2 About these instructions
Read these operating instructions before
commissioning the bicycle in order to use all the
functions correctly and safely. They are not a
substitute for personal training by the supplying
HERCULES specialist dealer. The operating
instructions are a component part of the bicycle.
Therefore, if it is re-sold at a later time, they must be
handed over to the subsequent owner.
These operating instructions are mainly directed at the
rider and user of the cycle. In general, they are
technical laypersons.
Staff at all HERCULES specialist dealers have
specialist training and qualifications, and are therefore
capable of identifying risks and preventing hazards
which may arise during maintenance, servicing and
repairs on the bicycle. Information for specialist staff
does not require technical laypersons to take any
action.
