4.3 Storage
4.3.1 During daily use
The power wheelchair should always be protected against
external influences.
The control unit must be turned off.
4.3.2 In case of extended disuse
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: see Page80 et. seq.
Please observe the following if the power wheelchair is not
used for more than 3 days:
Storage Conditions
■Maintain an ambient temperature between -40 °C and
+65 °C (-40 °F to 149 °F) and a relative humidity
between 45 and 85 %.
■Store the power wheelchair in a dry, enclosed room
with sufficient air circulation and protection from extern
al 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 tires
■If the power wheelchair is not moved for several days,
permanent colour changes may occur where the
wheelchair comes into contact with the surface it is
standing on. Therefore a suitable underlay should be
used if the wheelchair is parked for extended periods of
time.
■Tires contain chemical substances that can react with
other chemical substances (such as cleaning agents or
acids).
Delivery
03/2011

Page 15B500 classic/advanced
■Black tires contain soot particles. They may leave black
marks where they come into contact with the ground.
Therefore Otto Bock recommends grey tires if the
wheelchair is primarily used indoors.
■Direct sunlight/UV light causes the tires to age prema
turely. As a result, the tread surface hardens and
corner pieces break out of the tread.
■Avoid unnecessary parking outdoors. The tires should
be replaced every 2 years regardless of wear and tear.
