Please note the following:
• The instructions for use (qualified personnel) are inten
ded only for qualified personnel and remain with them.
• The operation of the product and functionality of the
options are described in the instructions for use (user).
These instructions for use must be given to the user.
• All users and/or their attendants must be trained by you
in use of the product with the aid of the instructions for
use (user). In particular, the user(s) and/or attendant(s)
must be informed of the residual risk using the safety
instructions in the instructions for use (user).
• The manufacturer recommends checking the product

2 Application
2.1 Intended Use
The wheelchair is intended solely for personal use by people
who are unable to walk or have a walking impediment, as a
means of transport operated by themselves or another per
son for everyday indoor and outdoor use. An option is avail
able to allow an attendant to control the power wheelchair

design allow the product to be used by people who are
unable to walk or have a walking impediment, for example
due to:
• paralysis (paraplegia/tetraplegia)
• loss of limbs (leg amputation)
• limb defects/deformation
• joint contractures/damage
• neurological and muscular diseases
The following aspects should also be considered for custom
fittings:
• body size and body weight (max. load capacity 140
kg/308.6 lbs for standard version)
• physical and mental condition
• age of the patient
• living conditions/environment
2.3 Contraindications

4 Delivery
4.1 Scope of supply
The scope of delivery includes:
• Fitted power wheelchair with main components
• Options installed according to the order
• Battery charger
• Instructions for use (qualified personnel), instructions
for use (user)
4.2 Options
The functionality and operation of the options are described
in more detail in the instructions for use (user).
All of the available options/accessories are listed on the
order form.
4.3 Storage
NOTICE
Deep discharge due to standby current
Risk of battery damage
►Remove the fuse if the wheelchair is not used for more
than 3 days.
INFORMATION
To remove the fuse: Opening the battery drawer/tray et
seq.
Storage conditions
• Maintain an ambient temperature between -15°C and
+40°C / 5°F and +104°F and a relative humidity
between 45% and 85%.
• Store the product in a dry, enclosed room with sufficient
air circulation and protection from external influences.
• Protect the wheels against ground frost, e.g. by reliev
ing them completely through assembly blocks or
wooden boards.
• Fill the wheels with slight overpressure and rotate them
at regular weekly intervals to prevent flat tyres from
extended standing.
Note regarding the tyres
• If the product is not moved for several days, permanent
colour changes may occur where it comes into contact
with the surface it is standing on. We therefore recom
mend using a suitable mat when parking it for extended
periods of time.
• Tyres contain chemical substances that can react with
other chemical substances (such as cleaning agents,
acids, etc.).
• Black tyres contain soot particles. They may leave black
marks where they come into contact with the ground.
Therefore the manufacturer recommends grey tyres if
the product is primarily used indoors.
Ottobock | 11B500 plus
Delivery

12 | Ottobock B500 plus
Delivery
• Avoid unnecessary parking outdoors. Direct exposure to
sunlight/UV radiation causes the tyres to age more
quickly. As a result, the tread surface hardens and
corner pieces break out of the tread.
• The tyres must be changed when the tread is less than
1mm / 0.04" to ensure safe driving behaviour.
• The tyres should be replaced every 2 years regardless
of wear and tear.
5 Preparation for Use
5.1 Tools required
The following tools are required for fine adjustments/set
tings:
• Allen keys in sizes 2 – 8
• Ring/open-end wrenches in sizes 8 – 24
• Size 8 – 20 socket wrenches
• Phillips screwdriver, size 2
• Torque wrench (measurement range 5-50 Nm)
5.2 Initial operation
WARNING
Incorrect charging or use of the battery
Risk of injury due to fire or explosion, battery damage,
short circuit

►Only use insulated tools to perform maintenance work
on the batteries.
►Ensure correct polarity when you connect the battery
cables. Connect the black cable to the negative termin
al and the red cable to the positive terminal.
NOTICE
Insufficient ventilation of the battery charger while
charging
Risk of damage to the battery charger

5.2.4 Charging the battery
See the power wheelchair instructions for use (user) for all
information regarding the charging process.
5.2.4.1 Battery charging information
The range of the power wheelchair is determined by the bat
tery capacity. The battery capacity is influenced by many
factors. In addition to the temperature, battery age and driv
ing conditions, the charging cycle also has a pronounced
effect on the capacity and therefore on the range.
Batteries reach their full capacity only after 20 - 30 charge
cycles. Only if the full capacity of the batteries has been
reached can the power wheelchair achieve the stated range.
At temperatures of < 0°C/32°F the battery capacity drops
by up to 35% in relation to the capacity for an outside tem
perature of 20°C/68°F. This shortens the range of the
power wheelchair accordingly. Moreover the charge level
displayed on the control panel can differ more significantly
from the actual battery capacity.
The following information should be observed for an optimal
charging cycle:
• The batteries can be charged at any time, regardless of
the remaining battery capacity.
• It takes about 10 hours until a discharged battery (only
1 flashing segment) is completely charged. When the
charging process is complete, the battery charger can
remain connected to the power wheelchair with no risk
of overcharging or damaging the battery. The battery
charger features a programmed recharging phase that
will maintain the battery capacity at the level that has
been reached.
• If the power wheelchair is used every day, the battery
should be charged every night.
• Never discharge the batteries completely (deep dis
charge).
• The batteries will gradually discharge if the wheelchair
is not used for extended periods of time. If the power
wheelchair is not used for an extended period, the bat
teries should be charged 1 x per week to maintain their
capacity.
• The fuse should be removed if the wheelchair is not
used for more than 3 days.
• The power wheelchair control unit must be switched off
while the batteries are charging to allow all of the char
ging current to be fed into the battery.

properly and that the service and maintenance instructions
are observed. Storage times at the dealer or with paying
parties are not included in this period. However, we would
like to emphasise that the product is reliable far beyond this
defined period of time, provided that it is cared for and
maintained properly.
The product must first be thoroughly cleaned and disinfec
ted before it can be re-used. Then the product must be
examined by an qualified specialist to check the condition
and to look for wear and possible damage. All worn and
damaged parts as well as components which do not fit or
are unsuitable for the new user must be replaced.
Detailed information on replacing components as well as
information on the required tools and the prescribed service
intervals can be found in the service manual.
