1. Intoduction
Thank you to choose the LEVO C3.
The LEVO C3 has been designed as a powered stand-up wheelchair for indoor
and outdoor use. As such it belongs to the wheelchair category B.
The LEVO C3 makes it possible to stand-up and to drive in a standing as well as
in a sitting position. This function provides great independence to the user.
This wheelchair is made for everyone whose muscles do not support them to
propel a wheelchair manually. The LEVO C3 is a unique aid for those facing
difficulties in standing and walking.
The LEVO C3 has been designed for older children and adults who will benefit
from motorised mobility and the ability to stand up at will.
The standard model of the LEVO C3 allows comfortable sitting and standing on
every stage between the sitting and the complete standing position. Driving is
possible in all stages.
The front wheels are permanent powered with the same speed as the middle
wheels, which offers a great maneuverability around ramps, obstacles and
uneven ground (4WD). In sitting configuration, the chair is driven by the middle
wheels and the front wheels are lifted up from the floor which causes a very
small turning circle. In standing configuration, the chair is driven by the front
wheels and the middle wheels are lifted up from the floor. This allows also a
great mobility in standing position. In sitting or standing position, the driven
wheels are directly in the centerline of the body.
The seat depth, the armrests and the knee support are stage less adjustable, this
gives an ideal possibility to adjust the chair to the customers’ needs.
The maximum load weight is 140 kilograms or 310 pounds; this includes all
personal belongings carried along too.
Read the safety instructions first, to acquaint yourself with the risks and
dangers that can occur by the use of the wheelchair.
The LEVO C3 is certificated with the -sign. This product corresponds to the
regulations notified as 93/42 EWG.
If we use the male form in the following, the female form is included in this.
All information, images, pictures and specifications were made on the base of the
product information we had at the point in time when we printed the manual.
The images and pictures are type examples they don’t claim to be exact
reproductions of the various parts of the wheelchair.
We reserve ourselves the right to changes of product without previous
announcement.

2. Safety instructions
Before using the LEVO C3, have your LEVO dealer explain the instructions to
so. Don't hesitate to ask for any explanation.
LEVO AG is not responsible for damages to persons or property, who
resulted from the fact that the user or another person ignored the
recommendations, warnings and instructions specified in this manual.
For your own security we recommend to read and obey all the
instructions carefully in this manual.

Be aware of, that your wheelchair can produce electromagnetic emissions and
disturb other devices
The necessary force to push the LEVO C3 manually is higher than you are
used to with other powered wheelchairs. Depending on the floor surface and
the constitution of the person which is pushing the wheelchair, it can be
helpful to have a second person around, to help pushing the wheelchair if
necessary.
If unintended movement or brake release occurs, turn the wheelchair OFF as

2.4. Stand-up function
11
Standing up stresses your body in ways you may not be used to. Therefore we
recommend, consulting your doctor or physical therapist before using the
standing function of the LEVO C3.
It is not recommended to drive long distances in the standing position in
outdoor areas. This function is meant for moving around standing indoors, as
in the kitchen or in the office for examples.
The LEVO C3 is only allowed to bring you into the stand-up position when the
free wheel device is "ON", this guarantees the motor brakes function correctly.
Do not stand-up while the chair is in “free wheel” configuration!
You should only bring the LEVO C3 into standing position, if the chair is on
even, solid ground. If this condition is not ensured, the danger of tilting exists.
It’s absolutely essential to mount the knee support and the chest belt correct
before you use the stand-up function or you are driving (see chapter 5.).
You should under no circumstances attempt to stand up without
following all safety precautions.
Do not lift the wheelchair at mobile parts. This can lead to damages to
property or person and/or damages at the wheelchair.
The chest belt is exclusively intended to hold the torso of the user while
driving and the stand-up function. It is not used to be a protection device at
collisions and/or accidents.
We recommend to stand-up only when in company in case of sudden
spasticity, convulsions and similar problems.

2.7. Servicing and maintenance
The LEVO C3 is a complicated piece of machinery. Do not attempt to maintain
it yourself. For all maintenance work, please contact an authorized dealer. It is
once every year.
You should only use original LEVO spare parts at possible repairs or
modifications. If you use other parts, the function and the security of the
wheelchair can be influenced. This also means that the wheelchair is no longer
covered under warranty.
Programming should only be conducted by healthcare professionals within
depth knowledge of PG Drives electronic control systems. Incorrect
programming could result in an unsafe set-up of a wheelchair for the user.
LEVO accepts no liability for losses of any kind if the drive or stability

5. Electromagnetic interference (EMI)
Important: You must be aware of the effect of electromagnetic
interference (EMI) regarding your LEVO C3. Please study the following
facts carefully.
Electromagnetical interference of transmitter and radio wavelength
Powered wheelchairs might be influenced by strong electromagnetic interference.
This interference is caused by radio and tv stations, amateur radio sets (walkietalkie), two-way radios and mobile phones. Interference (especially of radio
stations) might have an influence on the brakes of a powered wheelchair so that
they get released and so the chair runs away. It could also happen that the
wheelchair starts driving in a not desired direction or the stand-up function could
operate non-requested. There could occur constant damages to the steering
system of the powered wheelchair.
The intensity of power is measured in volt per meter (vpm). All powered
wheelchairs are able to resist to a certain amount of electromagnetic
interference. This is called "level of disruptive strength". The security depends on
the level of disruptive strength; the higher the level the better the protection.
Thanks to modern technology the capability of disruptive strength is up to 20
vpm.
The LEVO C3 standard version (no further measures) is supplied with a
disruptive strength level of 20 vpm.
The LEVO C3 is constructed to resist to a regular level of interference as it occurs
in a household. Beside that there exist a certain number of sources of relatively
strong magnetic fields to which you should stay in a safe distance. Some of these
magnetic fields are obvious and easy to avoid. Some other are not easy to be
realized and it is hard to stay off at times. Please take knowledge of the following
list of sources of interference and avoid getting close to these disruptive factors.
The EMI-risk is reduced to the minimum when you follow these instructions.
The sources of radiated EMI are put in three categories:
Portable sender and receiver on which an aerial is directly mounted.
Examples: CB-radio, walkie-talkie, sender and receiver of alarming systems,
fire alarm, police radio equipment, mobile phone and various private
communication systems.
Please notice: Some mobile phones and similar objects transmit signals as
soon as they are switched on even if they are not in use at the moment!
There have not been any known incidents caused by mobile phones to date.
Mobile sender and receiver of intermediate range, as they are installed in
police cars, fire engines, ambulances and cubs. The aerial is normally fixed on
the outside of the vehicle.
Sender and receiver of a huge range, as radio and TV stations and amateur
radio sets.
Be aware that wireless phones, lap tops, AM/FM-radios, TVs, CD players,
recorders as well as gadgets like razors, hair dryers and so on are only small
24
sources of electromagnetically interference. These objects don't cause any
problems regarding the functionality of the LEVO C3.
Electromagnetical interference in regard to a powered wheelchair
Considering that electromagnetical power reaches high intensity in just a short
time as soon as you get close to the source, it is advised to take especially care
carrying a sender and receiver with you. It might occur that an item as
mentioned gets very close to the controller of the wheelchair and like that
electromagnetic energy gets unintended too close too. In this situation the
electromagnetic energy might influence negatively the function of brakes as well
as the motion characteristics of the wheelchair.
Warning: Your wheelchair can produce electromagnetic emissions as
well and disturb other devices.
If unintended movement or brake release occurs, turn the wheelchair
OFF as soon as it is safe.

6. Driving the wheelchair
6.1. Driving in general
Before starting to drive your wheelchair take time to read all the instructions
regarding the LEVO C3 and to get to know the controls. When first learning to
drive your wheelchair, practice in an area you know well. We suggest a large flat
smooth area such as your living room or the driveway to your home. Do not
attempt to drive the wheelchair in confined areas or where there is traffic until
you are sure you can control the wheelchair safely.
Please note, that the knee support and the chest belt is correctly mounted like
7.1. and 9.9. respectively 7.2..
When driving outdoors always have the seat plate in a horizontal position or
tilted backwards (in case seat angle tilt is an optional function).
Switch on the joystick module and practice driving the wheelchair slowly
forwards, backwards and turning side to side. When you have more confidence
increase the speed and practice until you have mastered driving the wheelchair.
It is possible to drive the wheelchair in the standing position. Speeds are cut to
half the speed as soon as the seat leaves the lowest seat position. When indoors
practice standing up in the wheelchair and slowly driving it across the room.
The wheelchair allows driving absolutely safely in a sitting position on slopes with
a maximum gradient up to 10 degree. When driving up or down steeper slopes
than this or over uneven ground, braking and steering response will be limited
due to reduced traction. On a slope don’t lean out of the wheelchair down the
slope. Driving in a standing is no problem on an even and none angled ground.
A limit switch with some important security features programmed is a standard
of the LEVO C3. In correlation of the current position of the chair and the
inclination of the ground the speed is automatically reduced. In extreme
situations the system prohibits to continuing driving for the safety of the user. It
is be possible to go on as soon as the seat plate is lowered. Please read the
detailed information below.
6.2. Obstacles
Avoid driving your LEVO C3 over obstacles that are higher than 80 mm. The risk
to tilt over raises during you drive over high curbs as well as the risk to damage
your wheelchair.
If you like to pass an obstacle you never drove over before, LEVO recommends
doing this with an assistant, to get used to the reactions of the wheelchair.
Because of the special drive mechanism, obstacles can be overcome in an angle
of 45°.
Drive carefully if you pass an obstacle.

Preparations of the LEVO C3 before using it for car transportation:
1. The chair has to be tight down by using the Q’Straint 4 pt with karabiners or
any restraint system that has been tested and passed the ISO 10542/2
standards.
2. The occupant has to be safely secured by using the Q’Straint Vehicle Anch 3-Pt
or any restraint system that has been tested and passed the ISO 10542/2
standards.
12. Cleaning
Whenever the wheelchair gets dirty it should be cleaned using a damp cloth
and then dried thoroughly.
For more stubborn stains wipe with a damp cloth using a mild solution of
warm water and a mild cleansing agent.
Never use furniture polish, spirit or solvents to clean the frame.
In case of dirt on the seat cushion cover or the back rest cover, you can
remove both of it and wash it softly. Do not wash it warmer than 40 degree
Celsius or according the cleaning instructions on the label inside the
cushion cover.
Caution: Never use high pressure water cleaner.
42
13. Maintenance
13.1. Service
The LEVO C3 is designed to be maintenance free and apart from the items below
does not require attention from the user.
Please note that to maintain safe and efficient operation the wheelchair
should be serviced at least once per year by your LEVO agent or
authorized dealer. This annual service has to be filled into the service
card from the agent/dealer.
The user or their family can easily carry out the following tasks.
Keep the wheelchair clean.
Never store the wheelchair when damp.
Keep the batteries charged to the maximum.
Check if all fittings, harness, etc. are working properly (see section 6. - 8.).
Check operation of motor disengaging lever weekly.
Check operation of all controls daily.
If any faults are found, report them immediately to your agent. He will advise
you whether to continue using the wheelchair or not, and what action you
should take to repair the wheelchair.
13.2. Safety checks
The electronic circuits in your control system have been designed to be
extremely safe and reliable. The on-board microcomputer carries out safety
checks at up to 100 times per second. To supplement this safety monitoring you
should carry out the following periodic checks.
If the control system fails any of these checks, do not use the wheelchair and
contact your service agent.
13.2.1. Daily checks
Joystick: With the control system switched off, check that the joystick is not
bent or damaged and that it returns to the center when you push and
release it. If there is a problem do not continue with the safety checks
and contact your service agent.
43
13.2.2. Weekly checks
Solenoid (parking) brake:
This test should be carried out on a level floor with at least one meter clear space
around the wheelchair.
Switch on the control system.
Check that the battery gauge remains on, or flashes slowly, after one
second.
Push the joystick slowly forwards until you hear the parking brakes
operate.
The chair may start to move.
Immediately release the joystick. You must be able to hear each parking
brake operate within a few seconds.
Repeat the test a further three times, pushing the joystick slowly
backwards, left and right.
Connectors: Make sure that all connectors are securely mated.
Cables: Check and ensure that the condition of all cables and
connectors are OK and without damage.
Joystick gaiter: Check the thin rubber gaiter or boot, around the base of the
joystick shaft, for damaged or splitting. Check visually only,
do not handle the gaiter.
Mounting: Make sure that all the components of the control system are
securely mounted. Do not over tighten any securing screws.
13.3. Spare parts
LEVO AG delivers single parts or modules as spare parts. Your distributor can
provide all spare parts listed for your LEVO C3. You have also the opportunity to
order a spare part list from LEVO AG directly.
44
14. Disposal
Wheelchair:
Return the wheelchair after the product lifetime to the sales point. The dealer will
dispose of it according to local regulations. Regarding the possibilities for
individual adjustments your LEVO C3 might be of use to another stand-up
wheelchair user.
Batteries:
Return old batteries to the sales point of the wheelchair or of the new batteries.
The dealer will dispose of them according to local regulations. Remove the
batteries especially careful, if they could have a damaged casing, because there
is the risk of a chemical burn.
