belt slips, proceed using the same technique as
described above. Please note that a belt drive gear
never shows slack. In case of adjustment do not
apply too much tension.

the belt of 3200 Hz ± 150Hz. Ball bearing damage
due to incorrect belt tension is excluded from
warranty.

A loose belt as well as an overtightened
belt may cause injury of the rider or damage to the
drive system.

To check for
a loose belt, sit on the saddle, place your feet on
the pedals, move the pedals until the crank arms
are horizontal. Next, pull up the emergency brake
handle and hold it. Then, stand on the pedals and
rock forward and backward. There should be
no
play or slip in the drive train. If there is slip or play
in the drive train, this indicates that the belt is too
loose.
