Safety
r
Manoeuvring is only allowed at a reduced speed.
r
To lift the wheelchair, grasp it by frame components
only! Never grasp the footrests or armrests to lift the
wheelchair.
r
All attendants must be informed that there are pinch
points caused by the construction in the area between
the seat frame and wheelchair frame. Users and
attendants must no reach into the danger area.
r
The controls of the power wheelchair are protected
according to protective system IP 54 and can thus be
used in bad weather (e. g. rain). The controls have
been approved for indoor and outdoor use and com-
ply with the requirements for climate and splashing
water.
r
The power wheelchair has been tested according to
EMC regulations. The following particularities must
be observed when using the wheelchair:
– The driving characteristics of the power wheelchair
can be influenced by electromagnetic fields (mobile
phones or other radiating devices). For this reason,
all mobile devices must be switched off when driving.
– The power wheelchair can generate electro magnetic
fields that can cause interference with other devices.
Therefore, switch off the controls whenever you do
not need them.
r
The tyres of the power wheelchair contain chemical
substances that can react to other chemical sub-
stances (such as cleaning agents, acids, etc.).
r
Direct sunlight (UV light) causes the tyres to age pre-
maturely. As a result, the tread surface hardens and
corner pieces break out of the tread.
r
Whenever possible, avoid parking the wheelchair
outdoors. Regardless of wear and tear, the tyres should
be replaced every 2 years.
r
Black tyres contain sooty particles, which can leave
traces on the ground. For this reason, a suitable mat
should be placed underneath the wheelchair, if it is
not going to be used over an extended period of time.
r
The B500 has been approved for driving on inclines
and slopes of no more than 17 %. It is not permitted
to drive on inclines or slopes steeper than this.
r
As a precaution, the driving speed must be reduced
when driving downhill (e.g. set it to speed level 1).
r
When the brake is released, there is not any brake
function available. This must be taken into account,
especially when driving on slopes or inclines.
r
After each emergency stop, the controls of the power
wheelchair must be turned on again. In the event of
communication problems in the bus system of the
controls, the system triggers an emergency stop and
thus prevents any uncontrolled functions. If the driving
function is still not available after switching on the
