1. Intoduction
Thank you to choose the LEVO C3.
The LEVO C3has been designed as a powered stand-up wheelchair for indoor
and outdoor use. As such it belongs to the wheelchair category B.
The LEVO C3makes 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 C3is a unique aid for those facing
difficulties in standing and walking.
The LEVO C3has 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 C3allows 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 C3is 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
2.1. General safety instructions
Before using the LEVO C3, have your LEVO dealer explain the instructions to
you. It also helps if you have a friend to listen as well. Study the instruction
manual yourself or if you cannot understand it, get a friend to help you doing
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.
On the LEVO C3you find the following symbols attached:
Warning, risk of pinching! Make sure no parts of the body, clothing
or other items get jammed
Warning, read user’s manual!
Anchorage point for the tie down straps.
Label for the shutdown of the brake release

11
2.2. Operation
2.3. Driving
2.4. Stand-up function
Avoid driving through puddles with the LEVO C3. The wheelchair and
especially electrical components are very sensitive to too much water, some
splashes of water don't harm. (There is a danger of false function regarding
some electrical parts getting too wet.)
The LEVO C3is designed for outdoor and indoor use.
-Whenever you are driving, use the knee support and the chest belt.
-LEVO does not recommend driving the LEVO C3on uneven, soft or steeply
sloping ground.
-Using the LEVO C3 outdoors, switch on the lights at dawn and dusk and in the
dark of course.
Don’t let children drive with the wheelchair without supervision.
The wheelchair is not designated to take along passengers, independently
from the age of the driver.
Look further ahead while driving, so that you have sufficient time to react to
obstacles and avoid accidents in your way.
Pay attention to pedestrians, children, dogs etc. close to and especially in
front of you, since they can stop suddenly or change the direction.
Never switch off the joystick module during driving. Otherwise the wheelchair
will stop abrupt, so that you run the risk, to be thrown forward from the
wheelchair. Just release the joystick to stop the wheelchair from moving.
Consider the road permission regulations; these are different from country to
country. It is usually prescribed by law, which kind of streets can be used for
your purposes. Inquire in this regards at your road traffic licensing
department.
Avoid steep edges, hillside situations or stairs if you push the chair manually
(brake release lever in lower position), because there is a risk to lose the
control over the wheelchair because of its weight and measurements. There is
even the risk that the user can fall out of the wheelchair. To overcome an
obstacle we recommend, using a ramp or an elevator.
Be aware of, that your wheelchair can produce electromagnetic emissions and
disturb other devices
The necessary force to push the LEVO C3manually 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
soon as it is safe.

12
2.5. Safety belt system
2.6. Transportation
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 C3is 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 C3into 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.

13
2.7. Servicing and maintenance
The LEVO C3is a complicated piece of machinery. Do not attempt to maintain
it yourself. For all maintenance work, please contact an authorized dealer. It is
requested that your authorized dealer is in charge to services the wheelchair
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
characteristics of the wheelchair are altered without prior notification and
discussion with LEVO.
All inappropriate changes of the wheelchair and its different systems can lead
to an increased accident risk.
All changes and interventions have to be made by an authorized dealer, if
you’re unsecure about any issue, please ask your dealer first.

3. Preparing the wheelchair for use and operation
3.1. Dispatch and transport
For delivering LEVO wheelchairs they are packed in a cardboard box. The back is
detached and carefully packed. Particularly delicate parts have extra protection
to avoid any damage that could be caused by transportation. All wheelchairs are
transported by lorry or air freight. To ensure no damage during transport the
main fuse is taken / switched off.
Initial operation / Main fuse handling in case of
replacement, transportation and storage
Installation of the
main fuse
Fuse version since April 2011
Before shipping, the 70A main
fuse is taken off. Before using
the chair the main fuse has to
be inserted. You shall do this
also when travelling by air
with this wheelchair.
The main fuse housing is under the chair cover in the rear.
To get access, carefully open the cover as shown above.
Open the fuse cover, insert the fuse which is delivered in a separate plastic bag and snap the
fuse cover back. Now the chair can be brought into standing position to get access to the
fuse cabling. Store the fuse cabling properly above the batteries and the main fuse housing
below the control system under the chairs cover.

The ideal condition to store the LEVO C3is a temperature between –40° and +
60° Celsius (between -30° and +140° Fahrenheit). The humidity should not be
above 90%. Please take care to guarantee these mentioned conditions to provide
a long life time for the LEVO C3.
That the batteries don’t discharge too fast, we recommend to taken respectively
switch off the main fuse (see 3.1.). We also recommend charging the batteries at
least every 2 months if the chair is not used.
3.4. First adjustments
Because the LEVO C3was ordered with your personal measurements, it should
fit your personal constitution when the chair is delivered to you. If there should
be any variations, please take a look at chapter 8. there you can see how the
different elements can be adjusted.
Your local agent is responsible to do the final tuning of the adjustment. Therefore

4. Control unit
4.1. VR2-control
4.1.1. On-/ Off-button
4.1.2. Battery gauge
On the control unit you can find a
joystick, buttons and symbols, where
we take a closer look at in the
following.
With the On-/ Off-button the chair
can be turned on or switched off.
Don’t use this button to stop the
wheelchair, unless there is an
emergency.
The battery gauge shows you that
the wheelchair is switched on and it
shows you how much power there is
left in the batteries. The gauge is also
used as an electronic fault detection
(see chapter 16.)

17
4.1.3. Joystick
4.1.4. Speed
Joystick
The joystick controls the direction
and speed of the wheelchair.
To drive forwards push the joystick
forwards. The further you push it
from the centre the faster the
wheelchair will move. Let go of the
joystick and the wheelchair will stop
and the brakes come on.
For backwards driving push the
joystick backwards. Pushing the
joystick to the right side means a
right hand curve as a reaction.
Pushing the joystick to the left then
the chair will drive to the left hand
side.
The joystick can be used to choose
and to move the actuators as well
(see chapter 4.1.5.).
Speed gauge
This is a gauge that shows the
maximum speed setting for the
wheelchair. This gauge also indicates
if the speed of the wheelchair is
being limited or if the control system
is locked.
If one LED is illuminated, you drive
with the slowest speed, 5 illuminated
LED’s mean that you drive with the
highest programmed speed.
If the LED’s are flashing, it means
the speed is reduced. That happens
when you go into standing position.
If the LED’s are ripple up and down,
it means the chair is locked.

18
Standard chair without light:
By pressing the left actuator-button,
you can activate the stand-up
function. If you move the joystick
forward, the chair is rising upwards, if
you move the joystick backwards, the
chair is moving downwards.
If your chair is equipped with the
option “Tilt in space”, it can be
activated by pressing the right
actuator-button. If you move the
joystick backwards, the complete
seat is tilting backwards, if you press
the joystick forward, the seat is
moving back to the horizontal
position.
Chair with light:
If your chair is equipped with light,
you just have one button to choose
the actuators. To activate the stand-
up function, press the actuator-
button, deflect the joystick to the left,
until the left LED under the actuator-
button is illuminated. Now you can
move the joystick forward to bring
the chair into the stand-up position,
to go down into the seating position,
you just need to move the joystick
backwards.
If you have the option “Tilt in space”
on your chair, to choose this
actuator, press the actuator-button
and move the joystick to the right,
until the right LED is illuminated. If
you move the joystick backwards, the
complete seat is tilting backwards, if
you press the joystick forward, the
seat is moving back to the horizontal
position.
