1. INTRODUCTION
1.1. Purpose of the product
Balder wheelchairs are multifunctional electric wheelchairs which are very
comfortable and highly flexible in terms of functionality. Balder wheelchairs
combine the qualities of an outdoor chair with the flexibility of an indoor
model and are designed for daily use in all situations.
1.2. Making your chair ready for use
Before you start to use your chair, we recommend that you make sure your
chair is adjusted to meet your own specific needs. Each chair comes with
simple control and adjustment options to help you sit as comfortably as
possible. Find out more about the control and adjustment options in the
technical description.
1.3. Individual labelling
All Balder wheelchairs are labelled individually with their own unique serial
number. This is located on the chassis, between the wheels.
Always quote the serial number of your chair if you require any assistance.
1.4. Contact addresses if you require assistance
Contact your local dealer or the Assistive Device Centre in your district if you
need any assistance. See also the troubleshooting list in section 9.
Page 6 of 45 User manual Introduction
1.5. Use of hazard symbols
All warnings must be heeded in order to avoid injury to people or damage to
machinery or the environment. The following three hazard symbols will be
used in this book.
DANGER
If you do not follow these instructions, staff WILL be seriously injured.
WARNING
If you do not follow these instructions, machinery WILL be seriously
damaged.
NOTE
If you do not follow these instructions, staff MAY be injured or machinery or
the environment MAY be damaged.
1.6. Available documentation
If you have problems reading this manual, it is also available in electronic
format so that the text and pictures can be enlarged, etc. if so required. Contact
your local dealer if you need an electronic copy.
1.7. The environment
These chairs must be sorted at source in accordance with applicable
regulations on waste. Batteries and electronic equipment in particular must be
taken into account.

2. KEY DATA
2.1. Restrictions during normal use
2.1.1. Number of people
All Balder wheelchairs are designed to transport one – 1 – person.
Never allow anyone else to ride with you, either behind you or on the footrests.
2.1.2. Surfaces
DANGER
Take care when using the wheelchair on uneven, wet or slippery surfaces
(gravel, loose sand/earth, wet grass, etc.). These are conditions in which
you could overturn or lose control of your chair.
Bear in mind that negotiating obstacles can involve a risk of overturning.
Remember that your chair is heavy. Do not travel in areas where there is
a risk of the surface on which you are travelling collapsing.
Avoid travelling through water more than 7 cm deep. This may damage
the electric motor and systems, as well as the battery.
When travelling on slopes in excess of 6 degrees, remember that this will
affect the stability of the chair and there is a risk of the chair
overturning.
2.1.3. Descending slopes
NOTE
When your vehicle drives downhill, the motor generates energy. This
energy charges the battery. However, if the battery is already fully
charged, it cannot accept the generated energy anymore. When this
happens the battery voltage becomes too high, which can result in
damage to either the controller or the batteries. The controller will try to
prevent this damage and if needed it will ultimately force the vehicle to
halt abruptly.
When you go downhill at a slower speed, the motor will generate less
energy. The batteries will have more time to absorb this energy before
they are fully charged. This will reduce the risk of a sudden halt, and it
will extend the life of the batteries.
Page 8 of 45 User manual Key data
To have a smooth journey downhill:
• Select a drive profile that has a lower maximum speed
• If your vehicle has lights, turn them on. The lights will use
energy, and as a result less energy will go to the batteries. This
allows you to go downhill at a slightly faster speed than with the
lights off.
• When the LEDs of the battery gauge start to flash as a warning
that the batteries are overcharging, do not ignore this warning.
Drive at a lower speed. If you do not slow down, you will damage
the batteries. When your speed has been too fast for too long,
the vehicle will halt to prevent more damage.
• If you often need to go downhill with fully charged batteries, ask
your installer/technician/therapist to optimize the program values
of your chair for your situation.

3.2.2. Operating program
This chair is preprogrammed with five different default operating programs.
The illuminated display shows the program or function that you are using.
The operating program is selected by pressing the program
selector switch.
The various operating programs are as follows:
1. An operating program in which emphasis is placed on quiet movements
and low speed, a typical program which can be used where there is not
much space and precise movement is important.
2. An operating program very like program 1, but with slightly faster
reactions to joystick movements.
3. An operating program defined according to average values. This
program is ideal the first time you use the chair.
4. Programs which are intended to be used as standard once you have
learned how the chair reacts and feel secure in all situations. This
program is created to allow rapid feedback to your control operations,
maximum speed and rapid application of the motor brake.
5. This program is designed for outdoor operation and gives maximum
forward propulsion without being too sensitive to minor corrections.
3.2.3. Wheelchair attachment points
There are attachments on the wheelchair – 2 in front (1) and 1 ring (2) at the
rear. These are indicated by means of symbols as shown in the illustration.
Front: Rear:
For securing the wheelchair during transportation, see section 1.
Page 14 of 45 User manual Technical description
3.2.4. Attendant control (optional extra)
All Balder chairs are available with attendant control. This guide describes a
standard attendant control. See also section 5.4.1 for more information.
Attendant control:
1. Fixing bracket
2. Panel for electrical functions
3. Ring for moving the wheelchair
forwards or backwards.
4. Speed regulator
5. Ring for turning the chair
6. Switches for changing the
attendant control angle
7. Rotary switch for selecting
whether the user or the escort is to
control the chair
