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.

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.

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.
