Safety
control) must be made to comply with the individual
requirements and abilities of the user. The settings
may only be made by trained specialists who have
been authorised by Otto Bock.
r
The B500 may be used within a temperature range of
-25 °C to +50 °C. During operation, the wheelchair
may not be exposed to temperatures below or above
this range.
r
The maximum load for the B500 is 140 kg/309 lbs.
This load must not be exceeded.
r
The lift seat function may only be used on horizontal
surfaces and only with a vertical back angle.
r
The seat function actuators are not intended for con-
tinuous use, but only for short-term limited operation
(10 % use, 90 % idle time). General recommendation:
Under maximum load, a pause of approximately 90
seconds is required after 10 seconds of operation.
The electric seat functions are considered independ-
ently of the driving function for this purpose.
r
The lift seat may only be subjected to a maximum load
of 130 kg.
r
The lift seat may not be operated in case of errors or
malfunctions. If creep speed is not activated when the
lift seat is operated, please visit a specialist dealer
immediately. The power wheelchair may only be used
with the seat in its lowest position until the problem is
corrected.
r
The power wheelchair must be visually checked every
time before it is used to make sure the tread depth is
sufficient and that the tyres are inflated to the correct
tyre pressure (printed on the sidewall of the tyre).
r
When the wheelchair is used on the street, its user is
required to obey the public traffic regulations.
r
Using the power wheelchair on very slippery ground
(such as icy surfaces) is not permitted. Driving on very
coarse-grained surfaces (gravel or pebbles) is not
permitted either.
r
When getting into or out of the power wheelchair, the
controls must be switched off. The footrests and arm-
rests are not capable of bearing full body weight, and
therefore must not be used for getting into or out of
the wheelchair.
r
The critical obstacle height of the B500 is 5 cm. Dif-
ferences in height greater than 5 cm must not be
crossed.
r
Risk of injury if the power wheelchair tips over! Before
driving up slopes or over obstacles, a tilted seat must
be lowered to its basic position and the back must be
brought into the upright position.
r
Drive over obstacles such as steps or curbs at reduced
speed only (max. 3 km/h). Always approach obstacles
at a right angle and cross over them without stopping.
