1. The backrest and seat upholstery
The surface flexibility of the backrest upholstery can be adjusted using the velcro fasteners. The
backrest can be tightened (for a more upright seated posture) or relaxed (for more back support).
The seat upholstery can be similarly tightened or relaxed by use of velcro fasteners. As a rule it
should be as taut as possible. Depending on the height of the cushioning in question, it may be
necessary to loosen upholstery surface tension to be able to sink the cushioning down between the
two seat supports.
The chest trap is fixed to the backrest upholstery by use of velcro fasteners. It can therefor be
adjusted in height.
8.2. Rear wheel position
The axle adapter mounted as standard on your LEVO active-easy depends on the seat depth.
S M L XL
Seat depth
• Seat depth S: axle adapter S mounted.
• Seat depth M: axle adapter M mounted.
• Seat depth L: axle adapter L mounted in forward direction.
• Seat depth XL: axle adapter L mounted in rearward direction.
See also illustration 1.

Axle adapter
• Seat height 48 cm (22” wheels) and 51 cm (24” wheels): axle
adapter mounted at 45 mm from lower end of frame tube. Seat
height 54 cm (24” wheels): 20 mm, seat height 57 cm (26”
wheels): 30 mm.
To adjust the seat inclination the axle adapter is adjusted in height:
• Unscrew both inside hexagonal screws (A) using a 10 mm
A
spanner and tighten the threaded pin (B) using a 3 mm Allen key
(see photo 2). The latter opens up the clamps on the axle
adapter.
• Adjust the axle adapter to the desired height, unscrew the
threaded pin and tighten the two inner hexagonal screws again.
2
B
Caution: When adjusting the height of the axle adapter, be sure to adjust the castor height and
angle accordingly (see section 8.3.). In case of large scale adjustments it may even be necessary to
replace the leg supports.
Having made the adjustments, it is absolutely vital to ensure that, when standing up, the leg
supports still rest on the ground as this is crucial to standing ability (risk of accident!)!
26
Page 27
8.3. The castor axle
Having made adjustments to the rear axle, be sure to adjust the castor height and angle accordingly.
When carrying out these adjustments, it is important to bear the following points in mind:
• The castor axle should stand at a right angle to the ground.
• The castor should always remain in contact with the ground.
• In the uppermost standing position, the leg supports must be resting on the ground.
• Bring the LEVO active-easy into the standing position.
• Unscrew and remove the cylindrical screws using a 4 mm Allen
key, then set the plastic leg plug either higher or lower so that
the leg supports are standing on the ground. You may have to
turn the leg plug by 90°. (se photo 3).
3
• Unscrew the two cylindrical screws using a 5 mm Allen key and
turn the eccentric disc until the axle is sitting vertically (see
photo 4). You may have to turn only one of the two eccentric
discs. Screw the cylindrical screws tight.
4
8.4. The leg supports
The leg supports should be replaced when the seat height of the wheelchair has been so greatly
adjusted that they no longer reach the ground or reach the ground too soon in the uppermost
standing position.
• Remove the rear wheels (see Instruction Manual, section B.1.)
• Remove the footrest (see section 8.6.).
• Loosen the cylindrical screws on both inner sides of the leg
supports and remove them together with the spacer bushing (see
photo 5). Then pull the leg supports out of the frame.
• Replace the leg supports and reassemble in reverse order.

27
Page 28
8.5. Backrest angle
The backrest sits at an angle of 90° to the seat as standard but can be adjusted in either direction by
5°. This adjusting mechanism is not stepless.
• Remove the rear wheels, then remove the skirt guards (see
Instruction Manual, section 3.1.).
• Unscrew the countersunk screw on the outer joint using a 4 mm
Allen key, remove the screw and the bushing (see photo 6)
before adjusting to the desired position and tightening up the
countersunk screw.
6
Attention: Having adjusted the backrest angle, check that the clasp of the folding mechanism
latches correctly!
8.6. The footrest
The height of the footrest is not only important for a good sitting position but even more so for the
standing position. On delivery you will find the footrest at the second lowest position, if not ordered
specifically.
• There is a choice of 5 different heights for mounting the
footrest.
• Unscrew the four oval head screws on both outer edges of the
footrest using a 4 mm Allen key and set the footrest either
higher up or lower down (see photo 7).
7
There are three possible footrest angle variations:
• 4° to the horizontal
• 14° to the horizontal (standard)
• 24° to the horizontal
• Unscrew the four oval head screws on both outer edges of the
footrest using a 4 mm Allen key and remove the upper ones.
Setthe footrest at the desired angle and retighten the screws (see
photo 8).
8
28
Page 29
The footrest angle is set as standard at 14° to the horizontal. With the footrest in the lowest possible
setting, an angle of 4° is the only practicable variation as the footrest otherwise touches the ground
before the leg supports (hence no standing stability!).
With the second lowest setting the only potential variations are 4° and 14°, for the same reasons.
For all higher footrest settings there is a choice of all three angle variations.
8.7. Adjusting the gas spring release
It is important to check that the gas springs respond to the gas spring release lever and lock and
release correctly as part of the standing up.
Caution: When checking the gas spring release, the gas springs should be extended, i.e. the
wheelchair should be in a standing position! Risk of accident!
• If the gas springs are sluggish on release, the cable tension is not
tight enough. Loosen the counter nut (A) using a 10 mm Allen
A
key and turn the adjustment screw (B) one turn to the left using
a 8 mm spanner (anti-clockwise).
B
• If the gas springs are not locking properly, the cable tension is
too tight. Loosen the counter nut (A) and turn the adjustment
screw (B) one turn to the right (clockwise).
• Repeat until the gas springs lock correctly.
• See also section 9.5., Important check.

9. Repairs
9.1. Replacing tire/inner tube of rear wheels
• Remove the wheel and open the valve before pressing down on
it to let out the air (see photo 10).
• Using a bicycle tire wedge, ease both sides of the tire over the
wheel rim and pull the inner tube out of the tire (see photo 11).
• Replace the inner tube by forcing one side of the tire back over
the wheel rim, pump up the tire a little, ease the valve through
10
into the hole and lay the inner tube along inside of the tire. Once
the whole tube is snug inside the tire, force the other side of the
tire back over the wheel rim (starting on the side opposite the
valve).
• Check lest the inner tube be caught between tire and rim before
pumping it up in line with the manufacturer’s recommended tire
pressure (see Technical Data, section 12).
11
29
Page 30
9.2. Repairing the inner tube
• Remove inner tube and tire following the steps described under
9.1.
• Repair the hole using a bicycle puncture repair kit and follow
the manufacturer’s instructions (clean the area around the hole
and roughen the tube surface (see photo 12) before applying the
vulcanized solution. Allow to dry, then firmly attach the rubber
12
patch (see photo 13). Again, first allow to dry, then pump up the
tube to check that the patch is airtight).
• Replace the inner tube. Once the whole tube is snug inside the
tire, force the tire back over the wheel rim (starting on the side
opposite the valve).
• Check lest the inner tube be caught between tire and rim before
pumping it up in line with the manufacturer’s recommended tire
pressure (see Technical Data, section 12).
13
9.3. Replacing the axle adapter
There are a variety of axle adapters available by use of which the wheel axle can be set further
forward or further back to increase or decrease respectively the tendency of the wheelchair to tip
over, see section 8.2..
14 A B
C C
• Loosen the inside (A) and top (B, on the right hand side, but
bottom on the left) hexagonal screws using a 10 mm spanner,
then tighten both threaded pins (C) using a 3 mm Allen key (see
photo 14).
• Slide the axle adapter off the tubular frame and the axle itself
and replace it.
• Set the new axle adapter to the desired height, loosen the two
threaded pins and screw the two hexagonal screws tight.
30
Page 31
9.4. Replacing the gas springs
Should you have to replace the gas springs, for example, to boost or reduce their resistance, ensure
first that they are not extended (too long, i.e. the wheelchair should be in half seated or almost
upright position, but not in the fully upright standing position). It is important that the gas springs
are the same length.
• Unscrew the gas springs on both sides simultaneously turning
15
them to the right (clockwise) to remove them from the rear gas
spring holders (see photo 15).
A
• Unscrew the counter nut (A) on the front of the spring using a
17 mm spanner and unscrew the spring to remove it from the
front gas spring holder (B) (see photo 16).
B
• The new gas springs should have the same length, but not be
fully extended. Mount in reverse order.
16
9.5. Replacing the gas spring release cable
Caution: When replacing one or both gas spring release cables, the gas springs should be extended,
i.e. the wheelchair should be in a standing position! Risk of accident!
• Remove the small cover by unscrewing the three countersunk
screws using a 2.5 mm Allen key.
17
• Loosen and remove the threaded pin (C) and the countersunk
screw (D) using a 4 mm and 6 mm Allen key (see photo 18).
Take off the complete armrest.

out. Remove the cable coating as well as the adjustment screw
(I) and the counter nut (A) using a 8 mm and 10 mm spanner
(see photo 20).
20
• Mounting the new cable:
F
J
Insert the new gas spring release cable (J) through the release
lever (F) and into the armrest towards the rear and down in
direction of the arrow (see photo 21).
• Insert the release lever (F) into the armrest: Attention: the other
21
cable, the one of the armrest release mechanism, must run lateral
of the gas spring release lever! It must not run above the gas
spring release lever!
• Mount the armrest in reverse order. Don’t tighten the counter sunk screw (D) too much, so that
the armrest can be moved easily up and down.
• Insert the cable again through the cable coating and the adjustment screw (I), then into the gas
spring holder (B). The adjustment screw should have a distance of approx. 3 mm to the counter
nut (A).
• Pull the cable out of the trigger lever (H) thus far that the trigger lever may till be moved easily.
It should stick out of the gas spring holder (B) by approx. 5 mm. Then fix the cable tension by
tightening the threaded pin (G).
• Re-mount the small cover using the three oval head screws (see photo 17).
Important check: when moving the visible part of the cable/cable coating the gas spring release
mechanism should not be activated!
• If the gas springs don’t release sufficiently, the trigger lever (H) is not being pulled far enough
into the gas spring holder (B) when the gas spring release lever (F) is pressed. The cable tension
is too sluggish. It must be adjusted, see section 8.7..
• If the gas springs don’t lock sufficiently, the trigger lever (H) sits too deep in the gas spring
holder (B). The cable tension is too tight. It must be adjusted, see section 8.7..
