Does the noise
persist?
The noise is being caused by
the movement of the pedal arm
bracket against the roller wheel.
This movement is a normal
function of the machine. A level
of “play” has been built into the
pedal arm / roller wheel to
reduce internal mechanical
stress, and to increase the
longevity of the machine.
