CAUTION
Risk of accidents or injury due to incorrect chain settings. An improperly adjusted chain can lead
to steering system malfunctions. Ensure that the steering casters and drive wheels are parallel and in
line with each other after tightening the chain, so that the steering direction corresponds to the pro-
gramming of the power wheelchair.
NOTICE
Risk of damage due to the improper completion of maintenance tasks. The removal and instal-
lation of the chain may only be completed at the plant of Otto Bock Manufacturing Königsee GmbH.
NOTICE
Risk of tyre damage. Incorrect chain settings may lead to uneven tyre wear, which can have a nega-
tive impact on the driving characteristics of the power wheelchair.
