2.6 Safety requirements for care,
Maintenance and Disposal
r
Only trained specialists who have been authorised by
Otto Bock may do maintenance work on the power
wheelchair. This also applies to all repairs and settings
on the brakes. Incorrect settings can lead to brake
failure.
r
The fuse must always be removed for any maintenance
work where the battery cover is open.
r
Never use a water jet or high-pressure cleaning
ap paratus for cleaning the power wheelchair. The
water may not come into direct contact with the elec-
tronics, motor or battery.
r
Defective batteries must be disposed of properly in
accordance with national regulations.
2.7 requirements for the user
r
The power wheelchair may only be used by informed
users. For this purpose, the user and maybe any attend-
ant must receive instructions on how to use the power
wheelchair from trained specialists who have been
authorised by Otto Bock.
r
The user must have read and understood all the infor-
mation in the instructions for use.
r
The wheelchair may not be operated in cases of
exhaustion or under the influence of alcohol or drugs.
The user may not have any mental restrictions which
can temporarily or permanently restrict attentiveness
and judgement.
r
Before using the power wheelchair for the first time,
the user must become familiar with the wheelchair on
level ground first. This can help to avoid potentially
dangerous situations such as tipping. Getting to know
how the power wheelchair reacts when the centre of
gravity shifts, for example, on slopes or inclines or
when clearing obstacles like steps and curbs should
be done only with assistance from another person
before using the wheelchair for the first time.
r
When driving in the dark, it is strongly recommended
that the user wear bright clothes or clothing with
reflectors.
2.8 Safety functions
In dangerous situations, the B500 can be turned off at
any time using the on/off button. When the button is
pressed, the power wheelchair brakes immediately.
If any malfunctions occur such as an insufficient supply
of energy to the brake, the software will recognise them
and trigger the emergency stop brake or reduce the
speed of the power wheelchair. At the same time, an
acoustic warning signal will be emitted.
